Detailed Description

template<std::size_t _LEN_, std::size_t _ALIGN_>
class uv::aligned_storage< _LEN_, _ALIGN_ >

A wrapper around std::aligned_storage< _LEN_, _ALIGN_ >::type that simplifies initializing the provided storage space, getting from it, setting it to, and automatic destroying it from objects of any type fitting to the given size and alignment requirements.

Note

All the member functions creating a new value in the storage from their arguments use the curly brace initialization.

tag()

template<std::size_t _LEN_, std::size_t _ALIGN_>

const std::type_info* uv::aligned_storage< _LEN_, _ALIGN_ >::tag ( ) const

inlinenoexcept

The type tag of the stored value.

It's just a pointer referring to the static global constant object returned by the typeid() operator for the type of the value currently stored in this variable. nullptr is returned if the storage space is not initialized and is not holding any value.
