intervals


intervals: order

Essential. Break this up into disjoint intervals

isBoundedAbove

Same meaning as IntegerRegion::isBoundedAbove

isBoundedBelow

Same meaning as IntegerRegion::isBoundedBelow

isEmpty



Overrides: XnRegion

isEnumerable: order

Any representable infinite set of real numbers is also not enumerable

Overrides: XnRegion

isEqual: other



Overrides: XnRegion

isFinite



Overrides: XnRegion

isFull



Overrides: XnRegion

isInterval

Whether this Region is a non-empty interval, ie. if A, B in the Region and A <= C <= B then C is in the Region. This includes inequalities (eg. ) and the fullRegion in addition to ordinary two-ended intervals.

isSimple



Overrides: XnRegion

isSubsetOf: other



Overrides: XnRegion

lowerBound

The largest real number such that all the positions in the region are >= it. Does not necessarily lie in the region. For example, the region of all numbers > 2 has a lowerBound of 2.

stepper: order



Overrides: XnRegion

unionWith: other



Overrides: XnRegion

upperBound

The smallest real number such that all the positions in the region are <= it. Does not necessarily lie in the region. For example, the region of all numbers < 2 has an upperBound of 2.
