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.
