Description copied from interface: IOStrategy

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.
