   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.

  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.
