BloombergLP::ball::LoggerManagerCategoryIter::LoggerManagerCategoryIter

Create an iterator providing non‐modifiable access to the categories maintained by the specified loggerManager that is initialized to refer to the first category in the sequence of categories in the registry of loggerManager, if one exists, and is initialized to be invalid otherwise. The order of iteration is undefined. The behavior is undefined unless the lifetime of loggerManager is at least as long as the lifetime of this iterator.
