Data - object containing undo information for storage in a command

#include <Unidraw/Command/data.h>

Data is an abstract base class for objects that components store in commands they (un)interpret. Components use Data subclasses to store whatever information they need to uninterpret the command.

The constructor is protected to prevent instantiation.
