Class FilterSpace

A FilterSpace can be described mathematically as a power space of its baseSpace, ie. the set of all subsets of the baseSpace. Each position in a FilterSpace is a Region in the baseSpace, and each Filter is a set of Regions taken from the baseSpace. See Filter for more detail.

Overrides: CoordinateSpace

notSubsetFilter: region

A filter matching any regions that is not a subset of the given region.

notSupersetFilter: region

A filter that matches any region that is not a superset of the given region.

orFilter: subs

A filter that matches any region that any of the filters in the set would have matched.

position: baseRegion

Essential. Given a Region in the baseSpace, make a Position which corresponds to it, so that
filter->hasMember (this->position (baseRegion)) iff filter->match (baseRegion)
