| * Requests a connection to a remote host. |
| * <p> |
| * 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 |
| * {@link Future} interface. |
| * <p> |
| * There are several parameters one can use to exert a greater control over |
| * the process of session initialization: |
| * <p> |
| * A non-null local socket address parameter can be used to bind the socket |
| * to a specific local address. |
| * <p> |
| * 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. |
| * <p> |
| * 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 |
| * {@link FutureCallback} instance to get notified of events related |
| * to session requests, such as request completion, cancellation, failure or |
| * timeout. |
| * |
| * @param remoteEndpoint name of the remote host. |
| * @param remoteAddress remote socket address. |
| * @param localAddress local socket address. Can be {@code null}, |
| * in which can the default local address and a random port will be used. |
| * @param timeout connect timeout. |
| * @param attachment the attachment object. Can be {@code null}. |
| * @param callback interface. Can be {@code null}. |
| * @return session request object. |
