Detailed Description

An implementation of IStreamer for reading from binary streams (little endian format).

Constructor & Destructor Documentation

rovsoft::io::AsciiIStreamer::AsciiIStreamer (  std::istream *  in  )  throw (lib::NullPointerExceptionPtr)

Builds a AsciiIStreamer getting its input from istream in. This istream object to which in points to should be dynamically generated because it gets deleted in the destructor of this class. Parameters: in  The istream to read from. Exceptions: NullPointerExceptionPtr  if in is a null pointer.

rovsoft::io::AsciiIStreamer::~AsciiIStreamer (   )  [virtual]

Deletes the istream object if input is not a null pointer.

Member Function Documentation

bool rovsoft::io::AsciiIStreamer::endOfStream (   )  [virtual]

Test if we are at the end of a stream. Returns: true if the end is reached. (E.g. end of file) Todo: Make common base classes for ASCII IStreamer and Binary IStreamer and ASCII OStreamer and Binary OStreamer, that define an i/o stream and the method endOfStream(). Todo: If we need something special for TCP I/O streams, then maybe extend ASCII IO Streamer for this functionality. Maybe completely rework the hierarchie. Implements rovsoft::io::IStreamer.

void rovsoft::io::AsciiIStreamer::readArrayfromStream (  char *  array, int  length )  throw (IOExceptionPtr) [protected]
