< p > This class is defined in the < b > TQt < a href = "netscape-plugin.html#Netscape" > Netscape< / a > Extension< / b > , which can be found in the < tt > qt/extensions< / tt > directory. It is not included in the main TQt API.

The TQNPStream class provides a stream of data provided to a < a href = "qnpinstance.html" > TQNPInstance< / a > by the browser.
< p >
< p > Note that this is neither a < a href = "tqtextstream.html" > TQTextStream< / a > nor a < a href = "tqdatastream.html" > TQDataStream< / a > .
< p > < p > See also < a href = "qnpinstance.html#write" > TQNPInstance::write< / a > () and < a href = "qnpinstance.html#newStreamCreated" > TQNPInstance::newStreamCreated< / a > ().

< h3 class = fn > < a name = "TQNPStream" > < / a > TQNPStream::TQNPStream ( < a href = "qnpinstance.html" > TQNPInstance< / a > * in, const char * mt, _NPStream * st, bool se )
< / h3 >
Creates a stream. Plugins should not call this; they should call
< a href = "qnpinstance.html#newStream" > TQNPInstance::newStream< / a > () if they need a stream.
< p > Takes a < a href = "qnpinstance.html" > TQNPInstance< / a > < em > in< / em > , MIME type < em > mt< / em > , a pointer to an
_NPStream < em > st< / em > and a seekable flag < em > se< / em > .
< h3 class = fn > < a name = "~TQNPStream" > < / a > TQNPStream::~TQNPStream ()
< / h3 >
Destroys the stream.
< h3 class = fn > bool < a name = "complete" > < / a > TQNPStream::complete () const
< / h3 >
Returns TRUE if the stream has received all the data from the
source; otherwise returns FALSE.
< h3 class = fn > uint < a name = "end" > < / a > TQNPStream::end () const
< / h3 >
Returns the length of the stream in bytes. The function might
return 0 for streams of unknown length.
< h3 class = fn > < a href = "qnpinstance.html" > TQNPInstance< / a > * < a name = "instance" > < / a > TQNPStream::instance ()
< / h3 >
< p > Returns the < a href = "qnpinstance.html" > TQNPInstance< / a > for which this stream was created.
< h3 class = fn > uint < a name = "lastModified" > < / a > TQNPStream::lastModified () const
< / h3 >
Returns the time when the source of the stream was last modified.
< h3 class = fn > bool < a name = "okay" > < / a > TQNPStream::okay () const
< / h3 >
Returns TRUE if no errors have occurred on the stream; otherwise
returns FALSE.
< h3 class = fn > void < a name = "requestRead" > < / a > TQNPStream::requestRead ( int offset, uint length )
< / h3 >
Requests the section of the stream, of < em > length< / em > bytes from < em > offset< / em > , be sent to the < a href = "qnpinstance.html#write" > TQNPInstance::write< / a > () function of the
< a href = "#instance" > instance< / a > () of this stream.
< h3 class = fn > bool < a name = "seekable" > < / a > TQNPStream::seekable () const
< / h3 >
Returns TRUE if the stream is seekable; otherwise returns FALSE.
< h3 class = fn > const char * < a name = "type" > < / a > TQNPStream::type () const
< / h3 >
Returns the MIME type of the stream.
< h3 class = fn > const char * < a name = "url" > < / a > TQNPStream::url () const
< / h3 >
Returns the URL from which the stream was created.
< h3 class = fn > int < a name = "write" > < / a > TQNPStream::write ( int len, void * buffer )
< / h3 >
Writes < em > len< / em > bytes from < em > buffer< / em > < em > to< / em > the stream.
