function updateValues

cpp

virtual void updateValues(

virtual void updateValues(
    int inputIndex
) override

Computes new values of outputs based on inputs.

Parameters:

inputIndex Index of the modified input.

Reimplements: Core::Node::updateValues

Encodes the box function by updating the output values for a given inputIndex - fired by receiveSignal().

The base class method calls update callbacks registered with addUpdateCallback(). So derived methods should also call their base method if they want to inform any outside observers.
