handle

private static class handle.DummyResource
extends java.lang.Object
implements WrappedResource

A pseudo-resource with a set id. This type of resources should be used when retrieving handles from database records. In this case, if the handle is invalid, a dummy resource with a set id should be returned, instead of a "zero" resource. The "zero" resource is returned when explicitly converting strings to handles.
