== Base Classes

[cols="1,4"]
|===
| Name| Description
| `xref:bsl/decay.adoc[bsl::decay<t_TYPE>]`
| Metafunction to return the variant of the specified parameter `t_TYPE` used for pass‐by‐reference, e.g., by applying array‐to‐pointer and function‐to‐pointer conversion.

== Type Aliases

[cols="1,4"]

| Name| Description
| xref:bsl/decay/type.adoc[`type`] 
| This `typedef` is an alias to the decayed form of `t_TYPE`.

== Derived Classes

[cols="1,4"]
|===
| Name| Description
| xref:BloombergLP/bslmf/MovableRefUtil/Decay.adoc[`Decay`] 
| This `struct` template provides a metafunction that defines a nested `type` typedef that applies lvalue‐to‐rvalue, array‐to‐pointer, and function‐to‐pointer conversions that occur when an lvalue of type `t_TYPE` is used as an rvalue, and also removes `const`, `volatile`, and reference qualifiers from class types in order to model by‐value argument passing. For the purpose of this type trait, `MovableRef<T>` is considered a (movable) reference‐qualified `T`.
