): Subscription
Subscribes to and pipes this set's state to a mutable subscribable set. Whenever a key added or removed event is received through the subscription, the same key will be added to or removed from the other set.
Parameters
Name | Type | Description |
---|---|---|
to | MutableSubscribableSet <T > | The mutable subscribable set to which to pipe this set's state. |
paused? | boolean | Whether the new subscription should be initialized as paused. Defaults to false . |

▸ pipe<M
>(to
, map
, paused?
): Subscription
Subscribes to this set's state and pipes a mapped version to a mutable subscribable set. Whenever a key added event is received through the subscription, the key will be transformed by the specified mapping function, and the transformed key will be added to the other set. Whenever a key removed event is received, the transformed key is removed from the other set if and only if no remaining key in this set maps to the same transformed key.
