Properties: Set Properties Class

In set6: R6 Mathematical Sets Interface

Description

Used to store the properties of a Set. Though this is not an abstract class, it should never be constructed outside of the Set constructor.

Active bindings

closure

Returns the closure of the Set. One of "open", "half-open", or "closed."

countability

Returns the countability of the Set. One of "countably finite", "countably infinite", or "uncountable".

cardinality

Returns the cardinality of the Set. Either an integer if the Set is countably finite, Aleph0 if countably infinite, or a Beth number.

empty

Returns if the Set is empty or not. TRUE if the Set cardinality is 0, FALSE otherwise.

singleton

Returns if the Set is a singleton or not. TRUE if the Set cardinality is 1, FALSE otherwise.
