Direct Known Subclasses:

GenericCrossDsp

public abstract class CrossMapping

extends Dsp

All other crossed mappings must be gotten by factoring the non-dsp aspects out into the generic non-dsp mapping objects. This class represents what remains after the factoring.

Constructor Summary

protected	CrossMapping()
protected	CrossMapping(Rcvr rcvr)

Method Summary

abstract Dsp	compose(Dsp other) Return the composition of the two Dsps.
abstract CoordinateSpace	coordinateSpace() the coordinate space of the domain and range of the Dsp
static void	info() {Dsp CLIENT} subMapping: index {Int32} {PtrArray CLIENT of: Dsp} subMappings
abstract Mapping	inverse() Return the inverse of this transformation.
abstract boolean	isIdentity() Says whether this Dsp maps every Position onto itself
static CrossMapping	make(CrossSpace space)
static CrossMapping	make(CrossSpace space, PtrArray subDsps)
abstract Dsp	minus(Dsp other) Return the difference of the two Dsps.
abstract XnRegion	ofAll(XnRegion reg) If 'reg' is a simple region, then the result must also be simple
abstract Dsp	subMapping(int index) The Dsp applied to Positions in the given subspace.
abstract PtrArray	subMappings() The Mappings applied to Positions in each of the subspaces.

Constructor Detail

CrossMapping

protected CrossMapping()

CrossMapping

protected CrossMapping(Rcvr rcvr)

Method Detail

ofAll

public abstract XnRegion ofAll(XnRegion reg)

Description copied from class: Dsp

If 'reg' is a simple region, then the result must also be simple

Specified by:

ofAll in class Dsp

compose

public abstract Dsp compose(Dsp other)

Description copied from class: Dsp

Return the composition of the two Dsps. Two Dsps of the same space are always composable. (a->compose(b) ->minus(b))->isEqual (a) (a->compose(b) ->of(pos))->isEqual (a->of (b->of (pos))

Specified by:

compose in class Dsp

inverse

public abstract Mapping inverse()

Description copied from class: Dsp

Return the inverse of this transformation. Considering the Dsp as a set of pairs (see class comment), return the Dsp which has the mirror image of all my pairs.

Specified by:

inverse in class Dsp

minus

public abstract Dsp minus(Dsp other)

Description copied from class: Dsp

Return the difference of the two Dsps. (a->compose(b) ->minus(b))->isEqual (a)

Specified by:

minus in class Dsp

coordinateSpace

public abstract CoordinateSpace coordinateSpace()

Description copied from class: Dsp

the coordinate space of the domain and range of the Dsp

Specified by:

coordinateSpace in class Dsp

isIdentity

public abstract boolean isIdentity()

Description copied from class: Dsp

Says whether this Dsp maps every Position onto itself

Specified by:

isIdentity in class Dsp

subMapping

public abstract Dsp subMapping(int index)

The Dsp applied to Positions in the given subspace.

subMappings

public abstract PtrArray subMappings()

The Mappings applied to Positions in each of the subspaces. Each of these is already simple enough that it is either the identityMapping or a visible subclass like IntegerMapping.

make

public static CrossMapping make(CrossSpace space,
                                PtrArray subDsps)

make

public static CrossMapping make(CrossSpace space)

info

public static void info()

{Dsp CLIENT} subMapping: index {Int32} {PtrArray CLIENT of: Dsp} subMappings
