Constructor Detail

SessionNode.DeepCopy

protected SessionNode.DeepCopy(SessionNode targetNode,
                               WritableSessionCache cache,
                               CachedNode sourceNode,
                               SessionCache sourceCache)

Method Detail

getSourceToTargetKeys

public Map<NodeKey,NodeKey> getSourceToTargetKeys()

execute

public void execute()

doPhase1

protected void doPhase1(MutableCachedNode targetNode,
                        CachedNode sourceNode)

Perform a copy of the source tree to create a similar tree in the target session. Note that copying linked nodes varies depending upon where the linked nodes are relative to the source tree.

1. If the linked nodes and the original node are all in the source tree being copied, then the result of the copy will contain a copy of the original and links to the new copy.
2. If the original node is not within the source tree being copied, then the result of the copy will contain links to the original node.

The result of phase 1 will have either created the links correctly or will have add placeholders in the target tree representing where the linked children should exist. Such placeholders will be handled in phase 2.

Parameters:

targetNode - the (empty) target node that should be made to look like the supplied source node; may not be null

sourceNode - the original node that should be copied; may not be null

createTargetKeyFor

protected NodeKey createTargetKeyFor(NodeKey sourceKey,
                                     NodeKey parentKeyInTarget)

doPhase2

protected void doPhase2()

This leaves any linked placeholders that failed in the map.

copyProperties

protected void copyProperties(MutableCachedNode targetNode,
                              CachedNode sourceNode)

toString

public String toString()

Overrides:

toString in class Object

getOperationName

protected String getOperationName()
