BoolSignal

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

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.
