Overview

This package provides input streams vaguely inspired by C++ istream. In addition to C++-like methods such as extract(), isGood(), peek(), putback(), they provide convenenience methods such as extractUntil() or extractRegexp().

The class StringInputStream is for strings where one byte corresponds to one character, auch as ASCII or ISO-8859, while MbStringInputStream supports multibyte character sets such as UTF-8. The former should be preferred if applicable because it is faster.

See the doxygen documentation for details.
