java.lang.Object
org.jbpm.util.client.Relations
- public class Relations
- extends java.lang.Object
specifies which related objects should be resolved for data-transfer-objects,
returned from a session-facade.
A session facade is supposed to collect data from the persistency-layer
and return data-transfer-objects to the client. If the datamodel has a lot
of relations, a problem arises : Which related objects should be resolved in
the object that is returned to the client. A Relations-object is a convenient way of specifying
which related objects you want to be resolve on the objects returned by the session facade.
You can specify these Relations with dot-separated property-names.
E.g. if the returned object is a Flow, "attributeInstance.attribute" specifies that
for every returned Flow-object the methods Collection getAttributeInstance() must
be resolved and that these AttributeInstances have the Attribute getAttribute()
resolved.
