Detailed Description

template<class CHAR>
class ACE_String_Base_Const_Iterator< CHAR >

Const iterator class for the ACE_String_Base class.

This class is an implementation of an iterator that allows client applications it iterator over the contents of a string. Currently, now this iterator fall under the std::bidirectional_iterator_tag category. Future versions of the class will support the operations of std::random_access_iterator_tag.
