public LayoutGraphCopyFactory()

Method Detail

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

copyLabels

protected void copyLabels(LayoutGraph originalLayoutGraph,
                          Node originalNode,
                          LayoutGraph targetGraph,
                          Node newNode)

Callback that copies the labels for a given node.

copyNodeLabelLayout

protected NodeLabelLayout copyNodeLabelLayout(NodeLabelLayout nodeLabelLayout)

Copies the node label's layout.

copyEdge

public Edge copyEdge(Graph targetGraph,
                     Node newSource,
                     Node newTarget,
                     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

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

newTarget - 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 DefaultLayoutGraph.

Specified by:

createGraph in interface GraphCopier.CopyFactory

Returns:

the graph to use as the target graph

copyLabels

protected void copyLabels(LayoutGraph originalLayoutGraph,
                          Edge originalEdge,
                          LayoutGraph layoutGraph,
                          Edge edge)

Callback that copies the labels for a given edge.

copyEdgeLabelLayout

protected EdgeLabelLayout copyEdgeLabelLayout(EdgeLabelLayout edgeLabelLayout)

Copies the edge label's layout.

preCopyGraphData

public void preCopyGraphData(Graph originalGraph,
                             Graph newGraph)

Description copied from interface: GraphCopier.CopyFactory

Callback that will be called before the copy operation takes place. At that point in time no entities have been copied to the new graph.

Specified by:

preCopyGraphData in interface GraphCopier.CopyFactory

Parameters:

originalGraph - 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,
                              Map nodeMap,
                              Map edgeMap)

Description copied from interface: GraphCopier.CopyFactory

Callback that will be called after the copy operation has completed. At that point in time all entities have been copied to the new graph.

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.
