1 \section{\class{wxDataStream}}\label{wxdatastream}
2
3 This class provides functions that read and write integers or double in a
4 portable way. So, a file written by an Intel processor can be read by a
5 Sparc or anything else.

9 \membersection{wxDataStream::wxDataStream}\label{wxdatastreamconstr}
10
11 \func{}{wxDataStream}{\param{istream\&}{ stream}}
12
13 Constructs a datastream object from a C++ input stream. Only read methods will
14 be available.
15
16 \wxheading{Parameters}
17
18 \docparam{stream}{The C++ input stream.}
19
20 \func{}{wxDataStream}{\param{istream\&}{ stream}}
21
22 Constructs a datastream object from a C++ input stream. Only read methods will
23 be available.
24
25 \wxheading{Parameters}
26
27 \docparam{stream}{The C++ input stream.}
28
29 \membersection{wxDataStream::\destruct{wxDataStream}}
30
31 \func{}{\destruct{wxDataStream}}{\void}
32
33 Destroys the wxDataStream object.
34
35 \membersection{wxDataStream::Read8}
36
37 \func{unsigned char}{Read8}{\void}
38
39 Reads a single byte from the stream.
40
41 \membersection{wxDataStream::Read16}
42
43 \func{unsigned short}{Read16}{\void}
44
45 Reads a 16 bit integer from the stream.
46
47 \membersection{wxDataStream::Read32}
48
49 \func{unsigned long}{Read32}{\void}
50
51 Reads a 32 bit integer from the stream.
52
53 \membersection{wxDataStream::ReadDouble}
54
55 \func{double}{ReadDouble}{\void}
56
57 Reads a double (IEEE encoded) from the stream.
58
59 \membersection{wxDataStream::ReadString}
60
61 \func{wxString}{wxDataStream::ReadString}{\void}
62
63 Reads a string from a stream. Actually, this function first reads a byte
64 specifying the length of the string (without the last null character) and then
65 reads the string.
66
67 \membersection{wxDataStream::ReadLine}
68
69 \func{wxString}{wxDataStream::ReadLine}{\void}
70
71 Reads a line from the stream. A line is a string which ends with \\n or \\r\\n.
72
73 \membersection{wxDataStream::Write8}
74
75 \func{void}{wxDataStream::Write8}{{\param unsigned char }{i8}}
76
77 Writes the single byte {\it i8} to the stream.
78
79 \membersection{wxDataStream::Write16}
80
81 \func{void}{wxDataStream::Write16}{{\param unsigned short }{i16}}
82
83 Writes the 16 bit integer {\it i16} to the stream.
84
85 \membersection{wxDataStream::Write32}
86
87 \func{void}{wxDataStream::Write32}{{\param unsigned long }{i32}}
88
89 Writes the 32 bit integer {\it i32} to the stream.
90
91 \membersection{wxDataStream::WriteDouble}
92
93 \func{void}{wxDataStream::WriteDouble}{{\param double }{f}}
94
95 Writes the double {\it f} to the stream using the IEEE format.
96
97 \membersection{wxDataStream::WriteString}
98
99 \func{void}{wxDataStream::WriteString}{{\param const wxString\& }{string}}
100
101 Writes {\it string} to the stream. Actually, this method writes the size of
102 the string before writing {\it string} itself.
103
104 \membersection{wxDataStream::WriteLine}
105
106 \func{void}{wxDataStream::WriteLine}{{\param const wxString\& }{string}}
107
108 Writes {\it string} as a line. Depending on the operating system, it adds
109 \\n or \\r\\n.
