Overview

SimpleXMIECoreInstantiator demonstrates the usage of the DefaultXMLInstantiator. It can be used to instantiate an ECore model from an XMI description produced by Enterprise Architect.

Note however, that this is not the recommended way to read an EA model. See EAInstantiatorTest for the clean way to do this.

This example shows how arbitrary XML content can be used to instantiate an implicit metamodel. The resulting model is transformed into a simple ECore model.

See XMLInstantiatorTest for an example of how to use this class.
