Detailed Description

The ANDOperator does a bitwise AND between all the arguments and the input to produce an output.

AND has the following truth table:

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

To AND a signal value with value 0xfffe, add an ANDOperator<unsigned short> to an unsigned short Signal in Configure mode. Then go into the ANDOperator and add an Argument<unsigned short>. Set its Value to 0xfffe (65534).

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 AND operator to 65535, and verify that the value after the operator has been applied becomes 65534.

Actual Processing Code of the ANDOperator

unsigned int ANDOperator<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;
}
