Class XorFilter

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, NodeFilter
    public class XorFilter
extends java.lang.Object
implements NodeFilter
    Accepts nodes matching an odd number of its predicates filters (XOR operation). For example, where it has two filters, it accepts only if and only if one of the two filters accepts the Node, but does not accept if both filters accept the Node.
