Member Function Documentation

ASCString MemoryStreamCopy::getLocation (   )  [virtual]

returns the location of the stream. This may be a complete english sentence describing how the stream (usually a file) can be found. Should only be used for informing the user. Reimplemented from tnstream. Definition at line 598 of file basestrm.cpp. References tnstream::devicename.

int MemoryStreamCopy::getPosition (  void   )  [inline]

Definition at line 176 of file basestrm.h. Referenced by stream_seek().

int MemoryStreamCopy::getSize (  void   )  [inline, virtual]

returns the size of the stream or -1 if the stream does not have a size Reimplemented from tnstream. Definition at line 177 of file basestrm.h. Referenced by stream_seek().

int MemoryStreamCopy::readdata (  void *  buf, int  size, bool  excpt = true )  [virtual]

Reads data from the stream. Parameters: buf  the buffer which the data is written to size  the number of bytes which should be read excpt  If true the operation will throw an exception if the desired number of bytes cannot be read. Returns: the number of bytes which were read. Implements tnstream. Definition at line 615 of file basestrm.cpp. References tnstream::getDeviceName(), and PolygonTriangulationLibrary::tr. Referenced by stream_read().

void MemoryStreamCopy::seek (  int  newpos  )  [virtual]

Sets the stream pointer to a new location. An exception is thrown if the stream does not support seeking. Reimplemented from tnstream. Definition at line 635 of file basestrm.cpp. References tnstream::getDeviceName(). Referenced by stream_seek().

void MemoryStreamCopy::writedata (  const void *  buf, int  size )  [virtual]

writes data to the stream Parameters: buf  pointer to the buffer size  the number of bytes which are going to be written Implements tnstream. Definition at line 610 of file basestrm.cpp. References tnstream::getDeviceName(), tnstream::reading, and tnstream::writing.
