java.lang.Object y.io.graphml.graph2d.HierarchyManagerBasedGraphElementFactory
public class HierarchyManagerBasedGraphElementFactory
Implementation of the GraphElementFactory
interface that can create HierarchyManager
based hierarchy information.
If a HierarchyManager
instance is registered on the graph
that is populated, it is used to create the hierarchy information. The actual creation
of normal nodes is delegated to a customizable implementation.
Constructor Summary | |
---|---|
HierarchyManagerBasedGraphElementFactory()
Create a new instance with a getCoreFactory() set to a Graph2DElementFactory |
|
HierarchyManagerBasedGraphElementFactory(GraphElementFactory coreFactory)
Create a new instance with a custom getCoreFactory() . |
Method Summary | |
---|---|
Edge |
createEdge(GraphMLParseContext context,
Node sourceNode,
Port sourcePort,
Node targetNode,
Port targetPort)
Creates an edge for the given context and the provided source and target nodes or ports. |
Node |
createNode(GraphMLParseContext context)
Creates a node for the given context. |
Port |
createPort(GraphMLParseContext context,
Node owner)
Creates a port object that is owned by owner |
protected void |
edgeCreated(Graph graph,
Edge edge,
CreationProperties properties)
Notifies interested parties that an edge was created. |
protected void |
folderCreated(Graph graph,
Node node,
CreationProperties properties)
Notifies interested parties that a folder node was created. |
GraphElementFactory |
getCoreFactory()
Returns the core factory for creation of normal nodes and edges. |
protected Node |
getParent(GraphMLParseContext context)
Retrieves the parent node for new nodes. |
protected void |
groupCreated(Graph graph,
Node node,
CreationProperties properties)
Notifies interested parties that a group node was created. |
protected void |
nodeCreated(Graph graph,

public HierarchyManagerBasedGraphElementFactory()
getCoreFactory()
set to a Graph2DElementFactory
public HierarchyManagerBasedGraphElementFactory(GraphElementFactory coreFactory)
getCoreFactory()
.
It is the users responsibility to set up the HierarchyManager
to work
correctly with non Graph2D
instances.
