Detailed Description

This struct provides a collection of utility functions operating on objects of type MovableRef<t_TYPE>. The primary use of these utilities to create a consistent notation for using the C++03 MovableRef<t_TYPE> objects and the C++11 t_TYPE&& r-value references.

inlinestatic

Return a const-qualified reference to the specified lvalue. This function is selected by overload resolution if the move constructor for t_TYPE might throw an exception. Constructing a t_TYPE object from the result will result in the copy constructor being invoked rather than the (unsafe) move constructor.

move_if_noexcept() [2/2]

template<class t_TYPE >

static bsl::enable_if<!bsl::is_copy_constructible< t_TYPE >::value||bsl::is_nothrow_move_constructible< t_TYPE >::value, MovableRef< t_TYPE > >::type bslmf::MovableRefUtil::move_if_noexcept ( t_TYPE &  lvalue )

inlinestatic

Return a movable reference to the specified lvalue. This function is selected by overload resolution if the move constructor for t_TYPE is nothrow-move-constructible. Constructing a t_TYPE object from the result will result in the (safe) move constructor being invoked. Note that that the bsl::is_nothrow_move_constructible trait can be customized in C++03 mode to indicate that a type is nothrow-move-constructible.
