Methods

get

get(): T

Gets this item's state.

Returns

T

This item's state.

map

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

Maps this subscribable to a new subscribable.

Type parameters

Name
M

Parameters

NameTypeDescription
fn(input: T, previousVal?: M) => MThe function to use to map to the new subscribable.
equalityFunc?(a: M, b: M) => booleanThe function to use to check for equality between mapped values. Defaults to the strict equality comparison (===).

Returns

MappedSubscribable<M>

The mapped subscribable.

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

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

Type parameters

Name
M

Parameters

NameTypeDescription
fn(input: T, previousVal?: M) => MThe function to use to map to the new subscribable.
equalityFunc(a: M, b: M) => booleanThe function to use to check for equality between mapped values.
mutateFunc(oldVal: M, newVal: M) => voidThe function to use to change the value of the mapped subscribable.
initialValMThe initial value of the mapped subscribable.

Returns

MappedSubscribable<M>

The mapped subscribable.

pipe

pipe(to, paused?): Subscription

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

NameTypeDescription
toMutableSubscribable<any, T>The mutable subscribable to which to pipe this subscribable's state.
paused?booleanWhether the new subscription should be initialized as paused. Defaults to false.

Returns

Subscription

The new subscription.

Inherited from

Subscribable.pipe

Defined in

src/sdk/sub/Subscribable.ts:60

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

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

Name
M

Parameters

NameTypeDescription
toMutableSubscribable<any, M>The mutable subscribable to which to pipe this subscribable's mapped state.
map(fromVal: T, toVal: M) => MThe function to use to transform inputs.
paused?booleanWhether the new subscription should be initialized as paused. Defaults to false.

Returns

Subscription

The new subscription.

Subscribable.pipe

set

set(value): void

Sets the state of this item.

Parameters

NameTypeDescription
valueIThe input used to change the state.

Returns

void

Inherited from

MutableAccessible.set

Defined in

src/sdk/sub/Accessible.ts:21


sub

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

Subscribes to changes in this subscribable's state.

Parameters

NameTypeDescription
handler(value: T) => voidA function which is called when this subscribable's state changes.
initialNotify?booleanWhether 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?booleanWhether the new subscription should be initialized as paused. Defaults to false.

Returns

Subscription

The new subscription.

Inherited from

Subscribable.sub

Defined in

src/sdk/sub/Subscribable.ts:19


unsub

unsub(handler): void

Unsubscribes a callback function from this subscribable.

Parameters

NameTypeDescription
handler(value: T) => voidThe function to unsubscribe.

Returns

void

Deprecated

This method has been deprecated in favor of using the Subscription object returned by .sub() to manage subscriptions.
