Class MappedSuperclassTypeImpl<X>

java.lang.Object

org.eclipse.persistence.internal.jpa.metamodel.TypeImpl<X>

org.eclipse.persistence.internal.jpa.metamodel.ManagedTypeImpl<X>

org.eclipse.persistence.internal.jpa.metamodel.IdentifiableTypeImpl<X>

org.eclipse.persistence.internal.jpa.metamodel.MappedSuperclassTypeImpl<X>

Type Parameters:

X - The represented entity type

All Implemented Interfaces:

java.io.Serializable

public class MappedSuperclassTypeImpl<X>
extends IdentifiableTypeImpl<X>

Purpose: Provides the implementation for the MappedSuperclassType interface of the JPA 2.0 Metamodel API (part of the JSR-317 EJB 3.1 Criteria API)

Description: Instances of the type MappedSuperclassType represent mapped superclass types.

Since:

EclipseLink 1.2 - JPA 2.0

Constructor Detail

MappedSuperclassTypeImpl

protected MappedSuperclassTypeImpl(MetamodelImpl metamodel,
                                   ClassDescriptor relationalDescriptor)

Method Detail

addInheritingType

protected void addInheritingType(IdentifiableTypeImpl identifiableType)

INTERNAL: Add an inheriting subclass to the map of Identifiable types that inherit from this mappedSuperclass.

Parameters:

identifiableType -

create

protected static MappedSuperclassTypeImpl<?> create(MetamodelImpl metamodel,
                                                    ClassDescriptor relationalDescriptor)

INTERNAL: Return an instance of a MappedSuperclassType based on the RelationalDescriptor.

Parameters:

metamodel -

relationalDescriptor -

Returns:

getMemberFromInheritingType

public AttributeImpl getMemberFromInheritingType(java.lang.String name)

INTERNAL: MappedSuperclasses need special handling to get their type from an inheriting subclass. This function determines the type for an attribute by returning the same inherited attribute from a subclass

Parameters:

name -

Returns:

getPersistenceType

public javax.persistence.metamodel.Type.PersistenceType getPersistenceType()

Return the persistence type.

Returns:

persistence type

initialize

protected void initialize()

Description copied from class: ManagedTypeImpl

INTERNAL: Initialize the members of this ManagedType based on the mappings defined on the descriptor. We process the appropriate Map, List, Set, Collection or Object/primitive types.

Initialization should occur after all types in the metamodel have been created already.

Overrides:

initialize in class ManagedTypeImpl<X>

isEntity

public boolean isEntity()

INTERNAL: Return whether this type is an Entity (true) or MappedSuperclass (false) or Embeddable (false)

Specified by:

isEntity in class TypeImpl<X>

Returns:

isMappedSuperclass

public boolean isMappedSuperclass()

INTERNAL: Return whether this type is an MappedSuperclass (true) or Entity (false) or Embeddable (false)

Specified by:

isMappedSuperclass in class TypeImpl<X>

Returns:
