class Gtk::Bitset

• Gtk::Bitset
• Reference
• Object

Overview

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.

Defined in:
