Interface Constraint

All Known Implementing Classes:

public interface Constraint

Determines the operating parameters of a task. Each constraint has the oportunity to react to each user input event. When a task is scheduled for execution, the constraints are located and each has its value set. Then the constraints process all user events until the task is completed (usually because one of the constraints calls setSuccessful() in TaskProperties).
All Constraint toString() methods should return just the fully qualifed classname of the constraint.
