Method Detail

store

public static void store(FailSafe data)
                  throws java.lang.Exception

Manages the store information of the class.

Parameters:

data - The FailSafe instance to manage

Throws:

java.lang.Exception - if the files cannot be stored correctly.

load

public static void load(FailSafe data)
                 throws java.lang.Exception

Manages all load information of the class.

Parameters:

data - The FailSafe instance to manage

Throws:

java.lang.Exception - if the files cannot be loaded correctly.

load

public static FailSafe load(java.lang.Class c)
                     throws java.lang.Exception

Manages all load information of the class.

As this method does not use initialization data, it is preferred to use it only with classes implementing the Singleton pattern.

Parameters:

c - The class to load

Returns:

An initialized instance of the class

Throws:

java.lang.Exception - In case of execution error

load

public static FailSafe load(java.lang.Class c,
                            java.util.Map map)
                     throws java.lang.Exception

Manages all load information of the class.

The map parameter will be used as the argument for the constructor. If no appropriate constructor is found, it will fall back to the "no-argument" version.

Parameters:

c - The class to load

map - The map to pass to the constructor

Returns:

An initialized instance of the class

Throws:

java.lang.Exception - In case of execution error

load

public static FailSafe load(java.lang.Class c,
                            java.lang.Object obj)
                     throws java.lang.Exception

Manages all load information of the class.

The object parameter will be used as the argument for the constructor. The object must be exactly of the same class than the expected constructor parameter. If no appropriate constructor is found, it will fall back to the "no-argument" version.

Parameters:

c - The class to load

obj - The object to pass to the constructor

Returns:

An initialized instance of the class

Throws:

java.lang.Exception - In case of execution error

delete

public static void delete(FailSafe fs)
                   throws java.lang.Exception
