Detailed Description

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

Qt's base class for reference counting.

Note

This class or function is reentrant.

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.
