Class CheckpointState

java.lang.Object

ptolemy.backtrack.CheckpointState

public class CheckpointState
extends java.lang.Object

The current state of a checkpoint object. A checkpoint object stores its complete state in its CheckpointState object. Different checkpoint objects may share the same state, and hence they represent the same checkpoint entity.

When two checkpoint objects are merged, they exchange their states and compute the union of the two.
