Constructor Detail

NodeCopier

NodeCopier(java.lang.String srcBase,
           Remapper destination,
           java.lang.String dstBase,
           boolean recursive)

Construct an instance of NodeCopier for specified source ID, destination ID and back-end.

Parameters:

srcBase - Node ID for the root of the source subtree.

destination - Reference to the destination back-end.

dstBase - Node ID for the root of the new subtree

recursive - true enables recursive copying. Otherwise copying will be stopped after first copy operations.

Method Detail

visit

public java.lang.Object visit(Remapper service,
                              java.lang.String nodeId)

Implementation of the NodeProcessor interface. This method copies node specified by the nodeId from back-end referenced by service parameter into destination back-end.

Specified by:

visit in interface NodeProcessor

Parameters:

service - Remapper instance which is traversed

nodeId - Node Id

Returns:

An object instance if tree traversal should be stopped or null to continue operation.
