trait AkkaStreamletContext extends StreamletContext
Runtime context for AkkaStreamlets, which provides means to create Sources and Sinks respectively
for CodeInlets and CodeOutlets.
The StreamletContext also contains some lifecycle hooks, like signalReady
, onStop
and stop
and provides access to the streamlet configuration.
It also provides the ActorSystem and Materializer that will be used to run the AkkaStreamlet.

signalReady(): Boolean
Signals that the streamlet is ready to process data.
Signals that the streamlet is ready to process data.
When a streamlet is run using
AkkaStreamletTestkit.run
, a StreamletExecution is returned.signalReady
completes the ready future. ready can be used for instance to wait for a Server to signal that it is ready to accept requests.- returns
true
if and only if successfully signalled. Otherwisefalse
