LazyEntityResolver
==================

.. java:package:: org.caosdb.server.jobs
   :noindex:

.. java:type:: public class LazyEntityResolver extends EntityWrapper

   Implementation of \ :java:ref:`EntityInterface`\  which retrieves the parents and properties only when requested via getProperties and getParents.

   This is particularly useful for jobs sharing the same entity object between jobs which need different parts of it while reducing the logic of checking whether the entity is "only" sparse, or has been retrieved fully and so on.

   However, when the entities parents or properties are being retrieved after the transaction's access has been released, an \ :java:ref:`IllegalStateException`\  will be thrown.
