Detailed Description
An abstract iterator.
Extending types should provide a constructor that returns a pointer to a iterator_t that references a newly allocated iterator of the extending type. The iterator must be in the state it would be in after a call to reset.
Example usage:
use musica_foo_iterator, only : foo_iterator_t
class(iterator), pointer :: my_iterator
my_iterator => foo_iterator_t( ) ! can accept arguments if necessary
do while( my_iterator%next( ) )
some_function( my_iterator, ... ) ! use a function that uses a foo_iterator_t
end do
call my_iterator%reset( ) ! reset the iterator
do while( my_iterator%next( ) )
some_other_function( my_iterator, ... )
end do
deallocate( my_iterator )
