All Implemented Interfaces:

GraphCopier.CopyFactory

Enclosing class:

LayoutGraphCopyFactory

public static class LayoutGraphCopyFactory.HierarchicGraphCopyFactory
extends GraphCopier.GraphDataCopyFactory

An implementation of the copy factory interface used by GraphCopier that can be used by implementations of LayoutGraph that are hierarchically grouped using GroupingKeys.

Constructor Summary

LayoutGraphCopyFactory.HierarchicGraphCopyFactory()
Creates new LayoutGraphCopyFactory.HierarchicGraphCopyFactory instance with default settings.

LayoutGraphCopyFactory.HierarchicGraphCopyFactory(GraphCopier.CopyFactory delegatingFactory)
Creates new LayoutGraphCopyFactory.HierarchicGraphCopyFactory instance that delegates to the passed factory.

Method Summary

protected void	copyData(Node src, Node dst) Empty stub to be overwritten by subclass implementations.
protected java.lang.Object	createNodeId(java.lang.Object srcId, Node dst) Creates an ID for the given node.
protected void	postCopyData(Graph src, Graph dst, java.util.Map nodeMap, java.util.Map edgeMap) Empty stub to be overwritten by subclass implementations.
protected void	preCopyData(Graph src, Graph dst) Empty stub to be overwritten by subclass implementations.

Constructor Detail

LayoutGraphCopyFactory.HierarchicGraphCopyFactory

public LayoutGraphCopyFactory.HierarchicGraphCopyFactory()

Creates new LayoutGraphCopyFactory.HierarchicGraphCopyFactory instance with default settings.

LayoutGraphCopyFactory.HierarchicGraphCopyFactory

public LayoutGraphCopyFactory.HierarchicGraphCopyFactory(GraphCopier.CopyFactory delegatingFactory)

Creates new LayoutGraphCopyFactory.HierarchicGraphCopyFactory instance that delegates to the passed factory.

Parameters:

delegatingFactory - the factory

Method Detail

preCopyData

protected void preCopyData(Graph src,
                           Graph dst)

Description copied from class: GraphCopier.GraphDataCopyFactory

Empty stub to be overwritten by subclass implementations.

Overrides:

preCopyData in class GraphCopier.GraphDataCopyFactory

postCopyData

protected void postCopyData(Graph src,
                            Graph dst,
                            java.util.Map nodeMap,
                            java.util.Map edgeMap)

Description copied from class: GraphCopier.GraphDataCopyFactory

Empty stub to be overwritten by subclass implementations.

Overrides:

postCopyData in class GraphCopier.GraphDataCopyFactory

nodeMap - a Map that maps old node instances to their new copies

edgeMap - a Map that maps old edge instances to their new copies

copyData

protected void copyData(Node src,
                        Node dst)

Description copied from class: GraphCopier.GraphDataCopyFactory

Empty stub to be overwritten by subclass implementations.

Overrides:

copyData in class GraphCopier.GraphDataCopyFactory

Parameters:

src - the old entity

dst - the new entity

createNodeId

protected java.lang.Object createNodeId(java.lang.Object srcId,
                                        Node dst)

Creates an ID for the given node.

This implementation uses the destination node itself as the ID for the node.

The method is called by copyData(Node, Node) and may be overridden to assign custom unique IDs.

Parameters:

srcId - the ID of the original node

dst - the copy of the original node

Returns:

the node ID which is the destination node itself
