Detailed Description

template<class TYPE>
class bslalg::NothrowMovableWrapper< TYPE >

An object of this type wraps a value of the specified TYPE, and provides no other functionality other than returning the wrapped object. The move constructor is guaranteed not to throw, even if the move constructor for TYPE has no such guarantee. The user is thus asserting that the move constructor for the wrapped object will not throw, even if it is allowed to. Constraints: this class can be instantiated on object types only, i.e., not references, arrays, or function types (though function pointers are OK).
