Package org.eclipse.persistence.internal.descriptors

Class MethodAttributeAccessor

java.lang.Object

org.eclipse.persistence.mappings.AttributeAccessor

org.eclipse.persistence.internal.descriptors.MethodAttributeAccessor

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, CoreAttributeAccessor

Direct Known Subclasses:

VirtualAttributeAccessor

public class MethodAttributeAccessor
extends AttributeAccessor

Purpose: A wrapper class for handling cases when the domain object attributes are to be accessed thru the accessor methods. This could happen if the variables are not defined public in the domain object.

Since:

TOPLink/Java 1.0
