The metafunction Iterator returns the iterator type for a given container type.

The following lines show a loop through str in the standard library style:

Seqan offers an alternative style for accessing iterators that avoids operators.
Note that the functions goBegin and atEnd do net get str as arguments,
because it2 is a rooted iterator.
The following loop increments each character in str :

This is a reverse loop through str .
Note that goPrevious is called before the value of it2 is accessed,
because the end position of a container is the position behind the last item in the container:

Another (write only) way to access the value of an iterator is assignValue:
