java.lang.Object
  org.hd.d.pg2k.svrCore.Tuple.ComparablePair<T1,T2>

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Tuple.ComparablePair<T1,T2>>

Enclosing class:

Tuple

public static final class Tuple.ComparablePair<T1 extends java.lang.Comparable<T1>,T2 extends java.lang.Comparable<T2>>
extends java.lang.Object
implements java.io.Serializable, java.lang.Comparable<Tuple.ComparablePair<T1,T2>>

A simple immutable Comparable pair (though the referenced items may be mutable). Either or both fields can be null.

Equality and hash are based on that of the two members.

The natural ordering given by compareTo() is determined by "first", with "second" breaking ties.

See Also:

Serialized Form

first

public final T1 extends java.lang.Comparable<T1> first

second

public final T2 extends java.lang.Comparable<T2> second

The second member of the pair.

Overrides:

equals in class java.lang.Object

compareTo

public int compareTo(Tuple.ComparablePair<T1,T2> other)

The ordering is determined by "first", with "second" breaking ties. Instances with nulls may not be comparable.
