Detailed Description

The QSharedData class is a base class for shared data objects.

QSharedData is designed to be used with QSharedDataPointer or QExplicitlySharedDataPointer to implement custom implicitly shared or explicitly shared classes. QSharedData provides thread-safe reference counting.

See QSharedDataPointer and QExplicitlySharedDataPointer for details.
