java.lang.Object
  edu.neu.ccs.demeterf.lib.List.GComp<X,Y>

Direct Known Subclasses:

List.Comp

Enclosing class:

List<X>

public abstract static class List.GComp<X,Y>
extends java.lang.Object

(General) Compare two List Elements of possibly different types (true is "LessThan" for sort(), but "Equal" for same(...))

Constructor Summary

List.GComp()

Method Summary

abstract boolean	comp(X x, Y y) Compare these two Xs, returning true/false
List.Pred<X>	curry(Y y) Return a Predicate that uses the comparator (later) using the given X as its first argument
List.GComp<Y,X>	flip() Return a general comparator with flipped comparision (and types)
List.Pred<Y>	revCurry(X x) Return a (reversed) Predicate that uses the comparator (later) using the given Y as its second argument
