Changeset 8423


Ignore:
Timestamp:
May 9, 2011, 5:06:49 AM (13 years ago)
Author:
rgrieder
Message:

Added and incorporated new class DestructionHelper: instead of doing the destruction of certain singletons implicitly via scoped_ptrs and ScopeGuards, use a method named destroy() that essentially achieves the same, but makes the destruction sequence obvious.
