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.
