Class ADT.Set (< ValueType >)

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.

Generic ValueType

__generic__ mixed ValueType = mixed

Description

Type for the individual members of the set.

Method create

ADT.Set ADT.Set(void|ADT.Set|array(ValueType)|multiset(ValueType)|mapping(ValueType:mixed) 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.
