Hi all,

I want to remove duplicat names and same type in the View 's fields.How can I do this.I want to use my util class.
related part for this topic :http://www.eclipse.org/forums/index.php/m/1063178/#msg_1063178
Could you help me
My grammar is below :

View returns View:
'View'
name=QualifiedName
'{'
'guID' '=' guID=STRING
'displayName' '=' displayName=STRING
('description' '=' description=STRING)?
'type' '=' type= ViewType
('fields' '=' ownedViewField+=ViewField (','ownedViewField+=ViewField)*)?
'}';

ViewField returns ViewField:
(field= [Field|QualifiedName]);
my util class is below :


public static ArrayList<Field> possibleFieldForViewField(View view){
ArrayList<Field> uniqueFields = returnUniqueParenListFields(view);
EList<ViewField> ownedViewFields = view.getOwnedViewField();
for (Iterator<ViewField> iterator = ownedViewFields.iterator(); iterator.hasNext();) {
			ViewField viewField = (ViewField) iterator.next();
			Field alreadyAddedField = viewField.getField();
			
			for(int i = 0; i < uniqueFields.size(); i++){
				Field field = uniqueFields.get(i);
				if(field.eClass().getName().equals(alreadyAddedField.eClass().getName()) && field.getName().equals(alreadyAddedField.getName())){
uniqueFields.remove(i);
				}
			}
		}
		
		return uniqueFields;
	}
}
public static ArrayList<Field> returnUniqueParenListFields(View view){
		ArrayList<Field> allFields = returnAllParenListFields(view);
		
		for(int i = 0; i < allFields.size(); i++){
			Field field1 = allFields.get(i);
			
			for(int j = i+1; j < allFields.size(); j++){
				Field field2 = allFields.get(j);
				
				if(field1.eClass().getName().equals(field2.eClass().getName()) && field1.getName().equals(field2.getName())){
allFields.remove(j);
					
				}
			}
		}	
		return allFields;	
	}
public static ArrayList<Field> returnAllParenListFields(View view){
		ArrayList<Field> allFields = new ArrayList<>();
		CustomList parentList = (CustomList) view.eContainer();
		
		EList<ContentType> ownedContentTypes = parentList.getOwnedContentType();
		for (Iterator<ContentType> iterator = ownedContentTypes.iterator(); iterator
				.hasNext();) {
			ContentType contentType = (ContentType) iterator.next();
			EList<Field> fields = contentType.getOwnedField();
			for (Iterator<Field> iterator2 = fields.iterator(); iterator2.hasNext();) {
				Field field = (Field) iterator2.next();
				allFields.add(field);
			}
		}
		
		return allFields;
	}

Hi,

once more your grammar is incomplete.
let us asume it looks like

Model:
	fields+=Field*
	views+=View*;
	
Field:
	"Field" name=ID
;	
	
View returns View:
'View'
name=QualifiedName
'{'
'guID' '=' guID=STRING
'displayName' '=' displayName=STRING
('description' '=' description=STRING)?
('fields' '=' ownedViewField+=ViewField (','ownedViewField+=ViewField)*)?
'}';

ViewField returns ViewField:
(field= [Field|QualifiedName]);

QualifiedName: ID ("." ID)*;

then the Proposal Provider could look like (written in Xtend):

class MyDslProposalProvider extends AbstractMyDslProposalProvider {
	
	override completeViewField_Field(EObject model, Assignment assignment, ContentAssistContext context, ICompletionProposalAcceptor acceptor) {
		val view = EcoreUtil2::getContainerOfType(model, typeof(View))
		val names = view.ownedViewField.map[vw|vw.field?.name].filter[v|v!=null].toList
		println (names)
		lookupCrossReference(assignment.terminal as CrossReference, context, acceptor, [
			IEObjectDescription d | names.contains(d.qualifiedName.toString)
		])
	}
	
}

Please NOTE: you will need a validator for duplicates as well since this only adapts proposals.

Hi Christian,

I will try it but not comes anything in the View's fields (val names = view.ownedViewField.map[vw|vw.field?.name].filter[v|v!=null].toList comes null)
and my finally grammar:

Content returns Content:'{'
'ct' name=QualifiedName
application=WebApplication
	'}'
WebApplication returns WebApplication:
	'WebApplication' name=Qualifiedname
ownColection+=Collection (ownColection+=Collection)*'}'
Collection returns Collection:'{'
'Collection' name=QualifiedName
ownWeb=Web '}'

Web returns Web:
	'Web'
	name=QualifiedName
	'{'(lists+=Liste (lists+=Liste)*)?
	(webs+=Web (webs+=Web)*)?
	'}'
Liste returns Liste:
	'Liste'
	name=QualifiedName
	'{'(cttype+=CType (cttype+=CType)*)?
	(ownedView+=View (ownedView+=View)*)?
	'}'
View returns View:
	'View'
	name=QualifiedName
	'{''type' '=' type= ViewType
	('fields' '=' ownedViewField+=ViewField (','ownedViewField+=ViewField)*)?
	'}';
ViewField returns ViewField:
	(field= [Field|QualifiedName]);
Field returns Field:
	LookUp | Boolean 


Field returns Field:
	LookUp | BooleanField 
;

CType returns CType:
	'CType'
	name=QualifiedName
	'{' ('parent' '=' parentContentType=[ContentType|QualifiedName])?
	'fields' '{'
	(ownedField+=Field (ownedField+=Field)*)?
	'}'
	'}';


LookUp returns LookUp:
	'LookUp'
	name=QualifiedName
	'{' 'text' name=STRING '}'
QualifiedName : 
	ID('.'ID)*
;

best regards

first there was a typo in my post, you should have found that

!names.contains(d.qualifiedName.toString)

should be the closure

what do you mean by

it but not comes in the View's fields

;(

and the grammar is not copy and pasteable Sad

( And a sample model is missing Sad

((
the fields have no name so they cannot be cross refd

and i do NOT get duplicate ownedFields proposed. ;((((

of course i had to fix the qualified name problem first (nameprovider or grammar+pp provider)

public class MyQNP extends DefaultDeclarativeQualifiedNameProvider{
	
	@Inject
	IQualifiedNameConverter qnc;

	QualifiedName qualifiedName(Field f) {
		System.out.println(f.getName());
		return qnc.toQualifiedName(f.getName());
	}
	
}

=> it always help to try things with a hello word example to get problems split

i never know what your current "hü oder hott" status is

Hi Christian,

I remove some rules in the grammar.I do it simplify .
Fistly :!names.contains(d.qualifiedName.toString) not understand it :( Sad

I use DefaultDeclarativeQualifiedNameProvider :retuns all field names :This warning can be switched off on the Team > Git > Confirmations and Warnings preference page.
******text
******created
******createdBy
******contentTYPE
******numberfield
******bool

 @Inject
			IQualifiedNameConverter qnc;

			QualifiedName qualifiedName(Field f) {
				System.out.println("******"+f.getName());
				return qnc.toQualifiedName(f.getName());
			}

Secondly :I want to say with (it but not comes in the View's fields ) :When I enter CTRL+SPACE,does not come nothing in the View's fields attribute. :(:(:(I used below code

override completeViewField_Field(EObject model, Assignment assignment, ContentAssistContext context, ICompletionProposalAcceptor acceptor) {
		val view = EcoreUtil2::getContainerOfType(model, typeof(View))
		println ("viewwwww"+view)
		val names = view.ownedViewField.map[vw|vw.field?.name].filter[v|v!=null].toList
		println ("namessss"+names)
		
		lookupCrossReference(assignment.terminal as CrossReference, context, acceptor, [
			IEObjectDescription d | names.contains(d.qualifiedName.toString)
		])
		
	}

really ,I am very confised :( Sad

Hence I allready duplicate name check with NamesAreUniqueValidator.My aim is:remove fields that has same type and same name in the View's ownedFields
(such as There are two Lookup field ,must get one lookupfield)

it does not take care about the scope of all possibilites.

I must do this for qualifiedname : if I override qualifiedname ,not do it .certainly ,I must do ?

@Inject

QualifiedName qualifiedName(Field f) {
System.out.println("******"+f.getName());
return qnc.toQualifiedName(f.getName());

Hi,
I used this code and duplicate names are remove.
but I use for field qualifiedname : overridequalifiedname screenshot

@Inject
			IQualifiedNameConverter qnc;

			QualifiedName qualifiedName(Field f) {
				System.out.println("******"+f.getName());
				return qnc.toQualifiedName(f.getName());
			}

if I do not use QualifiedName qualifiedName(Field f),result screenshot:withoutqualifiednameoverride:gets all field.

must I use IQualifiedNameConverter qnc?

Or you have to adapt the filter logic so that it uses qualified names
for the already applied fields

(By asking iqualifiednsmeprovider for the name instead field?.name

Hence if I used this code in the DefaultDeclarativeQualifiedNameProvider


public class QNP extends DefaultDeclarativeQualifiedNameProvider{
            @Inject
			IQualifiedNameConverter qnc;

			QualifiedName qualifiedName(Field f) {
				
				return qnc.toQualifiedName(f.getName());
			}
}

my below code works :

class MyDsl2ProposalProvider extends AbstractMyDsl2ProposalProvider {
	
	override completeViewField_Field(EObject model, Assignment assignment, ContentAssistContext context, ICompletionProposalAcceptor acceptor) {
		val view = EcoreUtil2::getContainerOfType(model, typeof(View))
		val names = view.ownedViewField.map[vw|vw.field?.name].filter[v|v!=null].toList
		println (names)
		lookupCrossReference(assignment.terminal as CrossReference, context, acceptor, [
			IEObjectDescription d | println(d.qualifiedName);!names.contains(d.qualifiedName)
		])
	}

vw.field?.name

Adds simple name

Inject Iqualifiednameprovider.
Ask it for the fields name.
Add the qualified name to the list

Hi do you want qualified names or not. It is always difficult to
find it out.

If you want them why did you post the name provider. If not why did
you change the proposal provider

Hi,

my problem is: i do not understand your problem.
i do not have a complete grammar. i do not have a test model.

from your posts i do not see what is the output of the println ("viewfielddddddddddddddd"+names)
and what is the output of the println(d.qualifiedName);

viewfielddddddddddddddd should give you all used names.
println(d.qualifiedName) should give you all names that you want to filter agains used names

if i have a model

CType ctx
	 			{
	 				fields {
	 					bf a bf b bf c
	 				}
	 			}
	 			 View v1 {
	 			 	
	 			 	fields
	 			 	= 
	 			 }

i get a b and c

if i have

CType ctx
	 			{
	 				fields {
	 					bf a bf b bf c
	 				}
	 			}
	 			 View v1 {
	 			 	
	 			 	fields
	 			 	= ctx.c, 
	 			 }

i get a and b

so it looks working to me

Hi Christian ,

I load my grammar ,I added View and ownedfield.
I load sample model screenshot.

My aim is : remove fields that has same name and same type ( such as text and lookup) for View's ownedfield
******gets onnly function's fields (function is upper from the View).hence Screenshot :

View V 's fields get onnly function F's defined fields (text ,lookup):
I load "myexample" screenshot .I marked yellow wanted field (get these fields)

Hence "type" has a "parent" tahat is a type.this type's fields must get.

I hope ,I explain my problem Sad

and How can I remove same type and same name .I use this code for remove duplicate name and same type. How can I do this

my util class.I can use this class in the scop class:

public static ArrayList<Field> returnUniqueParenListFields(View view){
		ArrayList<Field> allFields = returnAllParenListFields(view);
		
		for(int i = 0; i < allFields.size(); i++){
			Field field1 = allFields.get(i);
			
			for(int j = i+1; j < allFields.size(); j++){
				Field field2 = allFields.get(j);
			
				if(field1.eClass().getName().equals(field2.eClass().getName()) && field1.getName().equals(field2.getName())){
					allFields.remove(j);
					
				}
			}

		return allFields;

Hi,

I want to use my qualifiedname .I want to qualifiedname starts from the Method.

public class MQNP extends DefaultDeclarativeQualifiedNameProvider{
public static QualifiedName returnQualifiedNameOfElement(EObject object) {
String qualifiedName = "";
ArrayList<String> names = new ArrayList<String>();
while (object.eContainer() != null && !(object.eContainer() instanceof Collection)) {
if (object.eContainer() instanceof ContentextUnit)
names.add(((ContentextUnit) object.eContainer()).getName());
object = object.eContainer();
}

for (int i = names.size() - 1; i >= 0; i--) {
qualifiedName += names.get(i) + ".";
}

return QualifiedName.create(qualifiedName);
}
}

and I inject it in the scope class:


public class MyScoping extends AbstractDeclarativeScopeProvider {
	//@Inject IQualifiedNameProvider qnp;
	@Inject MQNP myqualified;
	
	IScope scope_Type_parentType(final Type ctx, EReference r) {
		final ArrayList<Type> possiblecontenttype = org.xtext.example.mydsl6.myDsl6.util.ContentTypeUtil.getPossibleParentContentType(ctx);
		
		//final ArrayList<Field> possiblefieldview = ViewUtil.possibleFieldForViewField(ctx) ;
		//final ArrayList<Field> possiblefield = LookUpUtil.returnSourceContentTypeNotLookUpFields(ctx);
		
		return Scopes.scopeFor( possiblecontenttype, myqualified, IScope.NULLSCOPE);
		
		
	}

my util class I shared before it :

public class ContentTypeUtil {
public static boolean isContentTypeParentOk(Type contentSource, Type contentTarget){
if(contentSource.equals(contentTarget)){
return false;
}
return true;
}

public static ArrayList<Type> getPossibleParentContentType(Type content){

Method web = ((Method)((Function)content.eContainer()).eContainer());
while(web.eContainer().eClass().getName().equals("Web")){
web = (Method) web.eContainer();
}
ArrayList<Type> allContentTypes = new ArrayList<>();

allContentTypes = returnAllContentTypeFromGivenWeb(web, allContentTypes);

allContentTypes.remove(content);

return allContentTypes;
}

public static ArrayList<Type> returnAllContentTypeFromGivenWeb(Method rootWeb, ArrayList<Type> returnAllContentTypesFromWeb){

EList<Function> ownedLists = rootWeb.getList();
for (Iterator<Function> iterator = ownedLists.iterator(); iterator.hasNext() Wink

I want to usequalifidname everywhere.My util class ,I post it.My aim is use it hence I want to start qualifiedname from Method .MQNP class is not work :( Sad

I want to use it for qualifiedname.I do not want to start with Context.

such as :

parent = CT.A.collection.M.F.T1 :I do not want
I am wanted :M.F.T1
such as :
View V {
type = "Type" fields =M.F.T.text
}


context CT  {
	Application A {
		Collection  collection {
			method M {
				function F {
					type T { parent = CT.A.collection.M.F.T1
						fields {
							Text text {
								displayName = "displayName" property = "Property"
							}
							Text created {
								displayName = "displayName" property = "Property"
							}
							Text createdby {
								displayName = "displayName" property = "Property"
							}
							LookUp Look {
								type = T showField = created
							}
							
						} 
					}type T1 {
					
						fields {
							Text created {
								displayName = "displayName" property = "Property"
								}
								Text createdby {
								displayName = "displayName" property = "Property"
							}
							Text created {
								displayName=" ewfg" property= "Property"
							}
						}
					}View V {
						 type = "Type" fields =CT.A.collection.M.F.T.text
					}
				} function F1 {
					type T2 {  parent =CT.A.collection.M.F.T
						fields {
							Text created {
								displayName = "displayName" property = "Property"
							}
						   Text created {
							
								displayName = "displayName" property = "Property"
						}
						Text look2{
							displayName = "displayName" property = "Property"}	
							
							Text text2{
							displayName = "displayName" property = "Property"}	
						}
					}type  T3 {
						fields {
							Text t3333 {
								displayName = "displayName" property = "Property"}
								
								Text t3333 {
								displayName = "displayName" property = "Property"}
								
								Text text2 {
								displayName = "displayName" property = "Property"
							}
						}
						
					}
					
					
					View Viweww {
						type = "Type"  fields =CT.A.collection.M.F1.T3.t3333

Sorry i cannot reproduce that

public class MyQNP extends DefaultDeclarativeQualifiedNameProvider {

	@Inject IQualifiedNameConverter qnc;
	
	QualifiedName qualifiedName(Function f) {
		return qnc.toQualifiedName(f.getName());
	}
}

class MyDsl6ScopeProvider extends AbstractDeclarativeScopeProvider {

	@Inject IQualifiedNameProvider qnp

	def IScope scope_ViewField_field(Function v, EReference ref) {
		Scopes::scopeFor(v.type.map[fields].flatten, qnp, IScope::NULLSCOPE)
	}
	
	def List<Field> getFields(Type t) {
		val res = <Field>newArrayList()
		res.addAll(t.ownedField)
		if (t.parentType != null) {
			res.addAll(getFields(t.parentType))

		res

Hi Christian ,

I solved my qualifiedname problem with return qnc.toQualifiedName(f.getName());
but I do not use my util class :( Sad

.My aim is start with in the Method for this code provide in the GMF part.so I want to use it .I want to explain it onlly.

public class MQNP extends DefaultDeclarativeQualifiedNameProvider{
public static QualifiedName returnQualifiedNameOfElement(Function object) {
String qualifiedName = "";
ArrayList<String> names = new ArrayList<String>();
while (object.eContainer() != null && !(object.eContainer() instanceof Collection)) {
if (object.eContainer() instanceof ContentextUnit)
names.add(((ContentextUnit) object.eContainer()).getName());
object = (Function) object.eContainer();
}

for (int i = names.size() - 1; i >= 0; i--) {
qualifiedName += names.get(i) + ".";
}

return QualifiedName.create(qualifiedName);
}
}

Sorry i have no ideas on Xtext/GMF Integration so i cannot give any advice in this direction.
returnQualifiedNameOfElement will not help you if nobody calls it.

you have either to fulfil the contract of DefaultDeclarativeNameProvider or IQualifiedNameProvider

Hi Christian,

I will create a new topic for qualifiedname.

I want to call returnQualifiedNameOfElement for View's ownedfields and Lookup's Showfield.

Hi Christian,

I start my qualifiedname with Method .but My Method rule is recursive.hence if I define one Method ,below code (return qnc.toQualifiedName(f.getName())) return second Method name.How can I solved this.
I want to fields =M. M1.F.T1.created for every referenced name.
such as :


method M {
				method M1{
				function F {
					type T { 
						
						fields {
							Text text {
								
								displayName = "displayName" property = "Property"
							}
							Text created {
								displayName = "displayName" property = "Property"
							}
							Text createdby {
								displayName = "displayName" property = "Property"
							}
							LookUp Look {
								type = T showField = created
							}
							
						} 
					}type T1 {
					
						fields {
							Text created {
								displayName = "displayName" property = "Property"
								}
								Text createdby {
								displayName = "displayName" property = "Property"
							}
							Text created {
								displayName=" ewfg" property= "Property"
							}
						}
					}View V {
						 type = "Type" fields = M1.F.T1.created
					}
				}

You need to traverse up the eContainer() of the Function F to get to the
Method M1, and the eContainer() of that Method to get to Method M.
You'll need to cast the returned value from eContainer() to the correct
type. From that information you can compose a qualified name.

Hi Ed,

I write qualifiedname util class for my GMF project.Now I want to use it in the Xtext part.but I do not use it .My aim is use this class in the qualifiednameprovider class.

public class QualifiedNameUtil {
	public static String returnQualifiedNameOfElement(EObject object) {
		String qualifiedName = "";
		ArrayList<String> names = new ArrayList<String>();
		while (object.eContainer() != null && !(object.eContainer() instanceof SiteCollection)) {
			if (object.eContainer() instanceof ContentUnit)
				names.add(((ContentUnit) object.eContainer()).getName());
				object = object.eContainer();
		}

		for (int i = names.size() - 1; i >= 0; i--) {
			qualifiedName += names.get(i) + ".";
		}

		return qualifiedName;
	}
}

besr regards

Your question was about something that as nested Method and function
instances. I see nothing in this code that deals with such cases. I
don't even see how the code you show below produces a name that doesn't
end with a ".". Shouldn't you use a StringBuilder for composing a string?

Hi Ed,

I think ,I can not use my util class.

I write a code now but recursive Method part .I cant do this part.I don t traverse in the Method
Below code result is :

View Viweww {
type = "Type" fields =M.F1.T2.created }
I dont get M1 Sad


QualifiedName qualifiedName( Function object) {
		String qualifiedName = "";
		ArrayList<String> names = new ArrayList<String>();
		Method w = (Method) object.eContainer();
		System.out.println(w);
		
		if( w.eContainer() instanceof Web){
		    Method w1 =(Method) w.eContainer();
		    
		System.out.println(w1);
		return QualifiedName.create(w1.getName(),object.getName()) ;
		}else		
		return QualifiedName.create(w.getName(),object.getName()) ;
	}

and I try this (below) code result :View Viweww {
type = "Type" fields = M.M1.F1.T2.created}
}

I am wanted is this,but I receive an error :( Sad

couldun't resolve reference .What is the my error Sad

QualifiedName qualifiedName( Function object) {
String qualifiedName = "";
ArrayList<String> names = new ArrayList<String>();
Method w = (Method) object.eContainer();
System.out.println(w);

if( w.eContainer() instanceof Method){
Method w1 =(Web) w.eContainer();
qualifiedName = w1.getName().concat(".").concat(w.getName()) ;
System.out.println(w1);
return QualifiedName.create(w1.getName().concat(".").concat(w.getName()),object.getName()) ;
}else

return QualifiedName.create(w.getName(),object.getName()) ;
}

Clearly if you call create name with only two arguments you won't get a
qualified name with three parts.

Hi Ed,

Hence I must to use one retun qualifiedname ?

in addition,I want to ask one question.I use different qualifiedname for different object,such as,I want to use two kind of qualifiedname in my project

If you want a three part name, you'll have to specify all three parts,
which you're not doing.

I find it incredible that you can drag on a thread like this endlessly.
And no, creating a new thread doesn't help. It's really as if you need
someone else to do the work for you. Even the most basic things you
spelled out in excruciating detail. In the end, no one has the patience
for such things, though I must say Christian is incredibly patient (or
rather persistent).
