Changeset 805 for code

Timestamp:

Feb 12, 2008, 4:24:14 PM (17 years ago)

Message:

Added two new classes:

• ClassManager, a helper class for ClassIdentifier
• IdentifierDistributor, a class that hopefully allows unique ClassIdentifiers even with several libraries

In a first try it seemed to work, but it needs more testing. At least it solved a problem I discovered yesterday with multiple Identifiers for the type "BaseObject" on windows.
