1\section{\class{wxDataOutputStream}}\label{wxdataoutputstream}
2
3This class provides functions that write binary data types in a
4portable way. Data can be written in either big-endian or little-endian
5format, little-endian being the default on all architectures.
6
7If you want to write data to text files (or streams) use
8\helpref{wxTextOutputStream}{wxtextoutputstream} instead.
9
10The << operator is overloaded and you can use this class like a standard
11C++ iostream. See \helpref{wxDataInputStream}{wxdatainputstream} for its
12usage and caveats.
13
14See also \helpref{wxDataInputStream}{wxdatainputstream}.

23
24\func{}{wxDataOutputStream}{\param{wxOutputStream\&}{ stream}}
25
26\func{}{wxDataOutputStream}{\param{wxOutputStream\&}{ stream}, \param{wxMBConv\&}{ conv = wxMBConvUTF8}}
27
28Constructs a datastream object from an output stream. Only write methods will
29be available. The second form is only available in Unicode build of wxWindows.
30
31\wxheading{Parameters}
32
33\docparam{stream}{The output stream.}
34
35\docparam{conv}{Charset conversion object object used to encoding Unicode
36strings before writing them to the stream
37in Unicode mode (see \helpref{wxDataOutputStream::WriteString}{wxdataoutputstreamwritestring}
38documentation for detailed description). Note that you must not destroy
39{\it conv} before you destroy this wxDataOutputStream instance! It is
40recommended to use default value (UTF-8).}
41
42\membersection{wxDataOutputStream::\destruct{wxDataOutputStream}}
43
44\func{}{\destruct{wxDataOutputStream}}{\void}
45
46Destroys the wxDataOutputStream object.
47
48\membersection{wxDataOutputStream::BigEndianOrdered}
49
50\func{void}{BigEndianOrdered}{\param{bool}{ be\_order}}
51
52If {\it be\_order} is TRUE, all data will be written in big-endian
53order, e.g. for reading on a Sparc or from Java-Streams (which
54always use big-endian order), otherwise data will be written in
55little-endian order.
56
57\membersection{wxDataOutputStream::Write8}
58
59\func{void}{Write8}{{\param wxUint8 }{i8}}
60
61Writes the single byte {\it i8} to the stream.
62
63\membersection{wxDataOutputStream::Write16}
64
65\func{void}{Write16}{{\param wxUint16 }{i16}}
66
67Writes the 16 bit integer {\it i16} to the stream.
68
69\membersection{wxDataOutputStream::Write32}
70
71\func{void}{Write32}{{\param wxUint32 }{i32}}
72
73Writes the 32 bit integer {\it i32} to the stream.
74
75\membersection{wxDataOutputStream::WriteDouble}
76
77\func{void}{WriteDouble}{{\param double }{f}}
78
79Writes the double {\it f} to the stream using the IEEE format.
80
81\membersection{wxDataOutputStream::WriteString}\label{wxdataoutputstreamwritestring}
82
83\func{void}{WriteString}{{\param const wxString\&}{string}}
84
85
86Writes {\it string} to the stream. Actually, this method writes the size of
87the string before writing {\it string} itself.
88
89In ANSI build of wxWindows, the string is written to the stream in exactly
90same way it is represented in memory. In Unicode build, however, the string
91is first converted to multibyte representation with {\it conv} object passed
92to stream's constructor (consequently, ANSI application can read data
93written by Unicode application, as long as they agree on encoding) and this
94representation is written to the stream. UTF-8 is used by default.
