Detailed Description

template<class Target, class R1, class R2, class RelationFunctor>
class Relation2< Target, R1, R2, RelationFunctor >

Relation2 is a template used to construct relations that depend on two additional fields (e.g., a = b + c).

The Target must be a Field. The RelationFunctor must be Default Constructable and Assignable. In addition, it must provide the constructor

template<class L, class R1, class R2> RelationFunctor(const L &, const R1 &, const R2 &, const RelationFunctor &)

and the member function

template<class L, class R1, class R2> void operator()(const L &const R1 &, const R2 &) const

where L, R1, and R2 are Fields. The constructor should use the arguments to initialize itself and the function should apply the relation.
