Class Members.Member<X,Y>

java.lang.Object
  extended by org.apache.openjpa.persistence.meta.Members.Member<X,Y>
Type Parameters:
X - The type that contains this attribute
Y - The type of this attribute
All Implemented Interfaces:
Comparable<Members.Member<X,Y>>, Attribute<X,Y>
Direct Known Subclasses:
Members.PluralAttributeImpl, Members.SingularAttributeImpl
Enclosing class:
Members

public abstract static class Members.Member<X,Y>
extends Object
implements Attribute<X,Y>, Comparable<Members.Member<X,Y>>

An attribute of a Java type. A persistent attribute is realized as a field and getter/setter method of a Java class. This implementation adapts kernel's FieldMetaData construct to meet the JPA API contract.
