Class DirectReactor
java.lang.Object
org.simpleframework.transport.reactor.DirectReactor
- All Implemented Interfaces:
Reactor
The
DirectReactor
object is used to execute the ready
operations of within a single synchronous thread. This is used
when the I/O operations to be performed do not require much time
to execute and so will not block the execution thread.- Author:

This method is used to execute the provided operation without the need to specifically check for I/O events.void
This method is used to execute the provided operation when there is an I/O event that task is interested in.void
stop()
This is used to stop the reactor so that further requests to execute operations does nothing.

DirectReactor
Constructor for theDirectReactor
object. This is used to create a reactor that does not require thread pooling to execute the ready operations. All I/O operations are run in the selection thread and should complete quickly.- Throws:
IOException

process
This method is used to execute the provided operation without the need to specifically check for I/O events. This is used if the operation knows that theSelectableChannel
is ready, or if the I/O operation can be performed without knowing if the channel is ready. Typically this is an efficient means to perform a poll rather than a select on the channel.- Specified by:
process
in interfaceReactor
- Parameters:
task
- this is the task to execute immediately- Throws:
IOException
-
process
This method is used to execute the provided operation when there is an I/O event that task is interested in. This will used the operationsSelectableChannel
object to determine the events that are ready on the channel. If this reactor is interested in any of the ready events then the task is executed.- Specified by:
process
in interfaceReactor
- Parameters:
task
- this is the task to execute on interested eventsrequire
- this is the bit-mask value for interested events- Throws:
IOException
-
stop
This is used to stop the reactor so that further requests to execute operations does nothing. This will clean up all of the reactors resources and unregister any operations that are currently awaiting execution. This should be used to ensure any threads used by the reactor graceful stop.- Specified by:
