Record Class StrategySelected

java.lang.Object
java.lang.Record
com.graphhopper.jsprit.core.algorithm.listener.events.StrategySelected
Record Components:
iteration - The iteration number
timestamp - When the strategy was selected
strategyId - The ID/name of the selected strategy
All Implemented Interfaces:
AlgorithmEvent
public record StrategySelected(int iteration, long timestamp, String strategyId) extends Record implements AlgorithmEvent
Emitted when a search strategy is selected for the current iteration, before the strategy runs (ruin/recreate).

This event allows listeners to know which strategy will be used for the upcoming ruin/recreate operations.

  • Constructor Details

    • StrategySelected

      public StrategySelected(int iteration, long timestamp, String strategyId)
      Creates an instance of a StrategySelected record class.
      Parameters:
      iteration - the value for the iteration record component
      timestamp - the value for the timestamp record component
      strategyId - the value for the strategyId record component

  • 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

    • strategyId

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