manpage(FBB::lm)(3bobcat)(_CurYrs_)(libbobcat-dev__CurVers_)
(OFoldStream manipulator)
manpagename(FBB::lm)(Manipulator setting left margins of OFoldStream objects)
manpagesynopsis()

Linking option: tt(-lbobcat)
manpagedescription()
The tt(lm) class implements a manipulator that can be inserted into
tt(OFoldStream) objects to set the stream's left margin to a requested
value.
Depending on the tab-setting of the tt(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 tt(std::flush)
or tt(std::endl) manipulator that is inserted into the stream. If a line is
still once an tt(lm) object and a tt(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 em(bad_cast) exception is thrown when the manipulator is inserted into an
tt(ostream) that is not using a tt(OFoldBuf) buffer.

-
manpagesection(CONSTRUCTOR)
itemization(
itb(lm(size_t newValue))
)
Copy and move constructors (and assignment operators) are available.
manpagesection(MEMBER FUNCTIONS)
itemization(
itb(std::ostream &modify(std::ostream &out) const)
This member is normally not directly called from
user-programs. Instead, it is called by the insertion operator when inserting
the tt(lm) manipulator.
)
manpagesection(EXAMPLE)
verb(
#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) << "\n"
"this uses a 4 character wide left margin\n" <<
lm(0) << flush << "at column 0 again\n";
}
