Class PluralAttributeImpl<X,C,V>

java.lang.Object

org.eclipse.persistence.internal.jpa.metamodel.AttributeImpl<X,C>

org.eclipse.persistence.internal.jpa.metamodel.PluralAttributeImpl<X,C,V>

Type Parameters:

X - The type the represented collection belongs to

C - The type of the represented collection

V - The element type of the represented collection

All Implemented Interfaces:

Attribute<X,C>, Bindable<V>, PluralAttribute<X,C,V>, Serializable

Direct Known Subclasses:

CollectionAttributeImpl, ListAttributeImpl, MapAttributeImpl, SetAttributeImpl

public abstract class PluralAttributeImpl<X,C,V>
extends AttributeImpl<X,C>
implements PluralAttribute<X,C,V>

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

Description: Instances of the type PluralAttribute represent persistent collection-valued attributes.
