Detailed Description

template<class T>
class MEAL::GroupRule< T >

Abstract base class of closed, associative, binary operators.

Because the binary operation is associative, this class is implemented as a series of elements; that is, an arbitrary number of models can be added. By inheriting this class and defining the get_identity(), operate(), and partial() pure virtual methods, derived classes may define the closed, associative binary operation, such as the product or sum.
