\section{\class{wxTextInputStream}}\label{wxtextinputstream}
This class provides functions that read text datas using an input stream.
-So, you can read \it{text} floats, integers.
+So, you can read {\it text} floats, integers.
-Operator >> is overloaded and you can use this class a C++ std-iostream.
+The wxTextInputStream correctly reads text files (or streams) in DOS, Macintosh
+and Unix formats and reports a single newline char as a line ending.
+
+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 int on 32-bit architectures) so that you cannot use long. To avoid
+problems (here and elsewhere), make use of wxInt32, wxUint32 and similar types.
For example:
+
\begin{verbatim}
+ wxFileInputStream input( "mytext.txt" );
wxTextInputStream text( input );
wxUint8 i1;
float f2;
\membersection{wxTextInputStream::Read8}
-\func{unsigned char}{Read8}{\void}
+\func{wxUint8}{Read8}{\void}
Reads a single byte from the stream.
\membersection{wxTextInputStream::Read16}
-\func{unsigned short}{Read16}{\void}
+\func{wxUint16}{Read16}{\void}
Reads a 16 bit integer from the stream.
\membersection{wxTextInputStream::Read32}
-\func{unsigned long}{Read32}{\void}
+\func{wxUint32}{Read32}{\void}
Reads a 32 bit integer from the stream.
Reads a double (IEEE encoded) from the stream.
+\membersection{wxTextInputStream::ReadLine}\label{wxtextinputstreamreadline}
+
+\func{wxString}{wxTextInputStream::ReadLine}{\void}
+
+Reads a line from the input stream and returns it (without the end of line
+character).
+
\membersection{wxTextInputStream::ReadString}
\func{wxString}{wxTextInputStream::ReadString}{\void}
-Reads a line from the stream. A line is a string which ends with
-$\backslash$n or $\backslash$r$\backslash$n or $\backslash$r.
+{\bf NB:} This method is deprecated, use \helpref{ReadLine}{wxtextinputstreamreadline}
+or \helpref{ReadWord}{wxtextinputstreamreadword} instead.
+
+Same as \helpref{ReadLine}{wxtextinputstreamreadline}.
+
+\membersection{wxTextInputStream::ReadWord}\label{wxtextinputstreamreadword}
+
+\func{wxString}{wxTextInputStream::ReadWord}{\void}
+
+Reads a word (a sequence of characters until the next separator) from the
+input stream.

+
+\membersection{wxTextInputStream::SetStringSeparators}\label{wxtextinputstreamsetstringseparators}
+
+\func{void}{SetStringSeparators}{\param{const wxString\& }{sep}}
+
+Sets the characters which are used to define the word boundaries in
+\helpref{ReadWord}{wxtextinputstreamreadword}.
+
+The default separators are the space and {\tt TAB} characters.

\section{\class{wxTextOutputStream}}\label{wxtextoutputstream}
This class provides functions that write text datas using an output stream.
-So, you can write \it{text} floats, integers.
+So, you can write {\it text} floats, integers.
+
+You can also simulate the C++ cout class:
-For example:
\begin{verbatim}
- wxTextOutputStream text( output );
+ wxFFileOutputStream output( stderr );
+ wxTextOutputStream cout( output );
- output << "This is a text line\n";
- output << 1234;
- output << 1.23456;
+ cout << "This is a text line" << endl;
+ cout << 1234;
+ cout << 1.23456;
\end{verbatim}
+The wxTextOutputStream writes text files (or streams) on DOS, Macintosh
+and Unix in their native formats (concerning the line ending).
