Package y.view.hierarchy

Provides classes and interfaces for managing and viewing graph hierarchies (a.k.a. hierarchically organized graphs) where nodes can be nested within other nodes to arbitrary depth.

Description

Interface Summary

AutoBoundsFeature	Additional interface for node realizers whose bounds may be determined by other factors then explicit bound assignment.
HierarchyListener	The listener interface for receiving HierarchyEvents.
HierarchyManager.NodeVisitor	Callback interface that allows to perform some action when nodes within the hierarchy get visited in a certain order.
InterEdgeConfigurator	Callback interface that is used by class HierarchyManager whenever the state of an edge/interedge changes.

Class Summary

DefaultHierarchyGraphFactory	This is the default graph factory used by HierarchyManager to create and configure new graph elements within the hierarchy.
DefaultInterEdgeConfigurator	This default implementation of the InterEdgeConfigurator performs some simple heuristics.
DefaultNodeChangePropagator	This Graph2DListeners translates incoming Graph2DEvents that signal node label changes to hierarchy events that signal node changes.
Graph2DHierarchyClipboard	Provides clipboard functionality for diagrams that are hierarchically organized by a HierarchyManager instance.
Graph2DHierarchyUndoManager	This class provides undoability and redoability support for a hierarchy of graphs.
GroupLayoutConfigurator	This convenience class helps to prepare a hierarchically grouped Graph2D for an automatic assignment of layout information.
GroupNodeRealizer	A node realizer that is crafted to represent group and folder nodes within a graph hierarchy.
GroupNodeRealizer.StateChangeListener	This static inner class can be used to automatically adjust the groupClosed property of GroupNodeRealizer instances.
HierarchyCreateEdgeMode	A specialized CreateEdgeMode suitable for graphs that contain groups nodes.
HierarchyEditMode	A specialized EditMode suitable for editing hierarchically organized graphs.
HierarchyEvent	Encapsulates information describing changes to a graph hierarchy and used to notify hierarchy listeners of the change.
HierarchyHotSpotMode	A specialized HotSpotMode suitable for editing hierarchically organized graphs.
HierarchyJTree	A JTree configured to display the hierarchically organized nodes within a HierarchyManager.
HierarchyManager	This class manages a hierarchy of grouped nodes and nested graphs.
HierarchyMoveSelectionMode	A specialized MoveSelectionMode suitable for graphs that contain group nodes.
HierarchySelectionBoxMode	A specialized SelectionBoxMode suitable for graphs that contain group nodes.
HierarchyTreeCellRenderer	Default TreeCellRenderer to visualize elements within HierarchyTreeModel.
HierarchyTreeModel	This class represents a tree model view of a graph hierarchy managed by HierarchyManager.
HierarchyTreeSelectionModel	This TreeSelectionModel represents the selection state of the nodes within a graph hierarchy.
HierarchyTreeTransferHandler	A transfer handler for HierarchyJTree that allows to reorganize the hierarchical group structure by a drag and drop gesture on the tree elements.
ProxyAutoBoundsNodeRealizer	A proxy node realizer that implements the auto bounds feature.

Package y.view.hierarchy Description

Provides classes and interfaces for managing and viewing graph hierarchies (a.k.a. hierarchically organized graphs) where nodes can be nested within other nodes to arbitrary depth.

Most prominent class of this package is HierarchyManager. It adds support for grouping and nesting to a yet "flat" graph, and maintains the model that is behind graph hierarchies.
Further classes provide functionality that extend corresponding classes from package y.view to suit the specialized needs of hierarchically organized graphs.
