Specializations

Name	Description
`InvokeResult_MemObjPtrImpDispatch<bslmf::VoidType<decltype((InvokeResult_ImpUtils::myDeclval<t_ARGTYPE>()). InvokeResult_ImpUtils::myDeclval<t_FN>())>::type, false, false, t_FN, t_ARGTYPE>`	Implementation of `invoke_result<t_FN, t_ARGTYPE>`. This specialization is instantiated in C++11 and later when `t_FN` is a pointer-to-member-object type, `t_ARGTYPE` is neither a class type that derives from the class type of `t_FN` nor a specialization of `bsl::reference_wrapper`, and the `INVOKE(fn, arg)` expression is well-formed given `fn` is an object of the specified `t_FN` type and `arg` is an object of the specified `t_ARGTYPE` type. The `INVOKE(fn, arg)` expression in this case is `(arg).fn`.
`InvokeResult_MemObjPtrImpDispatch<bslmf::VoidType<decltype(InvokeResult_ImpUtils::myDeclval<t_ARGTYPE>().* InvokeResult_ImpUtils::myDeclval<t_FN>())>::type, true, false, t_FN, t_ARGTYPE>`	Implementation of `invoke_result<t_FN, t_ARGTYPE>`. This specialization is instantiated in C++11 and later when `t_FN` is a pointer-to-member-object type, `t_ARGTYPE` is a class type that derives from the class type of `t_FN`, and the `INVOKE(fn, arg)` expression is well-formed given `fn` is an object of the specified `t_FN` type and `arg` is an object of the specified `t_ARGTYPE` type. The `INVOKE(fn, arg)` expression in this case is `arg1.*fn`.
`InvokeResult_MemObjPtrImpDispatch<bslmf::VoidType<decltype(InvokeResult_ImpUtils::myDeclval<t_ARGTYPE>().get().* InvokeResult_ImpUtils::myDeclval<t_FN>())>::type, false, true, t_FN, t_ARGTYPE>`	Implementation of `invoke_result<t_FN, t_ARGTYPE>`. This specialization is instantiated in C++11 and later when `t_FN` is a pointer-to-member-object type, `t_ARGTYPE` is a specialization of `bsl::reference_wrapper`, and the `INVOKE(fn, arg)` expression is well-formed given `fn` is an object of the specified `t_FN` type and `arg` is an object of the specified `t_ARGTYPE` type. The `INVOKE(fn, arg)` expression in this case is `arg.get().*fn`.

Derived Classes

Name	Description
`InvokeResult_MemObjPtrImp<t_FN, t_ARGTYPE>`	Implementation of `invoke_result<t_FN, t_ARGTYPES...>`. This specialization is instantiated in C++11 and later when `t_FN` is a pointer-to-member-object type and the `t_ARGTYPES...` pack contains exactly 1 type.
