public class ChannelReceive<T> extends ChannelStep<java.lang.Void,T>
|Constructor and Description|
Creates a new instance that receives from a channel the ID of which is provided in a state relation.

This method must be implemented by subclasses to provide the actual functionality of this step.
Suspends until a value can be received from a certain channel.
Suspends until a value can be received from the channel with the ID provided by the given function.

Subclasses that need to suspend the invocation of the next step until
some condition is met (e.g. sending or receiving data has finished) need
to override this method and create a
Suspension by invoking
Continuation.suspend(CoroutineStep, CoroutineStep) on the next
step. If the condition that caused the suspension resolves the coroutine
execution can be resumed by calling
Subclasses that override this method also need to handle errors by
terminating any further execution (i.e. not resuming a suspension if such
exists) and forwarding the causing exception to
