com.sun.jdo.api.persistence.mapping.ejb.AbstractNameMapper

Direct Known Subclasses:

NameMapper

public abstract class AbstractNameMapper
extends Object

This is a class which helps translate between the various names of the CMP (ejb name, abstract schema, abstract bean, concrete bean, local interface, remote interface) and the persistence-capable class name. It also has methods for translation of field names. The basic entry point is ejb name or persistence-capable class name.
