Detailed Description

The DeltaTimeOperator measures the time between input signal changes.

The DeltaTimeOperator detects changes in the input (In) and on each change sets output argument (DeltaTime) to the delta time (in seconds) since the previous value change.

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.

Actual Processing Code of the DeltaTimeOperator

unsigned int DeltaTimeOperator<T>::Process()
{
  if (!m_deltaTime)
    return STATUS_ERROR;

  if ((T)m_input != m_lastValue)
  {
    *m_deltaTime = CDPTime::GetGlobalTime() - m_lastTime;
    m_lastTime = CDPTime::GetGlobalTime();
  }

  m_output = m_input;
  m_lastValue = (T)m_input;

  return STATUS_OK;
}
