Class Configuration

java.lang.Object
  net.sourceforge.jdbdump.connect.Configuration

public class Configuration
extends java.lang.Object

This class is a Singleton, which purpose is to manage system's configuration data such as:

• authorization data of users allowed to use the system,
• configured connections to databases

Data is passed to/from a subclass of ConfigurationIO class, which gives great flexibility in choose of configuration data storage place and access methods.

Method Summary

void	addBackup(DatabaseBackupData dbd) Adds data about database backup to current configuration.
void	addDatabase(DatabaseConnectionData dcd) Adds data about database connection to current configuration.
java.lang.Object	clone() Prevents cloning the Configuration object, and therefore reduces the possibility of creating more than one object - we are avoiding such situations, becouse Configuration is implementing Singleton design pattern
java.lang.String	getBackupDir()
java.util.Hashtable<java.lang.String,DatabaseBackupData>	getBackups() Returns list of backuped databases
java.util.Hashtable<java.lang.String,DatabaseConnectionData>	getConnections() Returns list of configured database connections
java.lang.String	getEmail()
static Configuration	getInstance() This method is the only possibility to get an instance of class Configuration.
void	loadData() Loads configuration data to the Configuration object
void	removeBackup(DatabaseBackupData dbd) Removes data about database backup from current configuration.
void	removeBackup(java.lang.String title, java.lang.String date) Removes data about database backup from current configuration.
void	removeDatabase(DatabaseConnectionData dbc) Removes data about database connection from current configuration.
void	removeDatabase(java.lang.String title) Removes data about database connection from current configuration.
void	saveData() Saves configuration storred in the Configuration object.
boolean	setAutoload(boolean value) Changes value of autoload setting.
boolean	setAutosave(boolean value) Changes value of autosave setting.

Method Detail

getInstance

public static Configuration getInstance()
                                 throws java.lang.InstantiationException,
                                        java.lang.IllegalAccessException,
                                        java.lang.ClassNotFoundException,
                                        java.io.IOException

This method is the only possibility to get an instance of class Configuration. Aim for this limitation is to keep control on object creation.

Returns:

the Singleton Configuration object;

Throws:

java.lang.ClassNotFoundException

java.lang.IllegalAccessException

java.lang.InstantiationException

java.io.IOException

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Prevents cloning the Configuration object, and therefore reduces the possibility of creating more than one object - we are avoiding such situations, becouse Configuration is implementing Singleton design pattern

Overrides:

clone in class java.lang.Object

Throws:

java.lang.CloneNotSupportedException - if one tries to clone a Configuration object

setAutosave

public boolean setAutosave(boolean value)

Changes value of autoload setting.

Parameters:

value - new setting of the autoload flag.

Returns:

old value

See Also:

autoload, #reload()
