示例1: setOnHand
DECLARE_EXPORT void Buffer::setOnHand(double f)
{
// The dummy operation to model the inventory may need to be created
Operation *o = Operation::find(INVENTORY_OPERATION);
Flow *fl;
if (!o)
{
// Create a fixed time operation with zero leadtime, hidden from the xml
// output, hidden for the solver, and without problem detection.
o = new OperationFixedTime();
o->setName(INVENTORY_OPERATION);
o->setHidden(true);
o->setDetectProblems(false);
fl = new FlowEnd(o, this, 1);
}
else
// Find the flow of this operation
fl = const_cast<Flow*>(&*(o->getFlows().begin()));
// Check valid pointers
if (!fl || !o)
throw LogicException("Failed creating inventory operation for '"
+ getName() + "'");
// Make sure the sign of the flow is correct: +1 or -1.
fl->setQuantity(f>=0.0 ? 1.0 : -1.0);
// Create a dummy operationplan on the inventory operation
OperationPlan::iterator i(o);
