Detailed Description

template<class T, class Key = word, class Hash = string::hash>
class Foam::HashTable< T, Key, Hash >::iteratorBase

The iterator base for HashTable.

Note: data and functions are protected, to allow reuse by iterator and prevent most external usage. iterator and const_iterator have the same size, allowing us to reinterpret_cast between them (if desired)
