Details

class GLib.Hook

The GLib.Hook struct represents a single hook function in a GLib.HookList.

classmethod destroy_link(hook_list, hook)

Parameters:

• hook_list (GLib.HookList) – a GLib.HookList
• hook (GLib.Hook) – the GLib.Hook to remove

Removes one GLib.Hook from a GLib.HookList, marking it inactive and calling GLib.Hook.unref() on it.

classmethod free(hook_list, hook)

Parameters:

• hook_list (GLib.HookList) – a GLib.HookList
• hook (GLib.Hook) – the GLib.Hook to free

Calls the GLib.HookList finalize_hook function if it exists, and frees the memory allocated for the GLib.Hook.

classmethod insert_before(hook_list, sibling, hook)

Parameters:

• hook_list (GLib.HookList) – a GLib.HookList
• sibling (GLib.Hook or None) – the GLib.Hook to insert the new GLib.Hook before
• hook (GLib.Hook) – the GLib.Hook to insert

Inserts a GLib.Hook into a GLib.HookList, before a given GLib.Hook.

classmethod prepend(hook_list, hook)

Parameters:

• hook_list (GLib.HookList) – a GLib.HookList
• hook (GLib.Hook) – the GLib.Hook to add to the start of hook_list

Prepends a GLib.Hook on the start of a GLib.HookList.

classmethod unref(hook_list, hook)

Parameters:

• hook_list (GLib.HookList) – a GLib.HookList
• hook (GLib.Hook) – the GLib.Hook to unref

Decrements the reference count of a GLib.Hook. If the reference count falls to 0, the GLib.Hook is removed from the GLib.HookList and GLib.Hook.free() is called to free it.

compare_ids(sibling)

Parameters:sibling (GLib.Hook) – a GLib.Hook to compare with self Returns:a value <= 0 if the id of sibling is >= the id of self Return type:int

Compares the ids of two GLib.Hook elements, returning a negative value if the second id is greater than the first.
