[1] Class MBool

[TOC]

1 Overview

The class MBool represents a truth value over one or more time
intervals. Such a pair (value,interval) is called a *unit* (see class ~UBool~)

#include "fmr_MBool.h"

using namespace fmr;

/*
2 ~addUnit~

Adds a new unit to this ~MBool~, which represents the
truth value ~val~ over the interval ~iv~.

*/
void MBool::addUnit (Interval iv, bool val) {
    units.push_back(UBool(iv, val));
    std::sort(units.begin(), units.end());

    std::vector<UBool>::iterator ui = units.begin();
    while (ui != units.end()) {
        std::vector<UBool>::iterator ui2 = ui + 1;
        if (ui2 == units.end())
            break;
        if ((ui->iv.end == ui2->iv.start) &&
            (ui->iv.rc || ui2->iv.lc) &&

        } else {
            ui++;
        }
    }

/*
3 ~ToString~

Returns a string representation of this MBool.

*/

/*
4 ~toRList~

Returns an RList representation of this MBool.

*/
