After parsing the source files from any language, Sonargraph creates a system-based logical model based on the parser model which correspond to following diagram:
The system-based logical model is constructed in a way that the mapping from physical elements to logical elements occurs in the internal and external scopes separately meaning that the following conditions will be met:
-
Given a physical element "abc" inside a module of the user code and a physical element "abc" inside the external elements, there will be a logical element "abc" belonging to the InternalLogicalNamespaceRoot and another logical element "abc" belonging to the ExternalLogicalNamespaceRoot in the system-based logical model.
-
Given a physical element "abc" inside a module X of the user code and a physical element "abc" inside the module Y also in the user code, there will be a single logical element "abc" belonging to the InternalLogicalNamespaceRoot in the system-based logical model.
