Interface Model.ElementFactory

All Known Implementing Classes:

AbstractElementFactory

Enclosing interface:

Model

public static interface Model.ElementFactory

A factory object responsible for creating the correct ModelElement subclass object for a NSUML MModelElement encountered during loading. It is also responsible for creating a copy of itself set up to create elements in a specific Model. This saves having separate factory-factories, and is an example of the GoF Prototype pattern.

Method Detail

createElement

public ModelElement createElement(ru.novosoft.uml.foundation.core.MModelElement me,
                                  ModelElement parent)

Create the correct ModelElement for me.

Parameters:

me - the model element being loaded

parent - the element which will contain the new ModelElement

Returns:

the new ModelElement, or null if this ElementFactory cannot create one for me

createCopy

public Model.ElementFactory createCopy(Model model)

Create the correct ElementFactory for model.

Parameters:

model - the model being loaded

Returns:

the new ElementFactory. If the ElementFactory needs no knowledge of the Model to which it belongs, then this could be the same instance, but this is probably a rare situation. This method will be called before the Model is fully initialised, so it should not do anything with the Model other than store a reference to it.
