Method Detail

create

public static MiddleEnd create(BackendTypesystem ts,
                               java.util.List<LanguageSpecificMiddleEnd> languageHandlers)

This method creates a MiddleEnd instance based on an explicitly provided list of handlers. It works without OSGi.

createFromExtensions

public static MiddleEnd createFromExtensions(BackendTypesystem ts,
                                             java.util.Map<java.lang.Class<?>,java.lang.Object> specificParams)

This method creates a middle end based on the handlers registered with the extension point. It relies on OSGi and makes use of the Eclipse extension registry.
The map with "specific params" is used to initialize the contributed middle ends. The key must be the class implementing the LanguageSpecificMiddleEnd interface and contributed via the extension point.
