A function object, or a functor, encapsulates a call to an associated global or member function. When a functor is invoked, it calls the associated function.
Class RWTFunctorR0Imp is the abstract base class for the family of functor bodies that take no caller arguments at invocation time and return a value.
Each derived class name appends either a G (for global) or an M (for member), to indicate whether it is invoked upon an object. Static member functions use the G version since there is no object associated with the call.
The class name may also append A1, A2, or A3, to indicate that it takes callee arguments at construction time. These arguments are stored and added to the caller argument at invocation time.
The eight concrete class names are:
this
object, no callee argumentsthis
object, one callee argumentthis
object, two callee argumentsthis
object, three callee argumentsthis
object, no callee argumentsthis
object, and one callee argumentthis
object, and two callee argumentsthis
object, and three callee argumentsThese concrete classes are templatized on the signature of the function that is encapsulated, as well as on the signature of the functor invocation.
The template parameters describe the invocation signature of the functor and the function call it encapsulates. These parameters are:
SR
The return type of the functorCallee
The class type that declares a member functionDR
The return type of the functionA1
The type of the first client data argumentA2
The type of the second client data argumentA3
The type of the third client data argumentThe make()
function is the only member of these functor classes that is intended to be accessed directly; it is often called through one of the rwtMakeFunctorR0() convenience mechanisms. All other members must be accessed through an RWTFunctorR0 handle.
