defaultOperations - the operations permitted for the EntityManager remote service

manageAllEntities - whether all entities should be managed by Pimento, even if no Managed annotation is present

Returns:

metadata instances for all managed persistent entities

isUninitializedProxy

boolean isUninitializedProxy(Object entity)
