Class AbstractServerImplementation

java.lang.Object
  infoservice.mailsystem.central.server.AbstractServerImplementation

All Implemented Interfaces:

java.lang.Runnable

Direct Known Subclasses:

MailSystemServerImplementation

public abstract class AbstractServerImplementation
extends java.lang.Object
implements java.lang.Runnable

This is a generic implementation for handling client requests which have reached the server.

Field Summary

private boolean	m_alreadyInUse Stores whether this AbstractServerImplementation is already in use.
private SocketContainer	m_socketContainer Stores the SocketContainer which includes the Socket connected to the client and maybe some alternative datastreams.
private java.lang.Object	m_synchronizer This object is used for synchronization purposes to prevent using this server implementation more than once.

Constructor Summary

protected

AbstractServerImplementation() Creates a new AbstractServerImplementation.

Method Summary

protected SocketContainer	getSocketContainer() Returns the SocketContainer with the connection to the client.
protected abstract void	handleClientRequest() This method must be implemented by the children of this class.
void	run() This is the generic implementation for handling the connection.
void	setClientConnection(SocketContainer a_socketContainer) This will set the SocketContainer with the connection to the client.

Field Detail

m_socketContainer

private SocketContainer m_socketContainer

Stores the SocketContainer which includes the Socket connected to the client and maybe some alternative datastreams.

m_alreadyInUse

private boolean m_alreadyInUse

Stores whether this AbstractServerImplementation is already in use.

m_synchronizer

private java.lang.Object m_synchronizer

This object is used for synchronization purposes to prevent using this server implementation more than once.

Constructor Detail

AbstractServerImplementation

protected AbstractServerImplementation()

Creates a new AbstractServerImplementation. This constructor is called automatically from the children of this class. Only some initialization is done here.

Method Detail

setClientConnection

public final void setClientConnection(SocketContainer a_socketContainer)

This will set the SocketContainer with the connection to the client. This method must only be called from the ConnectionHandle class. It is called once before the handling-thread calls the run() method.

Parameters:

a_socketContainer - The SocketContainer with the connection to the client.

run

public final void run()

This is the generic implementation for handling the connection. It will check, whether everything is defined correctly and will then start the specific server implementation of the children of this class by calling the handleClientRequest() method.

Specified by:

run in interface java.lang.Runnable

getSocketContainer

protected final SocketContainer getSocketContainer()

Returns the SocketContainer with the connection to the client. This method can be called by children of this class, if they need access to the client connection.

Returns:

The SocketContainer with the connection to the client.

handleClientRequest

protected abstract void handleClientRequest()

This method must be implemented by the children of this class. The request handling must be done here. It's called automatically by the request-handling thread. After it has finished this method, the connection to the client is closed automatically.
