+\section{\class{wxDataInputStream}}\label{wxdatainputstream}
+
+This class provides functions that read binary data types in a
+portable way. Data can be read in either big-endian or litte-endian
+format, little-endian being the default on all architectures.
+
+If you want to read data from text files (or streams) use 
+\helpref{wxTextInputStream}{wxtextinputstream} instead.
+
+The >> operator is overloaded and you can use this class like a standard C++ iostream.
+Note, however, that the arguments are the fixed size types wxUint32, wxInt32 etc
+and on a typical 32-bit computer, none of these match to the "long" type (wxInt32
+is defined as signed int on 32-bit architectures) so that you cannot use long. To avoid
+problems (here and elsewhere), make use of the wxInt32, wxUint32, etc types.
+
+For example:
+
+\begin{verbatim}
+  wxFileInputStream input( "mytext.dat" );
+  wxDataInputStream store( input );
+  wxUint8 i1;
+  float f2;
+  wxString line;
+
+  store >> i1;       // read a 8 bit integer.
+  store >> i1 >> f2; // read a 8 bit integer followed by float.
+  store >> line;     // read a text line
+\end{verbatim}
+
+See also \helpref{wxDataOutputStream}{wxdataoutputstream}.

+\membersection{wxDataInputStream::wxDataInputStream}\label{wxdatainputstreamconstr}
+
+\func{}{wxDataInputStream}{\param{wxInputStream\&}{ stream}}
+
+Constructs a datastream object from an input stream. Only read methods will
+be available.
+
+\wxheading{Parameters}
+
+\docparam{stream}{The input stream.}
+
+\membersection{wxDataInputStream::\destruct{wxDataInputStream}}
+
+\func{}{\destruct{wxDataInputStream}}{\void}
+
+Destroys the wxDataInputStream object.
+
+\membersection{wxDataInputStream::BigEndianOrdered}
+
+\func{void}{BigEndianOrdered}{\param{bool}{ be\_order}}
+
+If {\it be\_order} is TRUE, all data will be read in big-endian
+order, such as written by programs on a big endian architecture 
+(e.g. Sparc) or written by Java-Streams (which always use 
+big-endian order).
+  
+\membersection{wxDataInputStream::Read8}
+
+\func{wxUint8}{Read8}{\void}
+
+Reads a single byte from the stream.
+
+\membersection{wxDataInputStream::Read16}
+
+\func{wxUint16}{Read16}{\void}
+
+Reads a 16 bit integer from the stream.
+
+\membersection{wxDataInputStream::Read32}
+
+\func{wxUint32}{Read32}{\void}
+
+Reads a 32 bit integer from the stream.
+
+\membersection{wxDataInputStream::ReadDouble}
+
+\func{double}{ReadDouble}{\void}
+
+Reads a double (IEEE encoded) from the stream.
+
+\membersection{wxDataInputStream::ReadString}
+
+\func{wxString}{ReadString}{\void}
+
+Reads a string from a stream. Actually, this function first reads a long integer
+specifying the length of the string (without the last null character) and then
+reads the string.
