Detailed Description

template<typename Fun>
template<typename Expr, typename State, typename Data>
struct boost::proto::call< Fun()>::impl< Expr, State, Data >

Either call the PolymorphicFunctionObject Fun with 0 arguments; or invoke the PrimitiveTransform Fun with 3 arguments: the current expression, state, and data.

If Fun is a nullary PolymorphicFunctionObject, return Fun()(). Otherwise, return Fun()(e, s, d).

Parameters

e	The current expression
s	The current state
d	An arbitrary data If Fun is a nullary PolymorphicFunctionObject, type is a typedef for boost::result_of<Fun()>::type. Otherwise, it is a typedef for boost::result_of<Fun(Expr, State, Data)>::type.
