Direct Known Subclasses:

HeaperAsPosition

public abstract class UnOrdered

extends Position

A convenient superclass of all Positions which have no natural ordering. See UnOrdered::isGE for the defining property of this class. This class should probably go away and UnOrdered::isGE distributed to the subclasses.

Constructor Summary

protected	UnOrdered()
protected	UnOrdered(Rcvr rcvr)

Method Summary

int	actualHashForEqual() since we redefine equal, subclasses had better redefine actualHashForEqual
abstract XnRegion	asRegion() Essential.
abstract CoordinateSpace	coordinateSpace() Essential.
abstract boolean	isEqual(Heaper other) Up in position, isGE is deferred, and isEqual is defined in terms of isEqual.

Method Detail

asRegion

public abstract XnRegion asRegion()

Description copied from class: Position

Essential. A region containing this position as its only element.

Specified by:

asRegion in class Position

coordinateSpace

public abstract CoordinateSpace coordinateSpace()

Description copied from class: Position

Essential. The coordinate space this is a position in. This implies that a position object is only a position in one particular coordinate space.

Specified by:

coordinateSpace in class Position

actualHashForEqual

public int actualHashForEqual()

Description copied from class: Position

since we redefine equal, subclasses had better redefine actualHashForEqual

Overrides:

actualHashForEqual in class Position

isEqual

public abstract boolean isEqual(Heaper other)

Up in position, isGE is deferred, and isEqual is defined in terms of isEqual. Here in UnOrdered, we define isGE in terms of isEqual, so we must redefine isEqual to be deferred.

Specified by:

isEqual in class Position
