10.8. Factories and Packages

So far, we have looked at the interfaces and classes that correspond to the EClassifiers contained in an EPackage. In addition to these, EMF by default generates two interfaces, along with implementations, corresponding to the EPackage itself: a package and a factory.

The package provides some static constants and convenience methods for accessing the metadata for the classifiers defined in the EPackage, while the factory, as its name implies, allows for their instantiation.
