HookList

class HookList(*args, **kwargs)

The HookList struct represents a list of hook functions.

Methods

class HookList

clear() → None

Removes all the Hook elements from a HookList.

init(hook_size: int) → None

Initializes a HookList. This must be called before the HookList is used.

Parameters:

hook_size – the size of each element in the HookList, typically sizeof (GHook).

invoke(may_recurse: bool) → None

Calls all of the Hook functions in a HookList.

Parameters:

may_recurse – True if functions which are already running (e.g. in another thread) can be called. If set to False, these are skipped

invoke_check(may_recurse: bool) → None

Calls all of the Hook functions in a HookList. Any function which returns False is removed from the HookList.

Parameters:

may_recurse – True if functions which are already running (e.g. in another thread) can be called. If set to False, these are skipped

marshal(may_recurse: bool, marshaller: Callable[[Hook, Any], None], marshal_data: Any = None) → None

Calls a function on each valid Hook.

Parameters:

• may_recurse – True if hooks which are currently running (e.g. in another thread) are considered valid. If set to False, these are skipped

• marshaller – the function to call for each Hook

• marshal_data – data to pass to marshaller

marshal_check(may_recurse: bool, marshaller: Callable[[Hook, Any], bool], marshal_data: Any = None) → None

Calls a function on each valid Hook and destroys it if the function returns False.

Parameters:

• may_recurse – True if hooks which are currently running (e.g. in another thread) are considered valid. If set to False, these are skipped

• marshaller – the function to call for each Hook

• marshal_data – data to pass to marshaller

Fields

class HookList

dummy

Unused

dummy3

Unused

finalize_hook

The function to call to finalize a Hook element.

The default behaviour is to call the hooks destroy function

hook_size

The size of the HookList elements, in bytes

hooks

The first Hook element in the list

is_setup

1 if the HookList has been initialized

seq_id

The next free Hook id
