QNPStream - Stream of data provided to a QNPInstance by the browser
This class is part of the Qt Netscape Extension. #include <qnp.h> Public Members ~QNPStream () const char * url () const uint end () const uint lastModified () const const char * type () const bool seekable () const bool okay () const bool complete () const void requestRead ( int offset, uint length ) int write ( int len, void * buffer ) QNPInstance * instance () QNPStream ( QNPInstance * in, const char * mt, _NPStream * st, bool se )
This class is defined in the Qt Netscape Extension, which can be found in the qt/extensions directory. It is not included in the main Qt API. The QNPStream class provides a stream of data provided to a QNPInstance by the browser. Note that this is neither a QTextStream nor a QDataStream. See also QNPInstance::write() and QNPInstance::newStreamCreated().
MEMBER FUNCTION DOCUMENTATION
QNPStream::QNPStream ( QNPInstance * in, const char * mt, _NPStream * st, bool se )
Creates a stream. Plugins should not call this; they should call QNPInstance::newStream() if they need a stream. Takes a QNPInstance in, MIME type mt, a pointer to an _NPStream st and a seekable flag se.
Destroys the stream.
bool QNPStream::complete () const
Returns TRUE if the stream has received all the data from the source; otherwise returns FALSE.
uint QNPStream::end () const
Returns the length of the stream in bytes. The function might return 0 for streams of unknown length.
QNPInstance * QNPStream::instance ()
Returns the QNPInstance for which this stream was created.
uint QNPStream::lastModified () const
Returns the time when the source of the stream was last modified.
bool QNPStream::okay () const
Returns TRUE if no errors have occurred on the stream; otherwise returns FALSE.
void QNPStream::requestRead ( int offset, uint length )
Requests the section of the stream, of length bytes from offset, be sent to the QNPInstance::write() function of the instance() of this stream.
bool QNPStream::seekable () const
Returns TRUE if the stream is seekable; otherwise returns FALSE.
const char * QNPStream::type () const
Returns the MIME type of the stream.
const char * QNPStream::url () const
Returns the URL from which the stream was created.
int QNPStream::write ( int len, void * buffer )
Writes len bytes from buffer to the stream.
