631f1bfe 1\section{\class{wxDataInputStream}}\label{wxdatainputstream}
4d1f281b 2
631f1bfe 3This class provides functions that read data types in a
4d1f281b
GL
4portable way. So, a file written by an Intel processor can be read by a
5Sparc or anything else.

4d1f281b 20
631f1bfe 21\func{}{wxDataInputStream}{\param{wxInputStream\&}{ stream}}
4d1f281b 22
631f1bfe 23Constructs a datastream object from an input stream. Only read methods will
4d1f281b
GL
24be available.
25
26\wxheading{Parameters}
27
631f1bfe 28\docparam{stream}{The input stream.}

631f1bfe 30\membersection{wxDataInputStream::\destruct{wxDataInputStream}}
4d1f281b 31
631f1bfe 32\func{}{\destruct{wxDataInputStream}}{\void}
4d1f281b 33
631f1bfe 34Destroys the wxDataInputStream object.

631f1bfe 36\membersection{wxDataInputStream::Read8}
4d1f281b
GL
37
38\func{unsigned char}{Read8}{\void}
39
40Reads a single byte from the stream.

631f1bfe 42\membersection{wxDataInputStream::Read16}
4d1f281b
GL
43
44\func{unsigned short}{Read16}{\void}
45
46Reads a 16 bit integer from the stream.
47
631f1bfe 48\membersection{wxDataInputStream::Read32}
4d1f281b
GL
49
50\func{unsigned long}{Read32}{\void}
51
52Reads a 32 bit integer from the stream.
53
631f1bfe 54\membersection{wxDataInputStream::ReadDouble}
4d1f281b
GL
55
56\func{double}{ReadDouble}{\void}
57
58Reads a double (IEEE encoded) from the stream.
59
40b480c3
JS
60\membersection{wxDataInputStream::ReadLine}
61
62\func{wxString}{wxDataInputStream::ReadLine}{\void}
63
64Reads a line from the stream. A line is a string which ends with \\n or \\r\\n.
65
631f1bfe 66\membersection{wxDataInputStream::ReadString}
4d1f281b 67
631f1bfe 68\func{wxString}{wxDataInputStream::ReadString}{\void}
4d1f281b 69
631f1bfe 70Reads a string from a stream. Actually, this function first reads a long integer
4d1f281b
GL
71specifying the length of the string (without the last null character) and then
72reads the string.

74\section{\class{wxDataOutputStream}}\label{wxdataoutputstream}
75
76This class provides functions that write data types in a
77portable way. So, a file written by an Intel processor can be read by a
78Sparc or anything else.

82\membersection{wxDataOutputStream::wxDataOutputStream}\label{wxdataoutputstreamconstr}
83
84\func{}{wxDataInputStream}{\param{wxOutputStream\&}{ stream}}
85
86Constructs a datastream object from an output stream. Only read methods will
87be available.

92
93\membersection{wxDataOutputStream::\destruct{wxDataOutputStream}}
94
95\func{}{\destruct{wxDataOutputStream}}{\void}
96
97Destroys the wxDataOutputStream object.

631f1bfe 101\func{void}{wxDataOutputStream::Write8}{{\param unsigned char }{i8}}
4d1f281b
GL
102
103Writes the single byte {\it i8} to the stream.
104
631f1bfe 105\membersection{wxDataOutputStream::Write16}
4d1f281b 106
631f1bfe 107\func{void}{wxDataOutputStream::Write16}{{\param unsigned short }{i16}}
4d1f281b
GL
108
109Writes the 16 bit integer {\it i16} to the stream.

4d1f281b 112
631f1bfe 113\func{void}{wxDataOutputStream::Write32}{{\param unsigned long }{i32}}
4d1f281b
GL
114
115Writes the 32 bit integer {\it i32} to the stream.

4d1f281b 118
631f1bfe 119\func{void}{wxDataOutputStream::WriteDouble}{{\param double }{f}}
4d1f281b
GL
120
121Writes the double {\it f} to the stream using the IEEE format.

631f1bfe 123\membersection{wxDataOutputStream::WriteLine}
4d1f281b 124
631f1bfe 125\func{void}{wxDataOutputStream::WriteLine}{{\param const wxString\& }{string}}
4d1f281b
GL
126
127Writes {\it string} as a line. Depending on the operating system, it adds

130\membersection{wxDataOutputStream::WriteString}
131
132\func{void}{wxDataOutputStream::WriteString}{{\param const wxString\& }{string}}
133
134Writes {\it string} to the stream. Actually, this method writes the size of
135the string before writing {\it string} itself.
