Package org.eclipse.persistence.internal.jpa.deployment

Class URLArchive

java.lang.Object

org.eclipse.persistence.internal.jpa.deployment.ArchiveBase

org.eclipse.persistence.internal.jpa.deployment.URLArchive

All Implemented Interfaces:

Archive

public class URLArchive
extends ArchiveBase
implements Archive

This is an implementation of Archive when container returns a url that is not one of the familiar URL types like file or jar URLs. So, we can not recursively walk thru' its hierarchy. As a result getEntries() returns an empty collection.
