TypeHierarchyResolver

Transitively RecordDeclaration nodes with their supertypes' records.

Supertypes are all interfaces a class implements and the superclass it inherits from (including all of their respective supertypes). The JavaParser provides us with initial info about direct ancestors' names. This pass then recursively maps those and their own supertypes to the correct RecordDeclaration (if available).

After determining the ancestors of a class, all inherited methods are scanned to find out which of them are overridden/implemented in the current class. See FunctionDeclaration.getOverriddenBy

Attention: Needs to be run before other analysis passes, as it triggers a type refresh. This is needed e.g. for de.fraunhofer.aisec.cpg.graph.TypeManager.getCommonType to be re-evaluated at places where it is crucial to have parsed all RecordDeclarations. Otherwise, type information in the graph might not be fully correct
