示例1:

void
ModifyDeviceCommand::execute()
{
    Device *device = m_studio->getDevice(m_device);
    if (!device) {
        std::cerr << "ERROR: ModifyDeviceCommand::execute(): no such device as " << m_device << std::endl;
        return;
    }

    MidiDevice *midiDevice = dynamic_cast<MidiDevice *>(device);
    if (!midiDevice) {
        std::cerr << "ERROR: ModifyDeviceCommand::execute(): device " << m_device << " is not a MIDI device" << std::endl;
        return;
    }

    // Save Original Values for Undo

    // ??? Really wish we could just m_oldDevice = *(midiDevice).  See below.
    m_oldName = midiDevice->getName();
    m_oldBankList = midiDevice->getBanks();
    m_oldProgramList = midiDevice->getPrograms();
    m_oldControlList = midiDevice->getControlParameters();
    m_oldKeyMappingList = midiDevice->getKeyMappings();
    m_oldLibrarianName = midiDevice->getLibrarianName();
    m_oldLibrarianEmail = midiDevice->getLibrarianEmail();
    m_oldVariationType = midiDevice->getVariationType();
    InstrumentList instruments = midiDevice->getAllInstruments();
    for (size_t i = 0; i < instruments.size(); ++i) {
        // ??? Preserving just the programs isn't enough.  We need
        //     to preserve the rest of the Instrument as well.  However,
        //     the auto/fixed channel feature has made it impossible
        //     to safely make copies of Instrument objects.  Also, Instrument
        //     has an ID.  How should that be handled for undo?  ISTM
        //     that we either need to introduce some sort of copyForUndo()
        //     hack to each object, or develop a set of standards for coding
        //     objects that are undo-safe.  Sounds like a pretty big project.
        m_oldInstrumentPrograms.push_back(instruments[i]->getProgram());
    }

    // Make the Changes

    if (m_changeVariation)
        midiDevice->setVariationType(m_variationType);

    if (m_overwrite) {

                    instruments[i]->pickFirstProgram(
                            midiDevice->isPercussionNumber(i));
                }

        }

        if (m_changeKeyMappings) {
            midiDevice->replaceKeyMappingList(m_keyMappingList);
        }

        if (m_rename)
            midiDevice->setName(m_name);
        midiDevice->setLibrarian(m_librarianName, m_librarianEmail);
    } else {
        if (m_clearBankAndProgramList) {
            midiDevice->clearBankList();
            midiDevice->clearProgramList();

            if (m_changeBanks)
                midiDevice->mergeBankList(m_bankList);
            if (m_changePrograms)
                midiDevice->mergeProgramList(m_programList);
        }

        if (m_rename) {

    //!!! merge option?
    if (m_changeControls) {
        midiDevice->replaceControlParameters(m_controlList);
    }

    // ??? Instead of this kludge, we should be calling a Studio::hasChanged()
    //     which would then notify all observers (e.g. MIPP) who, in turn,
    //     would update themselves.
