Examples of org.eclipse.emf.ecore.EFactory

org.eclipse.emf.ecore.EFactory
A representation of the model object 'EFactory'.
A factory is responsible for {@link #create creating} class instances,and for converting data type instances {@link #convertToString to} and {@link #createFromString from} String.

The following features are supported:
- {@link org.eclipse.emf.ecore.EFactory#getEPackage EPackage}
@see org.eclipse.emf.ecore.EcorePackage#getEFactory() @model @generated

    }
  }
