File Information

Library: Foundation
Package: Core
Header: Poco/Void.h

A dummy class with value-type semantics, mostly useful as a template argument.

This class is typically used together with ActiveMethod, if no argument or return value is needed.

Member Functions: operator !=, operator =, operator ==

Creates the Void.

Void(
const Void & v
);

Creates the Void from another Void.

The philosophical aspects of this operation remain undiscussed for now.

Destroys the Void.

bool operator != (
const Void & v
) const;

Will return always false due to Voids having no members.

Void & operator = (
const Void & v
);

Assigns another void.

bool operator == (
const Void & v
) const;

Will return always true due to Voids having no members.
