Detailed Description

A value delay operator.

This CDP operator can be used to buffer and delay output value by a configurable amount of time.

For example DelayTime=0.005 can be used to delay a value by 5 milliseconds.

Arguments

When operator is used inside a signal its default input is automatically tied to signal's InternalValue or previous operator's output. Its default output is automatically tied to next operator's input or to signal's Value. See also CDP Operator Usage In CDP Signals.

Example

Below is an example plot with Sine signal (cyan) and the same signal with Delay operator applied (orange):

Actual Processing Code of the Delay

unsigned int Delay<T>::Process()
{
  double delay=0.0;
  if (d->delayTime)
  {
    CDPVariantValue delayTime_v = d->delayTime->GetVariantValue();
    delay = delayTime_v.GetConvertedValue<double>();
    if (delay < 0.0)
    {
      GetParent()->ReportConfigurationFault(this, "Negative DelayTime");
      d->faultReported = true;
      return STATUS_SIGNAL_FAULT;
    }
  }

  d->PushCurrentValueToBuffer((T)m_input);

  m_output = d->PopDelayedValueFromBuffer((T)m_input, delay, this->GetOperatorPeriod());

  if (d->faultReported)
  {
    GetParent()->ClearConfigurationFault(this);
    d->faultReported = false;
  }
  return STATUS_OK;
}
