Rose::RecursionCounter Struct Reference

Description

Track recursion depth in a function.

Use it like this:

boost::tribool someAnalysis() {
    static size_t depth = 0;
    RecursionCounter recursion(depth);
    if (depth > 5) // some arbitrary limit
        return boost::tribool::indeterminate;
    ...
}

You might ask, "Why use this class instead of just saying <code>++depth</code> and <code>--depth</code>?". If you use this class you don't have to remember to decrement the depth, especially if you (or someone else) adds additional return statements later, or if anything can throw and exception.
