Property Description

Property	Description
`lastValue`	`(get) lastValue: string (set) (Not Available)` Specifies a string that represents the last value of the signal. Note: The signal value is updated during simulation tick. This means that the value of `lastValue` is undefined before its first update. It is also undefined for signals that aren't used for any bindings/subscriptions, because those signals aren't guaranteed to be updated at each simulation tick.

Specifies a string that represents the last value of the signal.

Note: The signal value is updated during simulation tick. This means that the value of lastValue is undefined before its first update. It is also undefined for signals that aren't used for any bindings/subscriptions, because those signals aren't guaranteed to be updated at each simulation tick.

Methods

Method	Description
`concat`	`concat(other: StringSignal): StringSignal` Returns a `StringSignal` containing the concatenation of the values specified by the input signals. See Also: `ReactiveModule.concat`
`delayBy`	`delayBy({milliseconds: number}): StringSignal` Delays a string signal. The argument is an object with a "milliseconds" property specifying the delay duration in milliseconds.
`eq`	`eq(other: StringSignal): BoolSignal` Returns a Boolean signal that takes the value of `true` every time when the value of the left-hand-side signal is equal to the value of the right-hand-side one, and the value of `false` all other time. See Also: `ReactiveModule.eq`
`monitor`	`monitor(): EventSource monitor(config: { fireOnInitialValue: ?boolean}): EventSource` Returns an `EventSource` that emits an event every time the value of the input signal changes. The event contains a JSON object with the old and new values in the format: `{ "oldValue": val, "newValue": val }` Note: By default, there is no event fired for the initial value of the signal. If `config.fireOnInitialValue` is set to `true` then an event for initial signal value is also emitted. `oldValue` is unset for this initial event.
`ne`	`ne(other: StringSignal): BoolSignal` Returns a Boolean signal that takes the value of `true` every time when the value of the left-hand-side signal is not equal to the value of the right-hand-side one, and the value of `false` all other time. See Also: `ReactiveModule.ne`
`pin`	`pin(): StringSignal` Returns a `StringSignal` containing a constant value which is the value of the specified signal immediately after `pin` is called.
