BaseLib::ConfigTree::ValueIterator< ValueType > Class Template Reference

Detailed Description

template<typename ValueType>
class BaseLib::ConfigTree::ValueIterator< ValueType >

A wrapper around a Boost Iterator for iterating over ranges of values.

The methods of this class tell the associated (parent) ConfigTree object when a setting has been parsed.
