java.lang.Object

fr.sii.ogham.sms.sender.impl.cloudhopper.session.BaseSessionHandlingStrategy

All Implemented Interfaces:

Cleanable, SessionHandlingStrategy

Direct Known Subclasses:

AlwaysNewSessionStrategy, KeepSessionAliveStrategy, MayReuseSessionStrategy

public abstract class BaseSessionHandlingStrategy
extends Object
implements SessionHandlingStrategy

Base class for different session handling strategies.

It provides useful methods to initialize a client and a session. It provides a method to connect (bind) to the SMSC with retry handling. It also provides method to cleanup. The implementations can then use this methods as they wish.

Method Detail

initSession

protected void initSession()
                    throws SmppException

Initializes a new session only if session doesn't exist (is null).

A SmppClient instance must exist (either using initClient() or by manually creating it). The same SmppClient may be used several times for different sessions.

The creation of a session is done by calling connect(SmppClient).

Throws:

SmppException - when session couldn't be created

connect

protected com.cloudhopper.smpp.SmppSession connect(com.cloudhopper.smpp.SmppClient client)
                                            throws SmppException

Connect the client to the SMSC using a SmppClient.bind(com.cloudhopper.smpp.SmppSessionConfiguration, com.cloudhopper.smpp.SmppSessionHandler) request.

The configured retry strategy is used to send the bind request to the server i.e. several attempts may be done.

Parameters:

client - the client used to send to bind command

Returns:

the created session

Throws:

SmppException - when the session couldn't be bound

initClient

protected void initClient()

Create a SmppClient instance of not existing (is null).

destroySession

protected void destroySession()

Send an unbind command to the server to properly close the session, close the session and cleanup everything related to the session. The current session is set to null.

destroyClient

protected void destroyClient()

Destroy (cleanup everything) the client. The client is set to null.
