Public Member Functions | |
| SubIteratorBase (const tref &) | |
| const iref & | elem () const |
| Returns current element. | |
| cp_rettype | pelem () const |
| Returns current element. Implements SubIterator's pelem(). | |
| unsigned int | num_iter () const |
| Returns a number of iterations (number of elements in a set over which to iterate). | |
| void | init () |
| Initializes the iterator. | |
| SubIterator & | operator++ () |
| Iterates to the next element. Only prefix form is provided. | |
| operator int () const | |
| This is used to check whether current element exists. Returns 1 if it does. | |

Detailed Description
template<class T, template< class > class Tr = Policy>
class libint2::SubIteratorBase< T, Tr >
SubIteratorBase<T> provides a base class for a sub-iterator class for T.
It iterates through T as if it were a set of some data of type T::iter_type. Traits of class T (ordering of T::iter_type, etc.) are provided by Tr<T>.
The documentation for this class was generated from the following files:
- iter.h
- iter.cc
