Made wxBufferedOutputStream call Sync() in
the destructor and SeekO().
Documented this.
Use buffered streams in wxImage. Seems to
significantly speed-up the sample.

\section{\class{wxBufferedInputStream}}\label{wxbufferedinputstream}
|
|
|
|
This stream acts as a cache. It caches the bytes read from the specified
|
|
input stream (See \helpref{wxFilterInputStream}{wxfilterinputstream}).
|
|
It uses wxStreamBuffer and sets the default in-buffer size to 1024 bytes.
|
|
This class may not be used without some other stream to read the data
|
|
from (such as a file stream or a memory stream).

\section{\class{wxBufferedOutputStream}}\label{wxbufferedoutputstream}
|
|
|
|
This stream acts as a cache. It caches the bytes to be written to the specified
|
|
output stream (See \helpref{wxFilterOutputStream}{wxfilteroutputstream}). The
|
|
datas are only written when the cache is full, when the buffered stream is
|
|
destroyed or when calling SeekO().
|
|
|
|
This class may not be used without some other stream to write the data
|
|
to (such as a file stream or a memory stream).

\membersection{wxBufferedOutputStream::wxBufferedOutputStream}
|
|
|
|
\func{}{wxBufferedOutputStream}{\param{const wxOutputStream\&}{ parent}}
|
|
|
|
Creates a buffered stream using a buffer of a default size of 1024 bytes for cashing
|
|
the stream {\it parent}.
|
|
|
|
\membersection{wxBufferedOutputStream::\destruct{wxBufferedOutputStream}}
|
|
|
|
\func{}{\destruct{wxBufferedOutputStream}}{\void}
|
|
|
|
Destructor. Calls Sync() and destroys the internal buffer.
|
|
|
|
\membersection{wxBufferedOutputStream::SeekO}
|
|
|
|
\func{off\_t}{SeekO}{\param{off\_t}{ pos}, \param{wxSeekMode}{ mode}}
|
|
|
|
Calls Sync() and changes the stream position.
|
|
|
|
\membersection{wxBufferedOutputStream::Sync}
|
|
|
|
\func{void}{Sync}{\void}
|
|
|
|
Flushes the buffer and calls Sync() on the parent stream.
