Provided Methods

fn add_action(&self, action: &impl IsA<Action>)

Adds an action to the @self.

If the action map already contains an action with the same name as @action then the old action is dropped from the action map.

The action map takes its own reference on @action.

action

a Action

fn lookup_action(&self, action_name: &str) -> Option<Action>

Looks up the action with the name @action_name in @self.

If no such action exists, returns NULL.

action_name

the name of an action

Returns

a Action

fn remove_action(&self, action_name: &str)

Removes the named action from the action map.

If no action of this name is in the map then nothing happens.

action_name

the name of the action
