DESCRIPTION

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.  

QNPStream::~QNPStream ()

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.
