merge

public Node[] merge(List<Node> nodeList1,
           List<Node> nodeList2,
           List<Node> exhaustedNodes)

Description copied from interface: MergeHandler

Perform the merge using the supplied list of nodes from the source and patch documents, respectively. Also, a list of nodes that have already been merged is provided and may be used by the implementation when necessary.

Parameters:

nodeList1 - list of nodes to be merged from the source document

nodeList2 - list of nodes to be merged form the patch document

exhaustedNodes - already merged nodes

Returns:

list of merged nodes

checkNode

protected boolean checkNode(List<Node> usedNodes,
                Node[] primaryNodes,
                Node node)

exactNodeExists

protected boolean exactNodeExists(Node[] primaryNodes,
                      Node testNode,
                      List<Node> usedNodes)

replaceNode

protected boolean replaceNode(Node[] primaryNodes,
                  Node testNode,
                  String attribute,
                  List<Node> usedNodes)
