launch.actions.register_event_handler module

Module for the RegisterEventHandler action.

class launch.actions.register_event_handler.RegisterEventHandler

Bases: Action

Action that registers an event handler.

Event handlers that are registered in this action will not be matched to an event that is in the process of being handled. For example, if you have an event handler for event ‘Foo’, which returns an instance of RegisterEventHandler for a new event handler that handles the event ‘Foo’ as well, that event handler will not be matched with the instance of the ‘Foo’ event that caused it to be registered in the first place.

__init__(event_handler: BaseEventHandler, **kwargs) → None

describe_conditional_sub_entities() → List[Tuple[str, Iterable[LaunchDescriptionEntity]]]

property event_handler: BaseEventHandler

Getter for self.__event_handler.

execute(context: LaunchContext)

Execute the action.
