Detailed Description

A type-safe container of any type.

An any object's state is either empty or it stores a contained object of CopyConstructible type.

Constructor & Destructor Documentation

std::experimental::fundamentals_v1::any::any ( )
inlinenoexcept

Default constructor, creates an empty object.

Definition at line 126 of file any.

Referenced by operator=().

std::experimental::fundamentals_v1::any::any ( const any __other)
inline

Copy constructor, copies the state of __other.

std::experimental::fundamentals_v1::any::any ( any &&  __other)
inlinenoexcept

Move constructor, transfer the state from __other.

Postcondition
__other.empty() (this postcondition is a GNU extension)
