Gaurav,
To use indirection set:
oneToOneMapping.useBasicIndirection()
Also, read and write transformers are used and specified on a
TransformationMapping. Not sure I completely understand your
question and their usage with the attribute accessor. The accessor
is used to retrieve the value from the object into the mapping.
The mapping can then apply any transformations or conversions.
When using a DirectToFieldMapping you could use a converter on the
mapping.
Cheers,
Guy

Hi All, I am trying to specify DirectToFieldMapping, OneToMapping
and OneToManyMapping in the session customizer. Let's take a
example of OneToOneManyMapping . I am setting up the
OneToOneMapping as follows. Currently I am specifying "do not use
indirection". Is it possible to specify - IndirectionPolicy and
make sure the relationship uses ValueHolder (lazy initialization).
I will be great if somebody can point me to sample code to achieve
this.I want to programatically weave in the lazy loading value
holder code. private void oneToOneMapping(ClassDescriptor
classDescriptor) { OneToOneMapping _oneToOneMapping_ = new
OneToOneMapping(); oneToOneMapping.setDescriptor(classDescriptor);
oneToOneMapping.setCascadeAll(true);
oneToOneMapping.dontUseIndirection();
VirtualAttributeAccessor virtualAttributeAccessor2 = new
VirtualAttributeAccessor();
virtualAttributeAccessor2.setAttributeName("phoneNumber");
virtualAttributeAccessor2.setGetMethodName("get");
virtualAttributeAccessor2.setSetMethodName("set");
virtualAttributeAccessor2.initializeAttributes(classDescriptor.getJavaClass());
oneToOneMapping.setAttributeAccessor(virtualAttributeAccessor2);
oneToOneMapping.setAttributeName("phoneNumber");
oneToOneMapping.setReferenceClass(PhoneNumber.class);
oneToOneMapping.setForeignKeyFieldName("PHONE_NUMBER_ID"); Vector
databaseFields = new Vector();
databaseFields.add("PHONE_NUMBER_ID");
oneToOneMapping.setForeignKeyFieldNames(databaseFields);
classDescriptor.getMappings().add(oneToOneMapping); }
Another question
=============
Is it possible to specify Reader/WriterTrasnformer with
VirtualMethods. That is, to apply Reade/WriteTransformer to
the attributes in the extension Map. NOTE > In my use case,
extension attributes can be
DirectToFieldMapping/OneToOne/OneToMany attributes which I am
making it programatically in the session customization phase.
