FBB::lm(3bobcat)                                              OFoldStream manipulator                                             FBB::lm(3bobcat)

NAME
FBB::lm - Manipulator setting left margins of OFoldStream objects SYNOPSIS
#include <bobcat/ofoldstream> or #include <bobcat/ofoldstreambuf> Linking option: -lbobcat DESCRIPTION
The lm class implements a manipulator that can be inserted into OFoldStream objects to set the stream's left margin to a requested value. 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 used for 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 once an lm 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. NAMESPACE
FBB All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB. INHERITS FROM
- CONSTRUCTOR
o lm(size_t newValue): The standard copy constructor is available. MEMBER FUNCTIONS
There are no public or protected member functions in this class. EXAMPLE
#include <iostream> #include <bobcat/ofoldstream> using namespace std; using namespace FBB; int main() { OFoldStream out(cout, 0, 80); out << "hello world (left margin is 0)" << lm(4) << " " "this uses a 4 character wide left margin " << lm(0) << flush << "at column 0 again "; return 0; } FILES
