Inequality operator.

Comparison of iterators.

Parameters
toCompareThe gum::BijectionIteratorSafe to compare.
Returns
Returns true if they differ.

returns a new iterator

If the iterator points to gum::Bijection::end(), the resulting iterator also points to gum::Bijection::end(). If there are nb or fewer elements to parse to reach the end of the gum::Bijection, then the resulting iterator points to gum::Bijection::end().

moves the iterator by nb elements

If the iterator points to gum::Bijection::end(), nothing is done. If there are nb or fewer elements to parse to reach the end of the bijection, then this method makes the iterator point to gum::Bijection::end().

Parameters
nbThe number of steps by wich the iterator moves.
Returns
Returns this gum::BijectionIterator.
