public class PortableESPK
extends java.lang.Object
implements ESPK, java.lang.Comparable<PortableESPK>, com.vordel.common.Dictionary

Implementation of a portable or 'provider-neutral' ESPK. This ESPK can be used to identify specific Entities in any given entity store, based on their key field values. It is used specifically for importing/exporting data and for comparing Entities between two stores.
