Class TypeContext

java.lang.Object

de.uni_hildesheim.sse.translation.TypeContext

All Implemented Interfaces:

net.ssehub.easy.varModel.model.datatypes.IResolutionScope

public class TypeContext
extends java.lang.Object
implements net.ssehub.easy.varModel.model.datatypes.IResolutionScope

Defines a type context which consists of all variables defined in a project and additionally variables which can be added to the context in a layered manner. While IVML currently may not really require layered type contexts (shadowing variables), we just introduce it here for future use. The typical use is context.pushLayer(); context.addToContext(...); try { // resolve some types or expressions } catch (TranslatorException e) { throw e; } finally { context.popLayer(); } Please note that layers must properly be cleared (popLayer() . Further, a type context provides a resolution scope for its implicit definitions (without providing interfaces or a name).
This class provides support for sorting elements on project level as well as on compound level according to the input.
