Detailed Description

The InterlockOperator overrides output to Set value if comparisson evaluates to true instead of input value.

An InterlockOperator sets the output value depending on the 'Comparator' and CompareLeft/CompareRight values. It sets output value to Set value if CompareLeft and CompareRight comparisson expression is true, otherwise it sets output value to input value.

Properties and 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 InterlockOperator

unsigned int InterlockOperator<T>::Process()
{
  if (!d->setValue || !d->compareLeft || !d->compareRight)
    return STATUS_ERROR;

  if(!isForced())
  {
    this->m_output = static_cast<T>(this->m_input);
    return STATUS_OK;
  }
  else
  {
    this->m_output = static_cast<T>(*(d->setValue));
    return STATUS_VALUE_FORCED;
  }
}
