C++ (Cpp) recalculateAverageRates Examples

Example #1

File: port.cpp Project: dancollins/ostinato

bool Port::deleteStreamAt(int index)
{
    if (index >= mStreams.size())
        return false;

    delete mStreams.takeAt(index);
    updateStreamOrdinalsFromIndex();
    recalculateAverageRates();

    return true;
}

Example #2

File: port.cpp Project: anju61188/ostinato

void Port::updatePortConfig(OstProto::Port *port)
{
    bool recalc = false;

    if (port->has_transmit_mode() 
            && port->transmit_mode() != d.transmit_mode())
        recalc = true;

    d.MergeFrom(*port);

    if (recalc)
        recalculateAverageRates();
}

Example #3

File: port.cpp Project: dancollins/ostinato

bool Port::newStreamAt(int index, OstProto::Stream const *stream)
{
    Stream    *s = new Stream;

    if (index > mStreams.size())
