% ---------------------------------------------------------------------------- % wxTextInputStream % ---------------------------------------------------------------------------- \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. 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; wxString line; text >> i1; // read a 8 bit integer. text >> i1 >> f2; // read a 8 bit integer followed by float. text >> line; // read a text line \end{verbatim} \wxheading{Include files} \latexignore{\rtfignore{\wxheading{Members}}} \membersection{wxTextInputStream::wxTextInputStream}\label{wxtextinputstreamconstr} \func{}{wxTextInputStream}{\param{wxInputStream\&}{ stream}} Constructs a text stream object from an input stream. Only read methods will be available. \wxheading{Parameters} \docparam{stream}{The input stream.} \membersection{wxTextInputStream::\destruct{wxTextInputStream}} \func{}{\destruct{wxTextInputStream}}{\void} Destroys the wxTextInputStream object. \membersection{wxTextInputStream::Read8} \func{wxUint8}{Read8}{\void} Reads a single byte from the stream. \membersection{wxTextInputStream::Read16} \func{wxUint16}{Read16}{\void} Reads a 16 bit integer from the stream. \membersection{wxTextInputStream::Read32} \func{wxUint32}{Read32}{\void} Reads a 32 bit integer from the stream. \membersection{wxTextInputStream::ReadDouble} \func{double}{ReadDouble}{\void} 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} {\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. \wxheading{See also} \helpref{SetStringSeparators}{wxtextinputstreamsetstringseparators} \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. % ---------------------------------------------------------------------------- % wxTextOutputStream % ---------------------------------------------------------------------------- \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. You can also simulate the C++ cout class: \begin{verbatim} wxFFileOutputStream output( stderr ); wxTextOutputStream cout( output ); 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). \latexignore{\rtfignore{\wxheading{Members}}} \membersection{wxTextOutputStream::wxTextOutputStream}\label{wxtextoutputstreamconstr} \func{}{wxTextOutputStream}{\param{wxOutputStream\&}{ stream}, \param{wxEOL}{ mode = wxEOL\_NATIVE}} Constructs a text stream object from an output stream. Only write methods will be available. \wxheading{Parameters} \docparam{stream}{The output stream.} \docparam{mode}{The end-of-line mode. One of {\bf wxEOL\_NATIVE}, {\bf wxEOL\_DOS}, {\bf wxEOL\_MAC} and {\bf wxEOL\_UNIX}.} \membersection{wxTextOutputStream::\destruct{wxTextOutputStream}} \func{}{\destruct{wxTextOutputStream}}{\void} Destroys the wxTextOutputStream object. \membersection{wxTextOutputStream::GetMode} \func{wxEOL}{wxTextOutputStream::GetMode}{\void} Returns the end-of-line mode. One of {\bf wxEOL\_DOS}, {\bf wxEOL\_MAC} and {\bf wxEOL\_UNIX}. \membersection{wxTextOutputStream::SetMode} \func{void}{wxTextOutputStream::SetMode}{{\param wxEOL}{ mode = wxEOL\_NATIVE}} Set the end-of-line mode. One of {\bf wxEOL\_NATIVE}, {\bf wxEOL\_DOS}, {\bf wxEOL\_MAC} and {\bf wxEOL\_UNIX}. \membersection{wxTextOutputStream::Write8} \func{void}{wxTextOutputStream::Write8}{{\param wxUint8 }{i8}} Writes the single byte {\it i8} to the stream. \membersection{wxTextOutputStream::Write16} \func{void}{wxTextOutputStream::Write16}{{\param wxUint16 }{i16}} Writes the 16 bit integer {\it i16} to the stream. \membersection{wxTextOutputStream::Write32} \func{void}{wxTextOutputStream::Write32}{{\param wxUint32 }{i32}} Writes the 32 bit integer {\it i32} to the stream. \membersection{wxTextOutputStream::WriteDouble} \func{virtual void}{wxTextOutputStream::WriteDouble}{{\param double }{f}} Writes the double {\it f} to the stream using the IEEE format. \membersection{wxTextOutputStream::WriteString} \func{virtual void}{wxTextOutputStream::WriteString}{{\param const wxString\& }{string}} Writes {\it string} as a line. Depending on the end-of-line mode the end of line ('$\backslash$n') characters in the string are converted to the correct line ending terminator.
