  groovyx.gpars.serial.WithSerialId
      groovyx.gpars.actor.impl.MessageStream
          groovyx.gpars.dataflow.DataCallbackWithPool

public final class DataCallbackWithPool
extends MessageStream

A helper class enabling the 'whenBound()' or 'getValAsync' functionality of a DataflowVariable and DataflowQueue, whenever a thread pool instead of a PGroup is specified.. A task that waits asynchronously on the DFV to be bound. Once the DFV is bound, upon receiving the message the actor runs the supplied closure / code with the DFV value as a parameter.
