Server classes for handling complicated graphs of model objects.

See: Description

Interface Summary

Interface	Description
GraphPolicyRulePredicate	A plug-in for graph policy rule matches whereby an object may be matched against named values.
GraphTraversal.PlanExecutor	Executor that allows callers to actually perform the planned action.
GraphTraversal.Processor	Executes the planned operation.

Class Summary

Class	Description
GraphPathBean	The graph path bean holds the Hibernate object mapping and assists navigation thereof.
GraphPathReport	A standalone tool for producing a summary of the Hibernate object mapping for our Sphinx documentation.
GraphPolicy	A policy guides how to traverse the graph.
GraphPolicy.Details	A tuple noting the state of a mapped object instance in the current graph traversal.
GraphPolicyRule	A graph policy rule specifies a component of a GraphPolicy.
GraphTraversal	An alternative implementation of model object graph traversal, relying on SELECTing in advance for making decisions, instead of rolling back to savepoints to recover from failed attempts to act.
GroupPredicate	A predicate that allows group=system and similar to be used in graph policy rule matches.
ModelObjectSequencer	OMERO model objects sometimes must be processed in a specific order.
PermissionsPredicate	A predicate that allows perms=rwr--- and similar to be used in graph policy rule matches.

Enum Summary

Enum	Description
GraphPolicy.Ability	Abilities that the user may have to operate upon model objects.
GraphPolicy.Action	The action to take on an object instance.
GraphPolicy.Orphan	If an object instance has any GraphPolicy.Action.EXCLUDEd parents that would prevent it from being orphaned.

Exception Summary

Exception	Description
GraphException	Exception which will be thrown by traversing the graph if an error occurred.
