NAME

FBB::mlm - Manipulator modifying left margins of OFoldStream objects

SYNOPSIS

#include <bobcat/ofoldstream> or
#include <bobcat/ofoldstreambuf>
Linking option: -lbobcat

DESCRIPTION

The mlm class implements a manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the request then left margin 0 will silently be used.

Depending on the tab-setting of the OFoldStream the inserted value represents the number of blank space characters or the number of tab-characters that will be added to the left margin.

The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream. If a line is still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at the next word inserted into that line (cf., the example section below)

A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.

         out << "hello world (left margin is 0)" << mlm(4) << "\n"
                "this uses a 4 character wide left margin\n" << 
                 mlm(-10) << flush <<
                 "left margin -6 changed to 0, active on this line\n";
         return 0;
     }
