All Implemented Interfaces:

Serializable, Pattern

public class CutTreePattern
extends TreePattern

A Pattern in which prune(Node) removes all the edges of matching nodes, not only those that are not required for matching.

This pattern minimises the amount of matching data returned by prune(Node) when the properties of the data are not required for further processing (e.g. when matching elements need only to be counted).
