pipe()

Call Signature

pipe(to, paused?): Subscription

Defined in: src/sdk/sub/AbstractSubscribableMap.ts:230

Subscribes to and pipes this subscribable's state to a mutable subscribable. Whenever an update of this subscribable's state is received through the subscription, it will be used as an input to change the other subscribable's state.

Parameters

Parameter	Type	Description
to	MutableSubscribable<any, ReadonlyMap<K, V>>	The mutable subscribable to which to pipe this subscribable's state.
paused?	boolean	Whether the new subscription should be initialized as paused. Defaults to false.

Returns

Subscription

The new subscription.

Implementation of

Subscribable.pipe

Call Signature

pipe<OI, OV>(to, map, paused?): Subscription

Defined in: src/sdk/sub/AbstractSubscribableMap.ts:242

Subscribes to and pipes mapped inputs from another subscribable. Whenever an update of the other subscribable's state is received through the subscription, it will be transformed by the specified mapping function, and the transformed state will be used as an input to change this subscribable's state.

Type Parameters

Type Parameter	Default type	Description
OI	-	The input type of the mutable subscribable to which to pipe.
OV	unknown	The value type of the mutable subscribable to which to pipe.

Parameters

Parameter	Type	Description
to	MutableSubscribable<any, OI>	The mutable subscribable to which to pipe this subscribable's mapped state.
map	(fromVal, toVal) => OI	The function to use to transform inputs.
paused?	boolean	Whether the new subscription should be initialized as paused. Defaults to false.

Returns

Subscription

The new subscription.

Implementation of

Subscribable.pipe

Call Signature

pipe(to, paused?): Subscription

Defined in: src/sdk/sub/AbstractSubscribableMap.ts:251

Subscribes to and pipes this map's state to a mutable subscribable map. Whenever a key-value pair added, changed, or removed event is received through the subscription, the same key-value pair will be added to, changed, or removed from the other map.

Parameters

Parameter	Type	Description
to	MutableSubscribableMap<K, V>	The mutable subscribable map to which to pipe this map's state.
paused?	boolean	Whether the new subscription should be initialized as paused. Defaults to false.

Returns

Subscription

The new subscription.

Implementation of

SubscribableMap.pipe

sub()

sub(handler, initialNotify, paused): Subscription

Defined in: src/sdk/sub/AbstractSubscribableMap.ts:62

Subscribes to changes in this map's state.

Parameters

Parameter	Type	Default value	Description
handler	SubscribableMapHandler<K, V>	undefined	A function which is called when this map's state changes.
initialNotify	boolean	false	Whether to immediately invoke the callback function with this map's current state. Defaults to false. This argument is ignored if the subscription is initialized as paused.
paused	boolean	false	Whether the new subscription should be initialized as paused. Defaults to false.

Returns

Subscription

The new subscription.
