A lot of the functionality that is accessible through GIO is implemented in loadable modules, and modules provide a convenient way to extend GIO. In addition to the GIOModule API which supports writing such modules, GIO has a mechanism to define extension points, and register implementations thereof, see GIOExtensionPoint. The following extension points are currently defined by GIO: G_VFS_EXTENSION_POINT_NAME.
Allows to override the functionality of the GVfs class.
Implementations of this extension point must be derived from GVfs.
GIO uses the implementation with the highest priority that is active,
see G_VOLUME_MONITOR_EXTENSION_POINT_NAME. Allows to add more volume monitors. Implementations of this extension point must be derived from GVolumeMonitor. GIO uses all registered extensions. gvfs contains an implementation that works together with the GVfs implementation in gvfs. G_NATIVE_VOLUME_MONITOR_EXTENSION_POINT_NAME.
Allows to override the 'native' volume monitor.
Implementations of this extension point must be derived from
GNativeVolumeMonitor. GIO uses the implementation with
the highest priority that is supported, as determined by the
G_LOCAL_FILE_MONITOR_EXTENSION_POINT_NAME.
Allows to override the file monitor implementation for
local files. Implementations of this extension point must
be derived from GLocalFileMonitor. GIO uses the implementation
with the highest priority that is supported, as determined by the
G_LOCAL_DIRECTORY_MONITOR_EXTENSION_POINT_NAME.
Allows to override the directory monitor implementation for
local files. Implementations of this extension point must be
derived from GLocalDirectoryMonitor. GIO uses the implementation
with the highest priority that is supported, as determined by the
G_DESKTOP_APP_INFO_LOOKUP_EXTENSION_POINT_NAME. Unix-only. Allows to provide a way to associate default handlers with URI schemes. Implementations of this extension point must implement the GDesktopAppInfoLookup interface. GIO uses the implementation with the highest priority. gvfs contains a GConf-based implementation that uses the same GConf keys as gnome-vfs. |
