Detailed Description
template<class RET, class... ARGS>
class bslstl::Function_Variadic< RET(ARGS...)>
This component-private class template contains the physical representation and provides the variadic interfaces for bsl::function (see class and component documentation for bsl::function). bsl::function publicly inherits from an instantiation of this template. This implementation class exists to 1) minimize the amount of variadic template expansion required in C++03 using the sim_cpp11_features.pl utility and 2) work around issues with the Sun CC compiler, which has trouble with argument type deduction when a template argument has a partial specialization (as Function_Variadic does). bsl::function does not have a partial specialization and delegates to the Function_Variadic base class only those parts of the interface and implementation that depend on decomposing the function prototype into a return type and variadic list of argument types.

Constructor & Destructor Documentation
| bslstl::Function_Variadic< RET(ARGS...)>::Function_Variadic | ( | const allocator_type & | allocator | ) |
Create an empty object. Use the specified allocator (e.g., the address of a bslma::Allocator) to supply memory.
| bslstl::Function_Variadic< RET(ARGS...)>::~Function_Variadic | ( | ) |
// Destroy this object and its target object.
Member Function Documentation
| RET bslstl::Function_Variadic< RET(ARGS...)>::operator() | ( | ARGS... | args | ) | const |
If this object is empty, throw bsl::bad_function_call; otherwise invoke the target object with the specified args... and return the result (after conversion to RET). Note that, even though it is declared const, this call operator can mutate the target object and is thus considered a manipulator rather than an accessor.
