Method Detail

complement

public XnRegion complement()

Description copied from class: XnRegion

Essential. Return a region of containing exactly those positions not in this region. The complement of a distinction must be a distinction.

Specified by:

complement in class Filter

intersect

public XnRegion intersect(XnRegion other)

Description copied from class: XnRegion

Essential. The intersection of two simple regions must be simple. The intersection of two distinctions must therefore be a simple region. The result has exactly those members which both the original regions have.

Overrides:

intersect in class Filter

minus

public XnRegion minus(XnRegion other)

Description copied from class: XnRegion

The region containing all my position which aren't in other.

Overrides:

minus in class XnRegion

unionWith

public XnRegion unionWith(XnRegion other)

Description copied from class: XnRegion

The result has as members exactly those positions which are members of either of the original two regions. No matter how simple the two original regions are, the result may be non-simple. The only reason this is called 'unionWith' instead of 'union' is that the latter is a C++ keyword.

Overrides:

unionWith in class Filter

match

public boolean match(XnRegion region)

tell whether a region passes this filter

Specified by:

match in class Filter

pass

public Filter pass(Joint parent)

return the simplest filter for looking at the children

Specified by:

pass in class Filter

actualHashForEqual

public int actualHashForEqual()

Description copied from class: Heaper

Defined by subclasses to produce the value returned by hashForEqual.

Overrides:

actualHashForEqual in class Filter

isAllFilter

public boolean isAllFilter()

Description copied from class: Filter

Essential. Whether this is an 'all' Filter, i.e. it only matches Regions which contain everything in the baseRegion

Specified by:

isAllFilter in class Filter

isAnyFilter

public boolean isAnyFilter()

Description copied from class: Filter

Essential. Whether this is an 'any' Filter, i.e. it matches Regions which contain anything in the baseRegion

Specified by:

isAnyFilter in class Filter

isEmpty

public boolean isEmpty()

Description copied from class: XnRegion

Every coordinate space has exactly one empty region. It is the one containing no positions. It and only it responds 'true' to this message.

Specified by:

isEmpty in class Filter

isEqual

public boolean isEqual(Heaper other)

Description copied from class: XnRegion

Two regions are equal iff they contain exactly the same set of positions

Specified by:

isEqual in class Filter

isFull

public boolean isFull()

Description copied from class: XnRegion

true if this is the largest possible region in this space -- the region that contains all positions in the space. Note that in a space which has no positions (which is perfectly valid), the one XuRegion would be both empty (since it has no positions) and full (since it has all the positions in the space).

Specified by:

isFull in class Filter

printOn

public void printOn(java.io.PrintWriter oo)

Description copied from class: Heaper

This should rarely be overridden. In Tofu, it prints ClassName(...), where ... is either produced by printInsideOn or is ??? if printInsideOn it not overridden.

Overrides:

printOn in class Heaper

fetchSpecialSubset

public XnRegion fetchSpecialSubset(XnRegion other)

Description copied from class: Filter

return self or other if one is clearly a subset of the other, else NULL

Specified by:

fetchSpecialSubset in class Filter

intersectedFilters

public Stepper intersectedFilters()

Description copied from class: Filter

Essential. Break this up into a bunch of Filters which when intersected (anded) together give this one. If there is only one sub Filter it will be the receiver; otherwise, the sub Filters will be simple enough that either they or their complements will return true from at least one of isAndFilter or isOrFilter. If this is full (i.e. an open filter) then the stepper will have no elements.

Specified by:

intersectedFilters in class Filter

unionedFilters

public Stepper unionedFilters()

Description copied from class: Filter

Essential. Break this up into a bunch of Filters which when unioned (ored) together give this one. If there is only one sub Filter it will be the receiver; otherwise, the sub Filters will be simple enough that either they or their complements will return true from at least one of isAndFilter or isOrFilter. The sub Filters might not be disjoint Regions. If this is empty (i.e. a closed filter) then the stepper will have no elements.

Specified by:

unionedFilters in class Filter

baseRegion

public XnRegion baseRegion()

Description copied from class: Filter

Essential. A region in the base space identifying what kind of filter this is. Succeeds only if this isAnyFilter or isAllFilter.

Specified by:

baseRegion in class Filter

relevantRegion

public XnRegion relevantRegion()

Description copied from class: Filter

The region which is relevant to this filter, i.e. whose presence or absence in a region can change whether it passes the filter

Specified by:

relevantRegion in class Filter

sendSelfTo

public void sendSelfTo(Xmtr xmtr)

Overrides:

sendSelfTo in class Filter

make

public static Filter make(CoordinateSpace space)
