Map a type‐index enumerator to its corresponding C++ type.

== Synopsis

Declared in `<bslmf_invokeresult.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<int t_INDEX>
struct InvokeResult_Type;
----

== Description

Metafunction to convert a type index back to a type. For each specialization of this struct, the `type` member will be the type corresponding to `index`. For example, if `index` is `e_UCHAR`, then `InvokeResult_Type<index>::type` is `unsigned char`.
