// The abstract base class ArrayFunctorBase is defined for functors to
// be used in functions like slidingXXX.
// Virtual functions instead of templated functions are used to avoid
// code bloat when used in functions like partialArrayMath. Because a
// reduction operation usually takes much more time than the call, using
// virtual functions hardly imposes a performance penalty.
