class HookList(*args, **kwargs)

Constructors:

HookList()

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[[...], None], *marshal_data: Any) → 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[[...], bool], *marshal_data: Any) → 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
