StringSignalSource

Represents a source used to get and set the value of a StringSignal.
Typically, changing the value that a signal contains requires a total reassignment:

TouchGestures.onTap().subscribe((gesture) => {
someSignal = Reactive.val("Hello");
});


In the example above, someSignal is bound to a completely new signal which itself contains the desired value.

The StringSignalSource API provides the ability to change the value of the original signal without reassignment, with behavior similar to that of non-reactive programming models.

Example

Properties

PropertyDescription
signal
(get) signal: StringSignal
(set) (Not Available)


The signal being monitored by the StringSignalSource object.
Accessing the signal's value before one has been assigned via set() will return an empty string.

Methods

MethodDescription
dispose
dispose(): void


Disposes of the native resources associated with the StringSignalSource object.
The StringSignalSource object will still exist as a JavaScript object but will not receive updates through future calls to set(). Do not call dispose() until you're certain that the signal is no longer required.

When calling ReactiveModule.stringSignalSource, avoid reusing the sourceId of an object that you've called dispose() on.
set
set(value: StringSignal | string): void


Sets the value of the signal monitored by the StringSignalSource object to value.
The updated signal value will be propagated throughout all signals related to the StringSignalSource.

If set() is called before signal, signal will return the value assigned by set() when called, rather than the default empty string.

* value - the value to assign to the signal, as a string or StringSignal.
