pipe()

Call Signature

pipe(to, paused?): Subscription

Defined in: src/sdk/sub/AbstractSubscribableSet.ts:224

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, ReadonlySet<T>>	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

Subscribable.pipe

Call Signature

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

Defined in: src/sdk/sub/AbstractSubscribableSet.ts:236

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/AbstractSubscribableSet.ts:244

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

Parameter	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.

Returns

Subscription

The new subscription.

Implementation of

SubscribableSet.pipe

Call Signature

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

Defined in: src/sdk/sub/AbstractSubscribableSet.ts:257

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.

Type Parameters

Type Parameter	Description
OT	The element type of the set to which to pipe.

Parameters

Parameter	Type	Description
to	MutableSubscribableSet<OT>	The mutable subscribable to which to pipe this set's mapped state.
map	(fromKey) => OT	The function to use to transform keys.
paused?	boolean	Whether the new subscription should be initialized as paused. Defaults to false.

Returns

Subscription

The new subscription.

sub()

sub(handler, initialNotify, paused): Subscription

Defined in: src/sdk/sub/AbstractSubscribableSet.ts:57

Subscribes to changes in this set's state.

Parameters

Parameter	Type	Default value	Description
handler	SubscribableSetHandler<T>	undefined	A function which is called when this set's state changes.
initialNotify	boolean	false	Whether to immediately invoke the callback function with this set'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.
