Interface ComparableTuple<CONCRETE_TUPLE extends ComparableTuple<CONCRETE_TUPLE>>

Type Parameters:

CONCRETE_TUPLE - the concrete ComparableTuple sub-type

All Superinterfaces:

Comparable<CONCRETE_TUPLE>, Serializable

All Known Implementing Classes:

ComparableEmpty, ComparablePair, ComparableSingle, ComparableTriple

public interface ComparableTuple<CONCRETE_TUPLE extends ComparableTuple<CONCRETE_TUPLE>>
extends Comparable<CONCRETE_TUPLE>, Serializable

Base interface for all ComparableTuple's.
A ComparableTuple is an immutable object that can contain the following (supported) number of elements:

Number of element in Tuple	Concrete ComparableTuple type	Factory method
0	ComparableEmpty	empty()
1	ComparableSingle	of(Comparable)
2	ComparablePair	of(Comparable, Comparable)
3	ComparableTriple	of(Comparable, Comparable, Comparable)

Note: ComparableTuple (and its subclasses) supports Object.equals(Object) comparison using subclasses for the different subclasses
