Detailed Description

template<typename VAL, typename IT>
class shawn::DerefIterator< VAL, IT >

Convenience iterator wrapper to auto-dereference pointers.

Iterator wrapper that dereferences pointers at access.

Consider there is a vector in which Thing* pointers are stored for some reason, but the pointers are all non-Null

  vector<Thing*> things;

...then the vector can be treated like a vector<Thing>:

  for( DerefIterator< Thing, vector<Thing>::iterator > it=things.begin();
       it != things.end();
       ++it )
    {
       Thing& t = *it;
       it->method();
    }
