In-ports​

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

Out-ports​

output Null — emits an event with a Null value.

Overview​

The Null component stores a Null value that is emitted on the output port immediately after the component is initialized. If the trigger port is connected, then the component will wait for any event on the trigger port before emitting the value. The component will emit its value every time an event is received on the trigger port.

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

Settings​

No settings. The component comes initialized with a Null value.
