@SupportedAnnotationTypes(value={"javax.persistence.Entity","javax.persistence.Embeddable","javax.persistence.MappedSuperclass"})
public class JPACriteriaProcessor
extends AbstractProcessor
Annotation processor for JPA to generate "dummy" classes for all Entity classes for use with Criteria API.
Any class ({MyClass}) that has a JPA "class" annotation will have a stub class ({MyClass}_) generated.
For each managed class X in package p, a metamodel class X_ in package p is created.
The name of the metamodel class is derived from the name of the managed class by appending "_"
to the name of the managed class.
The metamodel class X_ must be annotated with the javax.persistence.StaticMetamodel annotation
If class X extends another class S, where S is the most derived managed class (i.e., entity or
mapped superclass) extended by X, then class X_ must extend class S_, where S_ is the meta-model class
created for S.
For every persistent non-collection-valued attribute y declared by class X, where the type of y is Y,
the metamodel class must contain a declaration as follows:
public static volatile SingularAttribute y;
For every persistent collection-valued attribute z declared by class X, where the element type
of z is Z, the metamodel class must contain a declaration as follows:
if the collection type of z is java.util.Collection, then
public static volatile CollectionAttribute z;
if the collection type of z is java.util.Set, then
public static volatile SetAttribute z;
if the collection type of z is java.util.List, then
public static volatile ListAttribute z;
if the collection type of z is java.util.Map, then
public static volatile MapAttribute z;
where K is the type of the key of the map in class X
Convenience accessor for members for the default access type of the supplied type element.
If properties are annotated then returns all properties, otherwise returns all fields.
Parameters:
el - The type element
Returns:
The members
isJPAAnnotated
public static boolean isJPAAnnotated(TypeElement el)
Convenience method to return if this class element has any of the defining JPA annotations.
Parameters:
el - The class element
Returns:
Whether it is to be considered a JPA annotated class
