All Implemented Interfaces:

Component, Forkable, Initializer, MultiFactory

public class JAtom

extends LazyComponent

implements MultiFactory, Initializer

Runtime atom component. Initialisation issues are dealt with by the LazyComponent implementation. Provides the basic behaviour of a MultiFactory too: holds a set of implementation alternatives.

newObject

public java.lang.Object newObject(Context _c,
                                  int _alternative,
                                  Instanciable _instance)
                           throws JonathanException

Implementation of the MultiFactory interface's newObject method. Returns a new instance of the atom's implementation alternative whose ID is _alternative.

Specified by:

newObject in interface MultiFactory

Parameters:

_c - where the instanciation parameters are found

_alternative - the alternative to instantiate

_instance - the method's caller.

Returns:

an new _alternative's instance

Throws:

JonathanException - if something goes wrong.

initialize

public void initialize(java.lang.Object _obj,
                       Context _c,
                       int _alternative)
                throws JonathanException

Implementation of the Initializer interface's initialize method. Initializes an instance of the atom's implementation alternative whose ID is _alternative by calling its setters.

Specified by:

initialize in interface Initializer

Parameters:

_obj - the object to initialize

_c - where the initialisation parameters are found

_alternative - the alternative to instantiate

Throws:

JonathanException - if something goes wrong.

initialize

protected final void initialize()

JAtom specific initialization code. Instantiates the JAtom's own value. Used internally by LazyComponent.

Specified by:

initialize in class LazyComponent
