template<class PROTOTYPE>
class function
    : public BloombergLP::bslstl::Function_Variadic<PROTOTYPE>

Name	Description
`BloombergLP::bslstl::Function_Variadic<PROTOTYPE>`	This component-private class template contains the physical representation and provides the variadic interfaces for `bsl::function`.

Name	Description
`allocator_type`	Alias for the allocator type of the function representation.

Name	Description
`function` [constructor]	Constructors
`operator=`	Assignment operators
`allocator`	Return `get_allocator().mechanism()`. Note that this function exists for BDE compatibility and is not part of the C++ Standard Library.
`get_allocator`	Return (a copy of) the allocator used to supply memory for this `function`.
`isInplace`	Return whether this object's target uses in-place storage.
`swap`	Exchange the targets held by this `function` and the specified `other`.
`target`	`target` overloads
`target_type`	Return `typeid(void)` if this object is empty; otherwise `typeid(FUNC)` where `FUNC` is the type of the target object.
`operator BloombergLP::bdef_Function<PROTOTYPE*>&`	Convert `*this` to a mutable `bdef_Function` reference by downcasting.
`operator BloombergLP::bslmf::NestedTraitDeclaration<function, UsesAllocatorArgT>`	Nested trait declaration for `bslmf::UsesAllocatorArgT`.
`operator BloombergLP::bslmf::NestedTraitDeclaration<function, UsesBslmaAllocator>`	Nested trait declaration for `bslma::UsesBslmaAllocator`.
`operator BloombergLP::bslmf::NestedTraitDeclaration<function, is_nothrow_move_constructible>`	Nested trait declaration for `is_nothrow_move_constructible`.
`operator bool`	Return whether this `function` currently holds a target.
`operator BloombergLP::bdef_Function<PROTOTYPE*> const&`	Convert `*this` to a const `bdef_Function` reference by downcasting.

Name	Description
`operator()`	Invoke the target with the call arguments, or throw if empty.

Name	Description
`function<PROTOTYPE>`	Deduce the template parameter `PROTOTYPE` from the signature of the `operator()` of the functor supplied to the constructor of `function`.
`function<PROTOTYPE>`	Deduce the template parameter `PROTOTYPE` from the signature of the `operator()` of the functor supplied to the constructor of `function`.
`function<RET(ARGS...)>`	Deduce the template parameter `PROTOTYPE` from the signature of the function supplied to the constructor of `function`.
`function<RET(ARGS...)>`	Deduce the template parameter `PROTOTYPE` from the signature of the function supplied to the constructor of `function`.

Name	Description
`operator!=`	Return `true` if the specified `function` is not empty.
`operator==`	Return `true` if the specified `function` is empty.
`swap`	Exchange the targets held by the specified `a` and `b` functions.
