   5
   6 This stream acts as a cache. It caches the bytes read from the specified
   7 input stream (See \helpref{wxFilterInputStream}{wxfilterinputstream}).
   8 It uses wxStreamBuffer and sets the default in-buffer size to 1024 bytes.
   9 This class may not be used without some other stream to read the data
  10 from (such as a file stream or a memory stream).

  28
  29 This stream acts as a cache. It caches the bytes to be written to the specified
  30 output stream (See \helpref{wxFilterOutputStream}{wxfilteroutputstream}). The
  31 datas are only written when the cache is full, when the buffered stream is
  32 destroyed or when calling SeekO().

  34 This class may not be used without some other stream to write the data
  35 to (such as a file stream or a memory stream).

  56 \func{}{wxBufferedOutputStream}{\param{const wxOutputStream\&}{ parent}}

  58 Creates a buffered stream using a buffer of a default size of 1024 bytes for cashing
  59 the stream {\it parent}.
