BloombergLP::ball::LoggerManager::initSingleton

Initialize the logger manager singleton having the specified observer that receives published log records. Optionally specify a configuration describing how the singleton should be configured. If configuration is not specified, a default constructed LoggerManagerConfiguration object is used. Optionally specify a globalAllocator used to supply memory. If globalAllocator is 0, the currently installed global allocator is used. Return a non-const reference to the logger manager singleton. 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.
