Detailed Description

template<class t_TYPE>
struct bslmf::MovableRefUtil::Decay< t_TYPE >

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.

Formally, let U be MovableRefUtil::RemoveReference<t_TYPE>type. If bsl::is_array<U>value is true, the member typedef type is bsl::remove_extent<U>type *. If bsl::is_function<U>value is true, the member typedef type is bsl::add_pointer<U>type. Otherwise, the member typedef type is bsl::remove_cv<U>type.
