Model Creation Factory

Overview

• As mentioned in Dev Doc Palette, the palette requires a model creation factory to support the creation tools. The factory's constructor requires the class to be created.
• EMF provides factories to generate instances of elements.
• EMF provides one factory per package.
• Throughout our application, we frequently have to generate new instances of objects.

seg.jUCMNav.model.ModelCreationFactory

• Central location to obtain new model element instances
• static method to obtain new objects instantly
• initializes model elements in a uniform fashion.
• usage example:

OrFork newOrFork = (OrFork) ModelCreationFactory.getNewObject(getUrnspec(), OrFork.class);

• requires an instance of a URNspec to be able to give an adequate id and unique name, if relevant.
• Use this method for all model elements, except URNspec which has its own getNewURNspec()
• Overloaded method has third argument for passing a type integer, to preset the type for stubs and components
