Detailed Description

The PriorityEncoder

PriorityEncoder is an operator that encodes the highest valued input's index as an output Index value. It implements the Priority encoder algorithm but also extends this for values. https://en.wikipedia.org/wiki/Priority_encoder

Arguments

NameDescription
IndexIndex of the first occurrence of input argument with the highest value in Priority model and lowest value in InversePriority mode. When IgnoreZeroValues is set the encoder will not consider 0 at inputs as a value. The Index value for the first input argument is '0'. When none of the inputs are high, the Index value defaults to '0'.

Actual Processing Code of the PriorityEncoder

unsigned int PriorityEncoder<T>::Process()
{
  auto selected = 0u;
  bool priority = m_mode == "Priority";
  T indexedValue = priority?std::numeric_limits<T>::lowest():std::numeric_limits<T>::max();
  for (auto i=0u; i < m_arguments.size(); i++)
    if ((!m_ignoreZeroValues || *m_arguments[i]!=static_cast<T>(0)) && m_arguments[i] != m_index)
    {
      if (priority && *m_arguments[i] > indexedValue)
      {
        selected = i - 1;
        indexedValue = static_cast<T>(*m_arguments[i]);
      }
      else if (!priority && *m_arguments[i] < indexedValue) {
        selected = i - 1;
        indexedValue = static_cast<T>(*m_arguments[i]);
      }
    }
  *m_index = selected;
  return STATUS_OK;
}
