class: Bitset

[20:7] extends: object

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. GtkBitset 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 [struct@Gtk.BitsetIter]. The main use case for GtkBitset is implementing complex selections for [iface@Gtk.SelectionModel].

Methods

• Bitset (Handle = null)

  Creates a new Bitset by wrapping a native handle or another wrapper.

  • @p Handle is the native handle or another wrapper whose handle to adopt.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.
