Pike v8.1 release 6

Class ADT.Set

Description

ADT.Set implements a datatype for sets. These sets behave much like multisets, except that they are restricted to containing only one instance of each member value.

From a performance viewpoint, it is probably more efficient for a Pike program to use mappings to serve as sets, rather than using an ADT.Set,so ADT.Set is mainly provided for the sake of completeness and code readability.


Method create

ADT.Set ADT.Set(void|ADT.Set|array|multiset|mapping initial_data)

Description

Create an ADT.Set, optionally initialized from another ADT.Set or a compatible type. If no initial data is given, the set will start out empty.
