Class MergePoint

java.lang.Object
  org.broadleafcommerce.common.extensibility.context.merge.MergePoint

public class MergePoint
extends Object

This class provides the xml merging apparatus at a defined XPath merge point in 2 xml documents. The MergeHandler that embodies the XPath point can have embedded XPath merge points, resulting in a cumulative effect with varying merge behavior for a sector of the documents. For example, it may be desirable to replace all the child nodes of a given node with all the child nodes from the same parent node in the patch document, with the exception of a single node. That single node may instead contribute its contents in a additive fashion (rather than replace).
