C++ (Cpp) DataItem::getComponent Examples

Example #1

File: data_item.cpp Project: CubeSpawn-Research/MTConnectToolbox

// Sort by: Device, Component, Category, DataItem
bool DataItem::operator<(DataItem &aOther) 
{
  Device *dev = mComponent->getDevice();
  if (dev->getId() < aOther.getComponent()->getDevice()->getId())
    return true;
  else if (dev->getId() > aOther.getComponent()->getDevice()->getId())

  else if (mComponent->getId() < aOther.getComponent()->getId())
    return true;
  else if (mComponent->getId() > aOther.getComponent()->getId())

  else if (mCategory < aOther.mCategory)
    return true;
  else if (mCategory == aOther.mCategory)
    return mId < aOther.mId;
