executionContext: ExecutionContextExecutor
Running a flow graph will require execution resources, as will computations within Sources, Sinks, etc.
Running a flow graph will require execution resources, as will computations within Sources, Sinks, etc. This scala.concurrent.ExecutionContextExecutor can be used by parts of the flow to submit processing jobs for execution, run Future callbacks, etc.
Note that this is not necessarily the same execution context the stream operator itself is running on.

materialize[Mat](runnable: Graph[ClosedShape, Mat], defaultAttributes: Attributes): Mat
This method interprets the given Flow description and creates the running stream using an explicitly provided Attributes as top level (least specific) attributes that will be defaults for the materialized stream.
This method interprets the given Flow description and creates the running stream using an explicitly provided Attributes as top level (least specific) attributes that will be defaults for the materialized stream. The result can be highly implementation specific, ranging from local actor chains to remote-deployed processing networks.

scheduleOnce(delay: FiniteDuration, task: Runnable): Cancellable
Interface for operators that need timer services for their functionality.
Interface for operators that need timer services for their functionality. Schedules a single task with the given delay.
- returns
A akka.actor.Cancellable that allows cancelling the timer. Cancelling is best effort, if the event has been already enqueued it will not have an effect.

schedulePeriodically(initialDelay: FiniteDuration, interval: FiniteDuration, task: Runnable): Cancellable
Interface for operators that need timer services for their functionality.
Interface for operators that need timer services for their functionality. Schedules a repeated task with the given interval between invocations.
- returns
A akka.actor.Cancellable that allows cancelling the timer. Cancelling is best effort, if the event has been already enqueued it will not have an effect.

shutdown(): Unit
Shuts down this materializer and all the operators that have been materialized through this materializer.
Shuts down this materializer and all the operators that have been materialized through this materializer. After having shut down, this materializer cannot be used again. Any attempt to materialize operators after having shut down will result in an IllegalStateException being thrown at materialization time.
