Inherited from:
IdentifiableType<X>
Since:
JPA 2.0
SingularAttribute<X,Y> getDeclaredVersion(Class<Y> type)
Return the attribute that corresponds to the version attribute declared by the entity or mapped superclass.
Parameters:
type - the type of the represented declared version attribute
Return:
declared version attribute
Throws:
IllegalArgumentException - if version attribute of the type is not declared in the identifiable type

IdentifiableType<X>
Since:
JPA 2.0
SingularAttribute<?superX,Y> getId(Class<Y> type)
Return the attribute that corresponds to the id attribute of the entity or mapped superclass.
Parameters:
type - the type of the represented id attribute
Return:
id attribute
Throws:
IllegalArgumentException - if id attribute of the given type is not present in the identifiable type or if the identifiable type has an id class
Inherited from:
IdentifiableType<X>
Since:
JPA 2.0
Set<SingularAttribute<?superX,?>> getIdClassAttributes()
Return the attributes corresponding to the id class of the identifiable type.
Return:
id attributes
Throws:
