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.
RWTFunctor1Imp is the abstract base class for the family of functor bodies that are invoked with one argument and return no 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 or A2, to indicate at construction that it takes callee arguments. These arguments are stored in the functor body and then added to the caller argument at invocation time.
The six concrete class names are:
this
object, no callee argumentsthis
object, one callee argumentthis
object, one callee argumentthis
object, but no callee argumentsthis
object, and one callee argumentthis
object, and two 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:
S1
The type of the first functor signature argumentCallee
The class type that declares a member functionDR
The return type of the functionD1
The type of the first function signature argument; the compiler must be able to convert to this from the S1
type.A1
The type of the first client data argumentA2
The type of the second 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 rwtMakeFunctor1() convenience mechanisms. All other members must be accessed through an RWTFunctor1 handle.
