Class GraphCopyFactory

java.lang.Object
  y.base.GraphCopyFactory

All Implemented Interfaces:

GraphCopier.CopyFactory

public class GraphCopyFactory
extends java.lang.Object
implements GraphCopier.CopyFactory

Very simple default implementation of a Copy Factory that creates Graph instances and simply delegates to the Graph.createNode() and Graph.createEdge(Node, Node) method.

Constructor Summary

GraphCopyFactory()

Method Summary

Edge	copyEdge(Graph targetGraph, Node source, Node target, Edge originalEdge) Copies the originalEdge from the source graph to the new targetGraph using the specified new source and target node in the target graph.
Node	copyNode(Graph targetGraph, Node originalNode) Copies the originalNode from the source graph to the new targetGraph
Graph	createGraph() Creates a new Graph.
void	postCopyGraphData(Graph originalGraph, Graph newGraph, java.util.Map nodeMap, java.util.Map edgeMap) This implementation does nothing.
void	preCopyGraphData(Graph hint, Graph newGraph) This implementation does nothing.

Method Detail

preCopyGraphData

public void preCopyGraphData(Graph hint,
                             Graph newGraph)

This implementation does nothing.

Specified by:

preCopyGraphData in interface GraphCopier.CopyFactory

Parameters:

hint - the graph that will be used to copy the entities from.

newGraph - the graph that will be used to copy the entities to.

postCopyGraphData

public void postCopyGraphData(Graph originalGraph,
                              Graph newGraph,
                              java.util.Map nodeMap,
                              java.util.Map edgeMap)

This implementation does nothing.

Specified by:

postCopyGraphData in interface GraphCopier.CopyFactory

Parameters:

originalGraph - the graph that was used to copy the entities from.

newGraph - the graph that was used to copy the entities to.

nodeMap - a map that contains a mapping between the nodes in the source graph to their corresponding nodes in the new graph.

edgeMap - a map that contains a mapping between the edges in the source graph to their corresponding edges in the new graph.

copyNode

public Node copyNode(Graph targetGraph,
                     Node originalNode)

Description copied from interface: GraphCopier.CopyFactory

Copies the originalNode from the source graph to the new targetGraph

Specified by:

copyNode in interface GraphCopier.CopyFactory

Parameters:

targetGraph - the graph to create the new node in

originalNode - the original node from the source graph

Returns:

the newly created node

copyEdge

public Edge copyEdge(Graph targetGraph,
                     Node source,
                     Node target,
                     Edge originalEdge)

Description copied from interface: GraphCopier.CopyFactory

Copies the originalEdge from the source graph to the new targetGraph using the specified new source and target node in the target graph.

Specified by:

copyEdge in interface GraphCopier.CopyFactory

Parameters:

targetGraph - the graph to create the new node in

source - the source node in the target graph to use for the newly created edge

target - the target node in the target graph to use for the newly created edge

originalEdge - the original edge from the source graph

Returns:

the newly created edge

createGraph

public Graph createGraph()

Creates a new Graph.

Specified by:

createGraph in interface GraphCopier.CopyFactory

Returns:

the graph to use as the target graph
