class Gtk::Bitset
- Gtk::Bitset
- Reference
- Object
Overview
A Gtk::Bitset represents a set of unsigned integers.
Another name for this data structure is "bitmap".
The current implementation is based on roaring bitmaps.
A bitset allows adding a set of integers and provides support for set operations
like unions, intersections and checks for equality or if a value is contained
in the set. Gtk::Bitset also contains various functions to query metadata about
the bitset, such as the minimum or maximum values or its size.
The fastest way to iterate values in a bitset is Gtk::BitsetIter.
The main use case for Gtk::Bitset is implementing complex selections for
Gtk::SelectionModel.
