Changeset 9646 for code/branches/core6/src/libraries

Timestamp:

Aug 13, 2013, 11:35:26 PM (11 years ago)

Author:

Message:

implemented new concept to initialize the class hierarchy: each identifier is initialized individually by creating an object of the corresponding class. identifiers of abstract classes must be told explicitly about their direct parents. this allows to build the class tree correctly also for complicated setups like multiple inheritance of abstract classes.
