24.2 oeistream

All of the oestream classes that provide input handling derive from this class. This class provides efficient implementations of standard input stream functions at the byte level: getbyte, get, skipbyte, peekbyte; at the data buffer level: read, skip; and at the text level: getline, skipline, gettoken. Like the standard istreams, the operator is overloaded for easy assignment of data from text streams.

This class also provides the framework but not fully functional implementations of the open and close routines. However, if a data buffer already exists in memory, an oeistream instance can be used to read from that buffer using the provided open and close routines.

char      buffer[] = "hello world!";
oeistream is;

if (is.open(buffer, 12))
{
    while (is)
    {
       int c = is.getbyte();
       oeout << c;
    }
    is.close();
}
