Record Class InsertionEvaluated

java.lang.Object
java.lang.Record
com.graphhopper.jsprit.core.algorithm.listener.events.InsertionEvaluated
Record Components:
iteration - The iteration number
timestamp - When the event occurred
job - The job being inserted
routeId - The route being evaluated (vehicle ID)
position - The insertion position in the route
cost - The total insertion cost (Double.MAX_VALUE if infeasible)
breakdown - The cost breakdown (null if infeasible)
feasible - Whether the insertion is feasible
failedConstraints - Names of constraints that failed (empty if feasible)
chosen - Whether this insertion was chosen as the best
All Implemented Interfaces:
AlgorithmEvent
public record InsertionEvaluated(int iteration, long timestamp, Job job, String routeId, int position, double cost, InsertionCostBreakdown breakdown, boolean feasible, List<String> failedConstraints, boolean chosen) extends Record implements AlgorithmEvent
Event emitted when an insertion is evaluated for a job.

This provides full transparency into the insertion decision, including cost breakdown and why certain routes were rejected.

  • Method Details

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • iteration

      public int iteration()
      Returns the value of the iteration record component.
      Specified by:
      iteration in interface AlgorithmEvent
      Returns:
      the value of the iteration record component

    • timestamp

      public long timestamp()
      Returns the value of the timestamp record component.
      Specified by:
      timestamp in interface AlgorithmEvent
      Returns:
      the value of the timestamp record component

    • job

      public Job job()
      Returns the value of the job record component.
      Returns:
      the value of the job record component

    • routeId

      public String routeId()
      Returns the value of the routeId record component.
      Returns:
      the value of the routeId record component

    • position

      public int position()
      Returns the value of the position record component.
      Returns:
      the value of the position record component

    • cost

      public double cost()
      Returns the value of the cost record component.
      Returns:
      the value of the cost record component

    • breakdown

      public InsertionCostBreakdown breakdown()
      Returns the value of the breakdown record component.
      Returns:
      the value of the breakdown record component

    • feasible
