Class Triple<T0,T1,T2>

java.lang.Object
  mondrian.util.Triple<T0,T1,T2>

All Implemented Interfaces:

Comparable<Triple<T0,T1,T2>>

public class Triple<T0,T1,T2>
extends Object
implements Comparable<Triple<T0,T1,T2>>

Tuple of three values.

Because a triple implements equals(Object), hashCode() and compareTo(mondrian.util.Triple), it can be used in any kind of Collection.
