public class DefaultConnectingIOReactor extends Object
ConnectionInitiator Internally
this I/O reactor distributes newly created I/O session equally across multiple
I/O worker threads for a more optimal resource utilization and a better
I/O performance. Usually it is recommended to have one worker I/O reactor
per physical CPU core.| Constructor and Description |

ConnectionInitiator
Opening a connection to a remote host usually tends to be a time
consuming process and may take a while to complete. One can monitor and
control the process of session initialization by means of the
Future interface.
There are several parameters one can use to exert a greater control over the process of session initialization:
A non-null local socket address parameter can be used to bind the socket to a specific local address.
An attachment object can added to the new session's context upon initialization. This object can be used to pass an initial processing state to the protocol handler.
It is often desirable to be able to react to the completion of a session
request asynchronously without having to wait for it, blocking the
current thread of execution. One can optionally provide an implementation
FutureCallback instance to get notified of events related
to session requests, such as request completion, cancellation, failure or
timeout.
