Detailed Description

template<class T>
class Ogre::ConstMapIterator< T >

Wraps iteration over a const map.

Remarks:

This class is here just to allow clients to iterate over an internal map of a class without having to have access to the map itself (typically to iterate you need both the iterator and the end() iterator to test for the end condition, which is messy). No updates are allowed through this interface, it is purely for iterating and reading.

Note that like STL iterators, these iterators are only valid whilst no updates are made to the underlying collection. You should not attempt to use this iterator if a change is made to the collection. In fact, treat this iterator as a transient object, do NOT store it and try to use it repeatedly.
