\section{\class{wxDataInputStream}}\label{wxdatainputstream} This class provides functions that read data types in a portable way. So, a file written by an Intel processor can be read by a Sparc or anything else. \wxheading{Derived from} \helpref{wxFilterInputStream}{wxfilterinputstream}\\ \helpref{wxInputStream}{wxinputstream}\\ \helpref{wxStreamBase}{wxstreambase} \wxheading{Include files} \latexignore{\rtfignore{\wxheading{Members}}} \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::Read8} \func{unsigned char}{Read8}{\void} Reads a single byte from the stream. \membersection{wxDataInputStream::Read16} \func{unsigned short}{Read16}{\void} Reads a 16 bit integer from the stream. \membersection{wxDataInputStream::Read32} \func{unsigned long}{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::ReadLine} \func{wxString}{wxDataInputStream::ReadLine}{\void} Reads a line from the stream. A line is a string which ends with \\n or \\r\\n. \membersection{wxDataInputStream::ReadString} \func{wxString}{wxDataInputStream::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. \section{\class{wxDataOutputStream}}\label{wxdataoutputstream} This class provides functions that write data types in a portable way. So, a file written by an Intel processor can be read by a Sparc or anything else. \latexignore{\rtfignore{\wxheading{Members}}} \membersection{wxDataOutputStream::wxDataOutputStream}\label{wxdataoutputstreamconstr} \func{}{wxDataInputStream}{\param{wxOutputStream\&}{ stream}} Constructs a datastream object from an output stream. Only read methods will be available. \wxheading{Parameters} \docparam{stream}{The output stream.} \membersection{wxDataOutputStream::\destruct{wxDataOutputStream}} \func{}{\destruct{wxDataOutputStream}}{\void} Destroys the wxDataOutputStream object. \membersection{wxDataOutputStream::Write8} \func{void}{wxDataOutputStream::Write8}{{\param unsigned char }{i8}} Writes the single byte {\it i8} to the stream. \membersection{wxDataOutputStream::Write16} \func{void}{wxDataOutputStream::Write16}{{\param unsigned short }{i16}} Writes the 16 bit integer {\it i16} to the stream. \membersection{wxDataOutputStream::Write32} \func{void}{wxDataOutputStream::Write32}{{\param unsigned long }{i32}} Writes the 32 bit integer {\it i32} to the stream. \membersection{wxDataOutputStream::WriteDouble} \func{void}{wxDataOutputStream::WriteDouble}{{\param double }{f}} Writes the double {\it f} to the stream using the IEEE format. \membersection{wxDataOutputStream::WriteLine} \func{void}{wxDataOutputStream::WriteLine}{{\param const wxString\& }{string}} Writes {\it string} as a line. Depending on the operating system, it adds $\backslash$n or $\backslash$r$\backslash$n. \membersection{wxDataOutputStream::WriteString} \func{void}{wxDataOutputStream::WriteString}{{\param const wxString\& }{string}} Writes {\it string} to the stream. Actually, this method writes the size of the string before writing {\it string} itself.
