Changeset 5850 for code/branches/core5/src/libraries/util

Timestamp:

Oct 1, 2009, 11:44:53 AM (15 years ago)

Author:

Message:

Moved the singleton creation/destruction mess to the Core class by using just two possible Scopes:

• ScopeID::Root for singletons that may always persists
• ScopeID::Graphics for singletons that only work when graphics was loaded

Location:

code/branches/core5/src/libraries/util

Files:

• Scope.h (modified) (4 diffs)
• ScopedSingleton.h (modified) (3 diffs)
