Examples of ptolemy.backtrack.Checkpoint

ptolemy.backtrack.Checkpoint
The class of checkpoint objects. A checkpoint object represents the smallest entity on which checkpoints are created and managed. It monitors one or more objects. When the {@link #rollback(long,boolean)} function is called, allthe monitored objects are rolled back to their previous states, defined by a timestamp. @author Thomas Feng @version $Id: Checkpoint.java,v 1.13.4.1 2008/03/25 22:11:40 cxh Exp $ @since Ptolemy II 5.1 @Pt.ProposedRating Red (tfeng) @Pt.AcceptedRating Red (tfeng)
