inlinenoexcept

Access the contained object.

Template Parameters
_ValueTypeThe type of the contained object.
Parameters

Template Parameters
_ValueTypeThe type of the contained object.
Parameters
__anyA pointer to the object to access.
Returns
The address of the contained object if __any != nullptr && __any.type() == typeid(_ValueType) , otherwise a null pointer.
