MEMBER FUNCTION DOCUMENTATION

QNPStream::QNPStream ( QNPInstance * in,const char * mt, _NPStream * st, bool se )
Creates a stream. Plugins should not call this, but rather QNPInstance::newStream() if a stream is required.

QNPStream::~QNPStream ()
Destroys the stream.

bool QNPStream::complete () const
Returns TRUE if the stream has received all the data from the source.

uint QNPStream::end () const
Returns the length of the stream (???).

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.

void QNPStream::requestRead ( int offset, uint length )
Requests the given section of the stream be sent to the QNPInstance::write() function of the instance() of this stream.

bool QNPStream::seekable () const
Returns TRUE if the stream is seekable.

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 data to the stream.

void QNPStream::setComplete ( bool y )
For internal use only.

void QNPStream::setOkay ( bool y )
For internal use only.
