public interface ItemStateFactory

ItemStateFactory provides methods to create child NodeStates and PropertyStates for a given NodeState.

Method Summary

Modifier and Type	Method and Description
void	addCreationListener(ItemStateCreationListener listener) Adds the given ItemStateCreationListener.
NodeState	createDeepNodeState(NodeId nodeId, NodeEntry anyParent) Tries to retrieve the NodeState with the given NodeId and if the state exists, fills in the NodeEntries missing between the last known NodeEntry marked by anyParent.
PropertyState	createDeepPropertyState(PropertyId propertyId, NodeEntry anyParent) Tries to retrieve the PropertyState with the given PropertyId and if the state exists, fills in the HierarchyEntries missing between the last known NodeEntry marked by anyParent.
NodeState	createNodeState(NodeId nodeId, NodeEntry entry) Creates the child NodeState with the given nodeId.
PropertyState	createPropertyState(PropertyId propertyId, PropertyEntry entry) Creates the PropertyState with the given propertyId.
NodeState	createRootState(NodeEntry entry)
Iterator<ChildInfo>	getChildNodeInfos(NodeId nodeId) Returns an Iterator over ChildInfos for the given NodeState.
Iterator<PropertyId>	getNodeReferences(NodeState nodeState, Name propertyName, boolean weak) Returns the identifiers of all reference properties that point to the given node.
void	removeCreationListener(ItemStateCreationListener listener) Removes the given ItemStateCreationListener.
