Detailed Description

A subclass allowing for the safe generation and removal of prefixes.

Somewhere at the beginning of a block, create one of these objects, and it will appear as a prefix in LogStream output like deallog. At the end of the block, the prefix will automatically be removed, when this object is destroyed.

In other words, the scope of the object so created determines the lifetime of the prefix. The advantage of using such an object is that the prefix is removed whichever way you exit the scope – by continue, break, return, throw, or by simply reaching the closing brace. In all of these cases, it is not necessary to remember to pop the prefix manually using LogStream::pop. In this, it works just like the better known Threads::Mutex::ScopedLock class.
