class Gio.IOExtensionPoint¶

Gio.IOExtensionPoint is an opaque data structure and can only be accessed using the following functions.

classmethod implement(extension_point_name, type, extension_name, priority)[source]¶

Parameters:

Returns:

a Gio.IOExtension object for GObject.GType

Return type:

Gio.IOExtension

Registers type as extension for the extension point with name extension_point_name.

If type has already been registered as an extension for this extension point, the existing Gio.IOExtension object is returned.

classmethod lookup(name)[source]¶

Parameters:: name (str) – the name of the extension point
Returns:: the Gio.IOExtensionPoint, or None if there is no registered extension point with the given name.
Return type:: Gio.IOExtensionPoint

Looks up an existing extension point.

classmethod register(name)[source]¶

Parameters:: name (str) – The name of the extension point
Returns:: the new Gio.IOExtensionPoint. This object is owned by GIO and should not be freed.
Return type:: Gio.IOExtensionPoint

Registers an extension point.

get_extension_by_name(name)[source]¶

Parameters:: name (str) – the name of the extension to get
Returns:: the Gio.IOExtension for self that has the given name, or None if there is no extension with that name
Return type:: Gio.IOExtension

Finds a Gio.IOExtension for an extension point by name.

get_extensions()[source]¶

Returns:: a GLib.List of Gio.IOExtensions. The list is owned by GIO and should not be modified.
Return type:: [Gio.IOExtension]

Gets a list of all extensions that implement this extension point. The list is sorted by priority, beginning with the highest priority.

get_required_type()[source]¶

Returns:: the GObject.GType that all implementations must have, or GObject.TYPE_INVALID if the extension point has no required type
Return type:: GObject.GType

Gets the required type for self.

set_required_type(type)[source]¶

Sets the required type for self to type. All implementations must henceforth have this type.
