BoolSignal

The BoolSignal class monitors a boolean value.

Properties

Property Description

Property	Description
`lastValue`	(get) lastValue: boolean (set) (Not Available) Specifies a Boolean representing 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.

lastValue

(get) lastValue: boolean
(set) (Not Available)

Specifies a Boolean representing 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
`and`	and(other: BoolSignal): BoolSignal Returns a signal with the value that is the logical conjunction of the values of the given signals. It is `true` every time both input signals are `true` and `false` at all other times. See Also: `ReactiveModule.and`
`delayBy`	delayBy(timeSpan: {milliseconds: number}): this Delays a signal. The argument is an object with a "milliseconds" property specifying the delay duration in milliseconds.
`eq`	eq(other: BoolSignal): 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`
`history`	history(framesCount: number): BoolSignalHistory history(framesCount: number, initialValues: Array<boolean>): BoolSignalHistory Returns an object used to access signal values from past frames. The amount of frames tracked is customizable via `framesCount` parameter. Historical signal values are going to be initialized with signal value at call time or using `initialValues` if provided.
`ifThenElse`	ifThenElse(thenValue: EventSource, elseValue: EventSource): EventSource ifThenElse(thenValue: ScalarSignal, elseValue: ScalarSignal): ScalarSignal ifThenElse(thenValue: StringSignal, elseValue: StringSignal): StringSignal ifThenElse(thenValue: BoolSignal, elseValue: BoolSignal): BoolSignal Returns a signal or an `EventSource` which at any point of time takes the value (passes the events in case of `EventSource`) of one or another inputs, depending on the momentary value of the given `BoolSignal`.
`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: BoolSignal): 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`
`not`	not(): BoolSignal Returns a signal with the logically negated value of the given signal. See Also: `ReactiveModule.not`
`onOff`	onOff(): EventSource onOff(config: { fireOnInitialValue: ?boolean}): EventSource Returns an `EventSource` that emits an event every time the value of the input signal changes to `false`. 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 it's `false` straight away. If `config.fireOnInitialValue` is set to `true` then an event for initial signal value is also emitted. `oldValue` is unset for this initial event.
`onOn`	onOn(): EventSource onOn(config: { fireOnInitialValue: ?boolean}): EventSource Returns an `EventSource` that emits an event every time the value of the input signal changes to `true`. 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 it's `true` straight away. If `config.fireOnInitialValue` is set to `true` then an event for initial signal value is also emitted. `oldValue` is unset for this initial event.
`or`	or(other: BoolSignal): BoolSignal Returns a signal with the value that is the logical disjunction of the values of the given signals. It is `true` every time at least one of the input signals is `true` and `false` at all other times. See Also: `ReactiveModule.or`
`pin`	pin(): BoolSignal Returns a `BoolSignal` containing a constant value which is the value of the specified signal immediately after `pin` is called.
`pinLastValue`	pinLastValue(): ConstBoolSignal Returns a `ConstBoolSignal` containing a constant value which is the last value of the specified signal before `pinLastValue` is called. ConstBoolSignal can be passed to a functions which accept bool.
`xor`	xor(other: BoolSignal): BoolSignal Returns a signal with the value that is the logical exclusive disjunction of the values of the given signals. It is `true` every time exactly one of the input signals is `true` and `false` at all other times. Note: It is equivalent to `BoolSignal.ne`. See Also: `ReactiveModule.xor`
