LineWrapper()

option::PrintUsageImplementation::LineWrapper::LineWrapper ( int  x1, int  x2  )

inline

Constructs a LineWrapper that wraps its output to fit into screen columns x1 (incl.) to x2 (excl.).

x1 gives the indentation LineWrapper uses if it needs to indent.

Member Function Documentation

process()

void option::PrintUsageImplementation::LineWrapper::process ( IStringWriter &  write, const char *  data, int  len  )

inline

Process, wrap and output the next piece of data.

process() will output at least one line of output. This is not necessarily the data passed in. It may be data queued from a prior call to process(). If the internal buffer is full, more than 1 line will be output.

process() assumes that the a proper amount of indentation has already been output. It won't write any further indentation before the 1st line. If more than 1 line is written due to buffer constraints, the lines following the first will be indented by this method, though.

No \n is written by this method after the last line that is written.

Parameters

write	where to write the data.
data	the new chunk of data to write.
len	the length of the chunk of data to write.
