\section{\class{wxDataOutputStream}}\label{wxdataoutputstream}

This class provides functions that write binary data types in a
portable way. Data can be written in either big-endian or litte-endian
format, little-endian being the default on all architectures.

If you want to write data to text files (or streams) use 
\helpref{wxTextOutputStream}{wxtextoutputstream} instead.

The << operator is overloaded and you can use this class like a standard 
C++ iostream. See \helpref{wxDataInputStream}{wxdatainputstream} for its 
usage and caveats.

See also \helpref{wxDataInputStream}{wxdatainputstream}.

\membersection{wxDataOutputStream::wxDataOutputStream}\label{wxdataoutputstreamconstr}

\func{}{wxDataOutputStream}{\param{wxOutputStream\&}{ stream}}

Constructs a datastream object from an output stream. Only write methods will
be available.

\wxheading{Parameters}

\docparam{stream}{The output stream.}

\membersection{wxDataOutputStream::\destruct{wxDataOutputStream}}

\func{}{\destruct{wxDataOutputStream}}{\void}

Destroys the wxDataOutputStream object.

\membersection{wxDataOutputStream::BigEndianOrdered}

\func{void}{BigEndianOrdered}{\param{bool}{ be\_order}}

If {\it be\_order} is TRUE, all data will be written in big-endian
order, e.g. for reading on a Sparc or from Java-Streams (which
always use big-endian order), otherwise data will be written in
little-endian order.
 
\membersection{wxDataOutputStream::Write8}

\func{void}{Write8}{{\param wxUint8 }{i8}}

Writes the single byte {\it i8} to the stream.

\membersection{wxDataOutputStream::Write16}

\func{void}{Write16}{{\param wxUint16 }{i16}}

Writes the 16 bit integer {\it i16} to the stream.

\membersection{wxDataOutputStream::Write32}

\func{void}{Write32}{{\param wxUint32 }{i32}}

Writes the 32 bit integer {\it i32} to the stream.

\membersection{wxDataOutputStream::WriteDouble}

\func{void}{WriteDouble}{{\param double }{f}}

Writes the double {\it f} to the stream using the IEEE format.

\membersection{wxDataOutputStream::WriteString}

\func{void}{WriteString}{{\param const wxString\& }{string}}

Writes {\it string} to the stream. Actually, this method writes the size of
the string before writing {\it string} itself.
