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,
                            Map nodeMap,
                            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 Object createNodeId(Object srcId,
                              Node dst)

Factory method that creates an id for the given node. This implementation uses the destination node itself as the id for the node.
