Interface: MutableSubscribable<T, I>

Defined in: src/sdk/sub/Subscribable.ts:113

A subscribable that can accept inputs to change its state. The state of the subscribable may be derived from the inputs directly or from transformed versions of the inputs.

Methods

get()

get(): T

Defined in: src/sdk/sub/Accessible.ts:9

map()

Call Signature

map<M>(fn, equalityFunc?): MappedSubscribable<M>

Defined in: src/sdk/sub/Subscribable.ts:28

Maps this subscribable to a new subscribable.

Type Parameters

Type Parameter
M

Parameters

Parameter	Type	Description
fn	(input, previousVal?) => M	The function to use to map to the new subscribable.
equalityFunc?	(a, b) => boolean	The function to use to check for equality between mapped values. Defaults to the strict equality comparison (===).

Returns

MappedSubscribable<M>

The mapped subscribable.

Inherited from

Subscribable.map

Call Signature

map<M>(fn, equalityFunc, mutateFunc, initialVal): MappedSubscribable<M>

Defined in: src/sdk/sub/Subscribable.ts:37

Maps this subscribable to a new subscribable with a persistent, cached value which is mutated when it changes.

Type Parameters

Type Parameter
M

Parameters

Parameter	Type	Description
fn	(input, previousVal?) => M	The function to use to map to the new subscribable.
equalityFunc	(a, b) => boolean	The function to use to check for equality between mapped values.
mutateFunc	(oldVal, newVal) => void	The function to use to change the value of the mapped subscribable.
initialVal	M	The initial value of the mapped subscribable.

Returns

MappedSubscribable<M>

The mapped subscribable.

pipe()

Call Signature

pipe(to, paused?): Subscription

Defined in: src/sdk/sub/Subscribable.ts:52

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, 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

The new subscription.

Inherited from

Subscribable.pipe

Call Signature

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

Defined in: src/sdk/sub/Subscribable.ts:64

Subscribes to this subscribable's state and pipes a mapped version to a mutable subscribable. Whenever an update of this 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 the other 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<OV, 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.

set()

set(value): void

Defined in: src/sdk/sub/Accessible.ts:21

Sets the state of this item.

Parameters

Parameter	Type	Description
value	I	The input used to change the state.

Returns

void

MutableAccessible.set

sub()

sub(handler, initialNotify?, paused?): Subscription

Defined in: src/sdk/sub/Subscribable.ts:19

Subscribes to changes in this subscribable's state.

Parameters

Parameter	Type	Description
handler	(value) => void	A function which is called when this subscribable's state changes.
initialNotify?	boolean	Whether to immediately invoke the callback function with this subscribable's current state. Defaults to false. This argument is ignored if the subscription is initialized as paused.
paused?	boolean	Whether the new subscription should be initialized as paused. Defaults to false.

Returns

Subscription

The new subscription.
