WorkerThreadPoolConfigProducer
All Known Implementing Classes:
AbstractIOStrategy, LeaderFollowerNIOStrategy, SameThreadIOStrategy, SimpleDynamicNIOStrategy, WorkerThreadIOStrategy
public interface IOStrategy extends WorkerThreadPoolConfigProducer
strategy is responsible for making decision how Runnable task will be run: in current thread, worker thread. strategy can make any other processing decisions.

  • Method Details

    • executeIoEvent

      boolean executeIoEvent(Connection connection, IOEvent ioEvent) throws IOException
      The SelectorRunner will invoke this method to allow the strategy implementation to decide how the IOEvent will be handled.
      Parameters:
      connection - the Connection upon which the provided IOEvent occurred.
      ioEvent - the IOEvent that triggered execution of this strategy
      Returns:
      true, if this thread should keep processing IOEvents on the current and other Connections, or false if this thread should hand-off the farther IOEvent processing on any Connections, which means IOStrategy is becoming responsible for continuing IOEvent processing (possibly starting new thread, which will handle IOEvents).
      Throws:
      IOException - if an error occurs processing the IOEvent.

    • executeIoEvent

      boolean executeIoEvent(Connection connection, IOEvent ioEvent, boolean isIoEventEnabled) throws IOException
      The SelectorRunner will invoke this method to allow the strategy implementation to decide how the IOEvent will be handled.
      Parameters:
      connection - the Connection upon which the provided IOEvent occurred.
      ioEvent - the IOEvent that triggered execution of this strategy
      isIoEventEnabled - true if IOEvent is still enabled on the Connection, or false if IOEvent was preliminary disabled or IOEvent is being simulated.
      Returns:
      true, if this thread should keep processing IOEvents on the current and other Connections, or false if this thread should hand-off the farther IOEvent processing on any Connections, which means IOStrategy is becoming responsible for continuing IOEvent processing (possibly starting new thread, which will handle IOEvents).
      Throws:
      IOException - if an error occurs processing the IOEvent.

    • getThreadPoolFor

      Executor getThreadPoolFor(Connection connection, IOEvent ioEvent)
      Returns an Executor to be used to run given ioEvent processing for the given connection. A null value will be returned if the ioEvent should be executed in the kernel thread.
      Parameters:
      connection - Connection
      ioEvent - the event to get the Executor for
      Returns:
      an Executor to be used to run given ioEvent processing for the given connection
