## Class Job

- java.lang.Object
- - net.sf.cpsolver.ifs.model.Constraint<Operation,Location>
  - - net.sf.cpsolver.ifs.example.jobshop.Job

- All Implemented Interfaces:
    Comparable<Constraint<Operation,Location>>

      public class Job
      extends Constraint<Operation,Location>

  Job constraint.
  Each job contians a given set of operations (variables). A job constraint is satisfied, if all operations of the job do not overlap in time and are processed in the given order.
