All Implemented Interfaces:

Comparable<Object>, MergeHandler

Direct Known Subclasses:

LiberalNodeReplaceInsert, MetadataOverrideNodeReplaceInsert, NodeReplace, NonEmptyNodeReplaceInsert

public class NodeReplaceInsert
extends BaseHandler

This handler is responsible for replacing nodes in the source document with the same nodes from the patch document. Note, additional nodes from the patch document that are not present in the source document are simply appended to the source document.

Method Details

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

exhaustedNodesContains

protected boolean exhaustedNodesContains(List<Node> exhaustedNodes,
 Node node)

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)

replaceCeilingEntityNode

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

special "replace" method for metatataOverride items having the "ceilingEntity" attribute specified. Instead of just overwriting a previously specified item, successive overrideItems with the same ceilingEntity are "merged" into the previous one; the resulting node contains the logical union of both old and new children

Parameters:

primaryNodes -

testNode -

usedNodes -

Returns:
