Hi Again,

So having sorted out how to make a Teno generated HBM get used, I found my
next difficulty. I'm using the genmodel to create SDO objects and when Teno
reads the sdo objects to build the mapping everything works great and I get
hbm that looks like this:

<class name="com.vsp.consumer.impl.ConsumerImpl"
entity-name="Consumer"
abstract="false" lazy="false" discriminator-value="Consumer"
table="`cmr3601t`">
<meta attribute="eclassName">Consumer</meta>

The key thing here is taht the name="com.vsp.consumer.impl.ConsumerImpl"

<class name="org.eclipse.emf.ecore.impl.DynamicEObjectImpl"
entity-name="Consumer"
abstract="false" lazy="false" discriminator-value="Consumer"
table="`cmr3601t`">
<meta attribute="eclassName">Consumer</meta>

This blows up when I try to use this hbm because the data store
initialization expects DynamicEObjectImpl to have getters and setters for
all my fields in the same way that ConsumerImpl does.

I use the "Set SDO defaults" on the gen model before I generate the model
code since I have to have pojos for my clients to interact with. Is there
some similar configuration that I need to set for Teneo to put the correct
names in place?

If there's a feature enhancement to be done here, let me know. I'm looking
at the code as well, but I thought I'd ask since the solution isn't jumping
out at me.

I've gotten my local teneo version to put <comment> tags into the hbm from
the ecore. Once I can fix this and prove that that my objects will work,
I'll be about ready to submit that to you as well.

Hi Jason,
I am not sure how you got the DynamicEObjectImpl in the hbm file.
This happens in case of a dynamic emf model (without generated java code). This is a current bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=193052
I have solved this in cvs. If it is this bug then to work around this for now you can remove this
from the hbm:
name="org.eclipse.emf.ecore.impl.DynamicEObjectImpl"
(a global search and replace will work)

Still, I don't really understand why it does not pick up the CustomerImpl class.
You can also programmatically create the hbm file (see the HbHelper class) this is safer from a
classloading point of view and allows you to pass options when generating the hbm.

This is a current bug:
> https://bugs.eclipse.org/bugs/show_bug.cgi?id=193052

For me, the class name information is not present because I run teneo with
only the ecore available by invoding the main in GenerateHBM. I tried
putting the SDO classes into the class path but it wasn't enough and no good
naming was found.

Applying the fix from CVS also didn't work out completely. It helped in
that the name attribute was not present until runtime and so the mappings
would generate but two other problems came up:
- Enumeration types still failed because the name wasn't present and so it
couldn't find the correct values
- Relationships didn't work because the keys information couldn't be found.

So I used teneo at run time, captured the output HBM and kept hacking at the
ecore-only generation method until I could get the same result. The main
problem was that there was no way to get the java package because that
information doesn't get put in the .ecore file.

I control the output package for the java files by using ecore:package like
this:

<xsd:schema targetNamespace="http://vsp.com/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:vsp="http://vsp.com/"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
ecore:package="com.vsp.consumer">

But ecore:package only goes to the genmodel, not to the ecore file. Luckily
I discovered nsPrefix:

<xsd:schema targetNamespace="http://vsp.com/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:vsp="http://vsp.com/"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
ecore:package="com.vsp.consumer"
ecore:nsPrefix="com.vsp.consumer">

By putting this into the XSD, I can get a hold of it in the ecore. From
there I generate all the names in the same way that the SDO code generator
will and everything comes out perfectly. The names are specified correctly,
the keys and the enums all work great.

Basically, I keep the current fix, but when I'm generating the xml for the
entity I add

target.addAttribute("name",
entity.getAnnotatedEClass().getEPackage().getNsPrefix()+".impl. "+
entity.getEntity().getName()+"Impl");

I'd like to make another property that will control wether or not to use the
nsPrefix like that. It seems like this is what the nsPrefix attribute was
put in there for and as fas as I can tell teneo isn't really using it any
differently in the few places that it uses it at all. I was thinking about
a property like USE_NS_PREFIX_FOR_JAVA_NAME_GENERATION to control wether
this gets used or not, but whatever you like is good for me.

Let me know what you think, and I'll make another submission for this. I'll
keep three submissions seperate so you can review them individually. I've
got Comments, UseSpecificHBMFile and now nsPrefixForPackage as the three
things I'm about ready to send your way.

Talk to you soon,

Jason Henriksen

Hi Jason,
I am not sure about using the nsprefix. Teneo/Hibernate should also work with dynamic emf (so no
generated java code). What goes exactly wrong in these two cases?

How does the hbm look like in this case?

I agree that nsPrefix isn't the prettiest thing in the world, but =
without the java package I run into these two problems:

=3D=3D PROBLEM 1:
When I first applied the fix in CVS I started seeing the enumerated =
types fail. I got this hbm
<type =
name=3D"org.eclipse.emf.teneo.hibernate.mapping.DynamicENumUserType ">
<param name=3D"eclassifier">RelationshipCodeType</param>
<param name=3D"epackage">http://vsp.com/</param>
</type>
Instead of the runtime generated hbm which looks like this:
<type =
name=3D"org.eclipse.emf.teneo.hibernate.mapping.ENumUserType ">
<param =
name=3D"enumClass">com.vsp.consumer.RelationshipCodeType</param >
</type>

The basic problem is that it tries cast DynamicENumUserType to the =
specific enumation type that I've defined, but that it doesn't know =
about from the ecore. Here's the exception:

java.lang.ClassCastException: com.vsp.consumer.GenderCodeType
Hibernate: /* insert Consumer */ insert into "cmr3601t" ("isd_lock_ct", =
"consumer_id", "name_prefix", "first_name", "middle_initial", =
"last_name", "name_suffix", "ssn", "date_of_birth", "gender_cd", =
"marital_status_cd", "citizenship_ind", "disability_ind", =
"ethnicity_cd", "other_id", "other_id_type_cd", "personal_info", =
"place_of_birth", "prefer_comm_method", "isd_lupd_id", econtainer_class, =
e_container, e_container_featureid, "dtype", "consumer_sk") values (?, =
?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, =
'Consumer', ?)
at =
org.eclipse.emf.teneo.hibernate.mapping.DynamicENumUserType. nullSafeSet(D=
ynamicENumUserType.java:137)
at org.hibernate.type.CustomType.nullSafeSet(CustomType.java:14 6)
at =

EntityPersister.java:1997)
at =
org.hibernate.persister.entity.AbstractEntityPersister.inser t(AbstractEnt=
ityPersister.java:2243)

I solve this by altering AbstractMapper like this:

private void handleEnumType(PAnnotatedEAttribute paAttribute, Element =
propElement) {
final Enumerated enumerated =3D paAttribute.getEnumerated();
assert (enumerated !=3D null);
final EAttribute eattr =3D paAttribute.getAnnotatedEAttribute();
final EClassifier eclassifier =3D eattr.getEType();
if (!getHbmContext().isGeneratedByEMF()
&& getHbmContext().getInstanceClass(eclassifier) !=3D null) {
final Class<?> instanceClass =3D =
getHbmContext().getInstanceClass(eclassifier);
propElement.addElement("type").addAttribute("name", =
getEnumUserType(enumerated))
.addElement("param").addAttribute("name", =
HbMapperConstants.ENUM_CLASS_PARAM)
.addText(instanceClass.getName());
} else if (getHbmContext().isGeneratedByEMF() && =
eclassifier.getInstanceClass() !=3D null) {
propElement.addElement("type").addAttribute("name", =
getEnumUserType(enumerated))
.addElement("param").addAttribute("name", =
HbMapperConstants.ENUM_CLASS_PARAM)
.addText(eclassifier.getInstanceClass().getName());
}=20
//--- JJH
else if (true) { // would be a property
=20
// brute force this to behave by letting the user specify what =
package should be used.
// If this is not enabled, enumerations are treated as the wrong =
type.
// This is ONLY needed if you are generating .hbm directly from =
..ecore without using annotated class files. =20
String packageName =3D eclassifier.getEPackage().getNsPrefix();
propElement.addElement("type").addAttribute("name", =
getEnumUserType(enumerated))
.addElement("param").addAttribute("name", =
HbMapperConstants.ENUM_CLASS_PARAM)
.addText(packageName+"."+eclassifier.getName());
}
//--- JJH
else { // must be emf dynamic
final Element typeElement =3D
propElement.addElement("type").addAttribute("name",
hbDynamicEnumType(enumerated));
typeElement.addElement("param").addAttribute("name",
HbMapperConstants.ECLASSIFIER_PARAM).addText(eclassifier.get Name());
typeElement.addElement("param").addAttribute("name", =
HbMapperConstants.EPACKAGE_PARAM)
.addText(eclassifier.getEPackage().getNsURI());
}

}

=3D=3D PROBLEM 2:
So if I fix the CCE above with that bit of hardcoding and still let the =
output hbm look like this:
<class entity-name=3D"Address" abstract=3D"false" lazy=3D"false" =
discriminator-value=3D"Address" table=3D"`cmr3605t`">
instead of how it should look as in this example:
<class name=3D"com.vsp.consumer.impl.AddressImpl" =
entity-name=3D"Address" abstract=3D"false" lazy=3D"false" =
discriminator-value=3D"Address" table=3D"`cmr3605t`">

I end up with this mess when I relate the objects (-530 means invalid =
foreign key value. Basically, it doesn't know how to map the =
relationships and puts a bad value into the jdbc statement):

-----------------------

I solve this with this bit of code in EntityMapper.java:

private Element createEntity(PAnnotatedEClass entity,
InheritanceType inhStrategy, =
PAnnotatedEClass superEntity,
DiscriminatorValue dValue, =
Table table) {

...
final Element target;

final String entityName =3D getHbmContext().getEntityName(eclass);
final String isAbstractStr =3D eclass.isAbstract() ? "true" : "false";
if (entity.isOnlyMapAsEntity()) {
target =3D getHbmContext().getCurrent().addElement(hbClassName);
=20
if (hasCompositeID(entity)) { // only for this specific case
String foo =3D =
hbmContext.getInstanceClassName(entity.getAnnotatedEClass()) ;
target.addAttribute("name", foo);
}
//--- hard code fix for missing class files.
else{ =20
//--- JJH
target.addAttribute("name", =
entity.getAnnotatedEClass().getEPackage().getNsPrefix()+".impl. "+entity.g=
etEntity().getName()+"Impl");
//--- JJH
}
...

I probably need to fix the name attribute in more places than this, but =
doing it here makes all my code work.

=3D=3D OTHER POSSIBLE SOLUTIONS:

I thought about putting the package prefix that I need into a property, =
but that's no fun because I'd have to change it every time I ran another =
ecore file through. Ideally there should be something in the ecore that =
would hold the package name, but it's not there. And since I can =
specify any random value for ecore:package in the xsd I really need to =
have the right string in order for things to match up at runtime. =20

I considered adding annotation to the basic schema level, but the =
annotations only come through on the actual entity objects. I didn't =
want to re-specify the package on every entity because that seems even =
more redundant than using nsPrefix.

I also found nsPrefix being used in a somewhat similar way in the =
existing teneo code here:

HibernateFeatureMapEntry:
/** Code copied from FeatureMapUtil.EntryImpl */
public String toString() {
String prefix =3D =
eStructuralFeature.getEContainingClass().getEPackage().getNs Prefix();
eStructuralFeature.getName();
return (prefix !=3D null && prefix.length() !=3D 0 ? prefix + ":" + =
eStructuralFeature.getName()
: eStructuralFeature.getName())
+ "=3D" + getValue();
}

and in QualifyingEClassNameStrategy

public String toUniqueName(EClass eClass) {
if (eClass =3D=3D null) {
throw new IllegalArgumentException("EClass cannot be null.");
}
if (eClass =3D=3D EOBJECT_ECLASS) {
return EOBJECT_ECLASS_NAME;
}
String nsPrefix =3D eClass.getEPackage().getNsPrefix();
if (nsPrefix =3D=3D null) {
nsPrefix =3D eClass.getEPackage().getName();
}
return nsPrefix + "." + eClass.getName();
}

Not quite the same, but close enough that it seemed like a reasonable =
fit. =20
I'm completely open to any other solution you might suggest.

Remember that both of these problems do not exist if you're letting =
teneo run when the classes are available. Its only when you run =
GenerateHBM against an ecore with no other input and then force teneo to =
use that HBM that you run into these troubles.

Talk to you soon,

Jason=20

Hi Jason,
Does your enum value type implement EEnumLiteral?

How does the hbm look like for the second problem?

You can also send the ecore file to me so I can try this second issue.

The part of the code where you refer to where Teneo also uses the nsprefix is to create a unique
name for an EClass, this name is not a class name but just a unique string (which can be converted
back to the EClass).

Hi Jason,
I am not sure how you got the DynamicEObjectImpl in the hbm file.
This happens in case of a dynamic emf model (without generated java code). This is a current bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=193052
I have solved this in cvs. If it is this bug then to work around this for now you can remove this
from the hbm:
name="org.eclipse.emf.ecore.impl.DynamicEObjectImpl"
(a global search and replace will work)

Still, I don't really understand why it does not pick up the CustomerImpl class.
You can also programmatically create the hbm file (see the HbHelper class) this is safer from a
classloading point of view and allows you to pass options when generating the hbm.

Hi Martin,

This is a current bug:
> https://bugs.eclipse.org/bugs/show_bug.cgi?id=193052

For me, the class name information is not present because I run teneo with
only the ecore available by invoding the main in GenerateHBM. I tried
putting the SDO classes into the class path but it wasn't enough and no good
naming was found.

> I have solved this in cvs. If it is this bug then to work around this for

> name="org.eclipse.emf.ecore.impl.DynamicEObjectImpl"

Applying the fix from CVS also didn't work out completely. It helped in
that the name attribute was not present until runtime and so the mappings
would generate but two other problems came up:
- Enumeration types still failed because the name wasn't present and so it
couldn't find the correct values
- Relationships didn't work because the keys information couldn't be found.

So I used teneo at run time, captured the output HBM and kept hacking at the
ecore-only generation method until I could get the same result. The main
problem was that there was no way to get the java package because that
information doesn't get put in the .ecore file.

I control the output package for the java files by using ecore:package like
this:

<xsd:schema targetNamespace="http://vsp.com/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:vsp="http://vsp.com/"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
ecore:package="com.vsp.consumer">

But ecore:package only goes to the genmodel, not to the ecore file. Luckily
I discovered nsPrefix:

<xsd:schema targetNamespace="http://vsp.com/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:vsp="http://vsp.com/"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
ecore:package="com.vsp.consumer"
ecore:nsPrefix="com.vsp.consumer">

By putting this into the XSD, I can get a hold of it in the ecore. From
there I generate all the names in the same way that the SDO code generator
will and everything comes out perfectly. The names are specified correctly,
the keys and the enums all work great.

Basically, I keep the current fix, but when I'm generating the xml for the
entity I add

target.addAttribute("name",
entity.getAnnotatedEClass().getEPackage().getNsPrefix()+".impl. "+
entity.getEntity().getName()+"Impl");

I'd like to make another property that will control wether or not to use the
nsPrefix like that. It seems like this is what the nsPrefix attribute was
put in there for and as fas as I can tell teneo isn't really using it any
differently in the few places that it uses it at all. I was thinking about
a property like USE_NS_PREFIX_FOR_JAVA_NAME_GENERATION to control wether
this gets used or not, but whatever you like is good for me.

Let me know what you think, and I'll make another submission for this. I'll
keep three submissions seperate so you can review them individually. I've
got Comments, UseSpecificHBMFile and now nsPrefixForPackage as the three
things I'm about ready to send your way.

Talk to you soon,

Jason Henriksen

Hi Jason,
I am not sure about using the nsprefix. Teneo/Hibernate should also work with dynamic emf (so no
generated java code). What goes exactly wrong in these two cases?

How does the hbm look like in this case?

I agree that nsPrefix isn't the prettiest thing in the world, but =
without the java package I run into these two problems:

=3D=3D PROBLEM 1:
When I first applied the fix in CVS I started seeing the enumerated =
types fail. I got this hbm
<type =
name=3D"org.eclipse.emf.teneo.hibernate.mapping.DynamicENumUserType ">
<param name=3D"eclassifier">RelationshipCodeType</param>
<param name=3D"epackage">http://vsp.com/</param>
</type>
Instead of the runtime generated hbm which looks like this:
<type =
name=3D"org.eclipse.emf.teneo.hibernate.mapping.ENumUserType ">
<param =
name=3D"enumClass">com.vsp.consumer.RelationshipCodeType</param >
</type>

The basic problem is that it tries cast DynamicENumUserType to the =
specific enumation type that I've defined, but that it doesn't know =
about from the ecore. Here's the exception:

java.lang.ClassCastException: com.vsp.consumer.GenderCodeType
Hibernate: /* insert Consumer */ insert into "cmr3601t" ("isd_lock_ct", =
"consumer_id", "name_prefix", "first_name", "middle_initial", =
"last_name", "name_suffix", "ssn", "date_of_birth", "gender_cd", =
"marital_status_cd", "citizenship_ind", "disability_ind", =
"ethnicity_cd", "other_id", "other_id_type_cd", "personal_info", =
"place_of_birth", "prefer_comm_method", "isd_lupd_id", econtainer_class, =
e_container, e_container_featureid, "dtype", "consumer_sk") values (?, =
?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, =
'Consumer', ?)
at =
org.eclipse.emf.teneo.hibernate.mapping.DynamicENumUserType. nullSafeSet(D=
ynamicENumUserType.java:137)
at org.hibernate.type.CustomType.nullSafeSet(CustomType.java:14 6)
at =
org.hibernate.persister.entity.AbstractEntityPersister.dehyd rate(Abstract=
EntityPersister.java:1997)
at =
org.hibernate.persister.entity.AbstractEntityPersister.inser t(AbstractEnt=
ityPersister.java:2243)

I solve this by altering AbstractMapper like this:

private void handleEnumType(PAnnotatedEAttribute paAttribute, Element =
propElement) {
final Enumerated enumerated =3D paAttribute.getEnumerated();
assert (enumerated !=3D null);
final EAttribute eattr =3D paAttribute.getAnnotatedEAttribute();
final EClassifier eclassifier =3D eattr.getEType();
if (!getHbmContext().isGeneratedByEMF()
&& getHbmContext().getInstanceClass(eclassifier) !=3D null) {
final Class<?> instanceClass =3D =
getHbmContext().getInstanceClass(eclassifier);
propElement.addElement("type").addAttribute("name", =
getEnumUserType(enumerated))
.addElement("param").addAttribute("name", =
HbMapperConstants.ENUM_CLASS_PARAM)
.addText(instanceClass.getName());
} else if (getHbmContext().isGeneratedByEMF() && =
eclassifier.getInstanceClass() !=3D null) {
propElement.addElement("type").addAttribute("name", =
getEnumUserType(enumerated))
.addElement("param").addAttribute("name", =
HbMapperConstants.ENUM_CLASS_PARAM)
.addText(eclassifier.getInstanceClass().getName());
}=20
//--- JJH
else if (true) { // would be a property
=20
// brute force this to behave by letting the user specify what =
package should be used.
// If this is not enabled, enumerations are treated as the wrong =
type.
// This is ONLY needed if you are generating .hbm directly from =
..ecore without using annotated class files. =20
String packageName =3D eclassifier.getEPackage().getNsPrefix();
propElement.addElement("type").addAttribute("name", =
getEnumUserType(enumerated))
.addElement("param").addAttribute("name", =
HbMapperConstants.ENUM_CLASS_PARAM)
.addText(packageName+"."+eclassifier.getName());
}
//--- JJH
else { // must be emf dynamic
final Element typeElement =3D
propElement.addElement("type").addAttribute("name",
hbDynamicEnumType(enumerated));
typeElement.addElement("param").addAttribute("name",
HbMapperConstants.ECLASSIFIER_PARAM).addText(eclassifier.get Name());
typeElement.addElement("param").addAttribute("name", =
HbMapperConstants.EPACKAGE_PARAM)
.addText(eclassifier.getEPackage().getNsURI());
}

}

=3D=3D PROBLEM 2:
So if I fix the CCE above with that bit of hardcoding and still let the =
output hbm look like this:
<class entity-name=3D"Address" abstract=3D"false" lazy=3D"false" =
discriminator-value=3D"Address" table=3D"`cmr3605t`">
instead of how it should look as in this example:
<class name=3D"com.vsp.consumer.impl.AddressImpl" =
entity-name=3D"Address" abstract=3D"false" lazy=3D"false" =
discriminator-value=3D"Address" table=3D"`cmr3605t`">

I end up with this mess when I relate the objects (-530 means invalid =
foreign key value. Basically, it doesn't know how to map the =
relationships and puts a bad value into the jdbc statement):

-----------------------

I solve this with this bit of code in EntityMapper.java:

private Element createEntity(PAnnotatedEClass entity,
InheritanceType inhStrategy, =
PAnnotatedEClass superEntity,
DiscriminatorValue dValue, =
Table table) {

...
final Element target;

final String entityName =3D getHbmContext().getEntityName(eclass);
final String isAbstractStr =3D eclass.isAbstract() ? "true" : "false";
if (entity.isOnlyMapAsEntity()) {
target =3D getHbmContext().getCurrent().addElement(hbClassName);
=20
if (hasCompositeID(entity)) { // only for this specific case
String foo =3D =
hbmContext.getInstanceClassName(entity.getAnnotatedEClass()) ;
target.addAttribute("name", foo);
}
//--- hard code fix for missing class files.
else{ =20
//--- JJH
target.addAttribute("name", =
entity.getAnnotatedEClass().getEPackage().getNsPrefix()+".impl. "+entity.g=
etEntity().getName()+"Impl");
//--- JJH
}
...

I probably need to fix the name attribute in more places than this, but =
doing it here makes all my code work.

=3D=3D OTHER POSSIBLE SOLUTIONS:

I thought about putting the package prefix that I need into a property, =
but that's no fun because I'd have to change it every time I ran another =
ecore file through. Ideally there should be something in the ecore that =
would hold the package name, but it's not there. And since I can =
specify any random value for ecore:package in the xsd I really need to =
have the right string in order for things to match up at runtime. =20

I considered adding annotation to the basic schema level, but the =
annotations only come through on the actual entity objects. I didn't =
want to re-specify the package on every entity because that seems even =
more redundant than using nsPrefix.

I also found nsPrefix being used in a somewhat similar way in the =
existing teneo code here:

HibernateFeatureMapEntry:
/** Code copied from FeatureMapUtil.EntryImpl */
public String toString() {
String prefix =3D =
eStructuralFeature.getEContainingClass().getEPackage().getNs Prefix();
eStructuralFeature.getName();
return (prefix !=3D null && prefix.length() !=3D 0 ? prefix + ":" + =
eStructuralFeature.getName()
: eStructuralFeature.getName())
+ "=3D" + getValue();
}

and in QualifyingEClassNameStrategy

public String toUniqueName(EClass eClass) {
if (eClass =3D=3D null) {
throw new IllegalArgumentException("EClass cannot be null.");
}
if (eClass =3D=3D EOBJECT_ECLASS) {
return EOBJECT_ECLASS_NAME;
}
String nsPrefix =3D eClass.getEPackage().getNsPrefix();
if (nsPrefix =3D=3D null) {
nsPrefix =3D eClass.getEPackage().getName();
}
return nsPrefix + "." + eClass.getName();
}

Not quite the same, but close enough that it seemed like a reasonable =
fit. =20
I'm completely open to any other solution you might suggest.

Remember that both of these problems do not exist if you're letting =
teneo run when the classes are available. Its only when you run =
GenerateHBM against an ecore with no other input and then force teneo to =
use that HBM that you run into these troubles.

Talk to you soon,

Hi Jason,
Does your enum value type implement EEnumLiteral?

How does the hbm look like for the second problem?

You can also send the ecore file to me so I can try this second issue.

The part of the code where you refer to where Teneo also uses the nsprefix is to create a unique
name for an EClass, this name is not a class name but just a unique string (which can be converted
back to the EClass).

gr. Martin

> have the right string in order for things to match up at runtime.

> more redundant than using nsPrefix.

> I also found nsPrefix being used in a somewhat similar way in the

>
> HibernateFeatureMapEntry:
> /** Code copied from FeatureMapUtil.EntryImpl */
> public String toString() {
> String prefix =
> eStructuralFeature.getEContainingClass().getEPackage().getNs Prefix();
> eStructuralFeature.getName();
> return (prefix != null && prefix.length() != 0 ? prefix + ":" +
> eStructuralFeature.getName()
> : eStructuralFeature.getName())
> + "=" + getValue();
> }
> and in QualifyingEClassNameStrategy
>
> public String toUniqueName(EClass eClass) {
> if (eClass == null) {
> throw new IllegalArgumentException("EClass cannot be null.");
> }
> if (eClass == EOBJECT_ECLASS) {
> return EOBJECT_ECLASS_NAME;
> }
> String nsPrefix = eClass.getEPackage().getNsPrefix();
> if (nsPrefix == null) {
> nsPrefix = eClass.getEPackage().getName();
> }
> return nsPrefix + "." + eClass.getName();
> }
> Not quite the same, but close enough that it seemed like a reasonable fit.
> I'm completely open to any other solution you might suggest.

> Remember that both of these problems do not exist if you're letting
