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
use musica_iterator,                 only : 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 )
