In-ports#

trigger <any> - Any event on this port will trigger the constant to emit its value on output port.

Out-ports#

output Null - Emits event with configured static Null value.

Overview#

Null is a const component that emits event on its output port only once immediately after initialization. If trigger port is connected then the component will wait for any event on trigger port before emitting the constant value. Repeated events on trigger port will trigger repeated constant events.

Null const is often used to inject empty initial values to a stream.
