BloombergLP::ball::LoggerManagerScopedGuard::LoggerManagerScopedGuard

Create a scoped guard that will create the logger manager singleton having the specified observer that receives published log records and the specified configuration of defaults and attributes. Optionally specify a globalAllocator used to supply memory. If globalAllocator is 0, the currently installed global allocator is used. This method has no effect (aside from logging a warning) if the logger manager singleton already exists. The behavior is undefined if observer is 0, goes out of scope, or is otherwise destroyed. Note that on destruction, this scoped guard will destroy the logger manager singleton, if the singleton exists at that time.
