| Compares two iterators for inequality. | |
An unidirectional iterator for iterating over characters in a string. The TextIterator uses a TextEncoding object to work with multi-byte character encodings like UTF-8. Characters are reported in Unicode.
Example: Count the number of UTF-8 characters in a string.
UTF8Encoding utf8Encoding; std::string utf8String("...."); TextIterator it(utf8String, utf8Encoding); TextIterator end(utf8String); int n = 0; while (it != end) { ++n; ++it; }
NOTE: When an UTF-16 encoding is used, surrogate pairs will be reported as two separate characters, due to restrictions of the TextEncoding class.

| Poco::TextIterator::TextIterator | ( | const std::string::const_iterator & | begin, |
| const std::string::const_iterator & | end, | ||
| const TextEncoding & | encoding | ||
| ) |
Creates a TextIterator for the given string. The encoding object must not be deleted as long as the iterator is in use.

Creates a TextIterator for the given range. The encoding object must not be deleted as long as the iterator is in use.
