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.

Definition at line 87 of file any.


Constructor & Destructor Documentation

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.

Definition at line 129 of file any.

References empty().

Move constructor, transfer the state from __other.

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

Definition at line 146 of file any.

std::experimental::fundamentals_v1::any::any ( _ValueType &&  __value) [inline]

Construct with a copy of __value as the contained object.

Construct with a copy of __value as the contained object.
