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}.

31
32\func{}{wxDataOutputStream}{\param{wxOutputStream\&}{ stream}}
33
34\func{}{wxDataOutputStream}{\param{wxOutputStream\&}{ stream}, \param{const wxMBConv\&}{ conv = wxConvAuto()}}
35
36Constructs a datastream object from an output stream. Only write methods will
37be available. The second form is only available in Unicode build of wxWidgets.
38
39\wxheading{Parameters}
40
41\docparam{stream}{The output stream.}
42
43\docparam{conv}{Charset conversion object object used to encoding Unicode
44strings before writing them to the stream
45in Unicode mode (see \helpref{wxDataOutputStream::WriteString}{wxdataoutputstreamwritestring}
46documentation for detailed description). Note that you must not destroy
47{\it conv} before you destroy this wxDataOutputStream instance! It is
48recommended to use default value (UTF-8).}
49
50\membersection{wxDataOutputStream::\destruct{wxDataOutputStream}}\label{wxdataoutputstreamdtor}
51
52\func{}{\destruct{wxDataOutputStream}}{\void}
53
54Destroys the wxDataOutputStream object.
55
56\membersection{wxDataOutputStream::BigEndianOrdered}\label{wxdataoutputstreambigendianorder}
57
58\func{void}{BigEndianOrdered}{\param{bool}{ be\_order}}
59
60If {\it be\_order} is true, all data will be written in big-endian
61order, e.g. for reading on a Sparc or from Java-Streams (which
62always use big-endian order), otherwise data will be written in
63little-endian order.
64
65\membersection{wxDataOutputStream::Write8}\label{wxdataoutputstreamwrite8}
66
67\func{void}{Write8}{{\param wxUint8 }{i8}}
68
69Writes the single byte {\it i8} to the stream.
70
71\func{void}{Write8}{\param{const wxUint8 *}{buffer}, \param{size\_t }{size}}
72
73Writes an array of bytes to the stream. The amount of bytes to write is
74specified with the {\it size} variable.
75
76\membersection{wxDataOutputStream::Write16}\label{wxdataoutputstreamwrite16}
77
78\func{void}{Write16}{{\param wxUint16 }{i16}}
79
80Writes the 16 bit unsigned integer {\it i16} to the stream.
81
82\func{void}{Write16}{\param{const wxUint16 *}{buffer}, \param{size\_t }{size}}
83
84Writes an array of 16 bit unsigned integer to the stream. The amount of
8516 bit unsigned integer to write is specified with the {\it size} variable.
86
87\membersection{wxDataOutputStream::Write32}\label{wxdataoutputstreamwrite32}
88
89\func{void}{Write32}{{\param wxUint32 }{i32}}
90
91Writes the 32 bit unsigned integer {\it i32} to the stream.
92
93\func{void}{Write32}{\param{const wxUint32 *}{buffer}, \param{size\_t }{size}}
94
95Writes an array of 32 bit unsigned integer to the stream. The amount of
9632 bit unsigned integer to write is specified with the {\it size} variable.
97
98\membersection{wxDataOutputStream::Write64}\label{wxdataoutputstreamwrite64}
99
100\func{void}{Write64}{{\param wxUint64 }{i64}}
101
102Writes the 64 bit unsigned integer {\it i64} to the stream.
103
104\func{void}{Write64}{\param{const wxUint64 *}{buffer}, \param{size\_t }{size}}
105
106Writes an array of 64 bit unsigned integer to the stream. The amount of
10764 bit unsigned integer to write is specified with the {\it size} variable.
108
109\membersection{wxDataOutputStream::WriteDouble}\label{wxdataoutputstreamwritedouble}
110
111\func{void}{WriteDouble}{{\param double }{f}}
112
113Writes the double {\it f} to the stream using the IEEE format.
114
115\func{void}{WriteDouble}{\param{const double *}{buffer}, \param{size\_t }{size}}
116
117Writes an array of double to the stream. The amount of double to write is
118specified with the {\it size} variable.
119
120\membersection{wxDataOutputStream::WriteString}\label{wxdataoutputstreamwritestring}
121
122\func{void}{WriteString}{{\param const wxString\&}{string}}
123
124Writes {\it string} to the stream. Actually, this method writes the size of
125the string before writing {\it string} itself.
126
127In ANSI build of wxWidgets, the string is written to the stream in exactly
128same way it is represented in memory. In Unicode build, however, the string
129is first converted to multibyte representation with {\it conv} object passed
130to stream's constructor (consequently, ANSI application can read data
131written by Unicode application, as long as they agree on encoding) and this
132representation is written to the stream. UTF-8 is used by default.
