Properties

ReadonlyaddChangeListener

addChangeListener: (listener: ChangeListener) => ChangeListenerRemover

Adds a listener that will be called when this binding changes.

Type declaration

See

useBindingEffect and BindingsConsumer

Readonlyget

get: () => GetType

Type declaration

ReadonlygetChangeUid

getChangeUid: () => string

Every time the value is changed, the change uid is updated

Readonlyid

id: string

A technical, but human-readable ID, which isn't guaranteed to be unique

ReadonlyisBinding

isBinding: true

A marker indicating that this is a binding type

ReadonlyisLocked

isLocked: () => boolean

Type declaration

    • (): boolean

    • Returns boolean

      true if the binding is locked

ReadonlyisModified

isModified: () => boolean

Type declaration

    • (): boolean

    • Returns boolean

      true if this binding has been marked as being modified

Readonlylock

lock: () => () => void

Increments the lock count and returns a method to decrement it. A binding is locked if its lock count is > 0. When a binding is locked, mutating calls (reset/set/setRaw) won't have an immediate effect. However, if a mutating call is made on a locked binding, the change will be applied once the binding becomes unlocked.

Type declaration

    • (): () => void

    • Returns () => void

      a function for decrementing this binding's lock count.

ReadonlytriggerChangeListeners

triggerChangeListeners: () => void

Forcibly triggers the change listeners. Don't normally use this!

Readonlyuid

uid: string

An ID that's unique to this runtime
