Constructor & Destructor Documentation

openlsd.database.session.LSDDbAdmin.LSDDbAdmin	(	String	driver,
		String	server,
		String	user,
		String	passwd
	)

This version creates a default write enabled connection.

A this time, only one driver is possible! If a new driver is needed, then we need to create a new LSDDbSession object. Be aware that LSDDbSession.initialize should be call only once for each driver, whatever the number of LSDDbSession objects that could be created (=> need a hashtable for specific driver when created). Also, don't know if two drivers at the same time (two different LSDDbSession) is allowed by JDBC.

Parameters:

	driver
	server
	user
	passwd

openlsd.database.session.LSDDbAdmin.LSDDbAdmin	(	String	driver,
		String	server,
		String	user,
		String	passwd,
		boolean	write
	)

This version creates can create a read only connection if write is false.

A this time, only one driver is possible! If a new driver is needed, then we need to create a new LSDDbSession object. Be aware that LSDDbSession.initialize should be call only once for each driver, whatever the number of LSDDbSession objects that could be created (=> need a hashtable for specific driver when created). Also, don't know if two drivers at the same time (two different LSDDbSession) is allowed by JDBC.

Parameters:

	driver
	server
	user
	passwd
	write

openlsd.database.session.LSDDbAdmin.LSDDbAdmin	(	Connection	conn,
		boolean	isread
	)

Use a given connexion to create the context.

A this time, only one driver is possible! If a new driver is needed, then we need to create a new LSDDbSession object. Be aware that LSDDbSession.initialize should be call only once for each driver, whatever the number of LSDDbSession objects that could be created (=> need a hashtable for specific driver when created). Also, don't know if two drivers at the same time (two different LSDDbSession) is allowed by JDBC.

This version use given connection. typeDriver must be set before !

Parameters:

	conn
	isread
