Detailed Description

The OROperator does a bitwise OR between all the arguments and the input to produce an output.

OR has the following truth table:

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

To OR a signal value with value 0x0001, add an OROperator<unsigned short> into a Signal<unsigned short> in Configure mode. Then go into the OROperator that was added, and add an Argument<unsigned short>. Set its Value to 0x0001 (1).

How to Run the Example

To run the example from CDP Studio, open Welcome mode and find it under Examples. Next, in Configure mode right-click on the system project and select Run & Connect. See the Running the Example Project tutorial for more information.

Set the signal Value containing the OR operator to 2, and verify that the value after the operator has been applied becomes 3.

Actual Processing Code of the OROperator

unsigned int OROperator<T>::Process()
{
  T outputValue = static_cast<T>(m_input);
  for (auto arg : this->m_arguments)
    outputValue |= static_cast<T>(*arg);
  m_output = outputValue;

  return STATUS_OK;
}
