extends java.lang.Object

implements java.util.Comparator

Constructor Summary

KeyedReferenceComparatorForCategoryBag()

Method Summary

int	compare(java.lang.Object obj1, java.lang.Object obj2) Takes two KeyedReference objects and returns 0 if and only if they are equal by the semantics of this type of comparator (see details below).
boolean	equals(java.lang.Object obj) Returns true if and only if the parameter object is a Comparator that imposes the same equality/ordering as this Comparator.

Method Detail

compare

public int compare(java.lang.Object obj1,
                   java.lang.Object obj2)

Takes two KeyedReference objects and returns 0 if and only if they are equal by the semantics of this type of comparator (see details below). If they are not equal, returns -1. Note that this behavior differs from the general contract of java.util.Comparator intentionally. We do not care about ordering the objects, just about object equality.

Equality semantics: There are two cases to consider for keyedReferences contained within categoryBags. If the tModel key represents the special "general_keywords" builtin category, then kr1 and kr2 are equal if and only if: (kr1.tModelKey == kr2.tModelKey) && (kr1.keyValue == kr2.keyValue) && (kr1.keyName == kr2.keyName). For any other tModel key, kr1 and kr2 are equal if and only if: (kr1.tModelKey == kr2.tModelKey) && (kr1.keyValue == kr2.keyValue).

equals

public boolean equals(java.lang.Object obj)
