In-ports​

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

Out-ports​

output Null — emits an event with a Null value.

Overview​

The Null component emits Null on the output port immediately after initialization. When the trigger port is connected, the component waits for an event on this port before emitting anything. Subsequently, it emits Null each time the trigger port receives an event.

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

Settings​

This component has no configurable settings, as it is pre-initialized with a Null value.
