      Specified by:
      atLeastNumOffsprings in interface Elitism
      Returns:
      how many offsprings that elitism will always select

    • survivorSelectionPolicy

      public SelectionPolicy survivorSelectionPolicy()
      Returns the policy used to select survivors for the next generation.
      Specified by:
      survivorSelectionPolicy in interface Elitism
      Returns:
      the policy used to select survivors for the next generation

    • atLeastNumSurvivors

      public int atLeastNumSurvivors()
      Returns how many survivors that elitism will always select.
      Specified by:
      atLeastNumSurvivors in interface Elitism
      Returns:

    • offspringRatio

      public double offspringRatio()
      Returns how many children will be generated at each iteration. Value must be between 0 and 1 (inclusive)

    • withOffspringSelectionPolicy

      public final ImmutableElitism withOffspringSelectionPolicy(SelectionPolicy value)
      Copy the current immutable object by setting a value for the offspringSelectionPolicy attribute. A shallow reference equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for offspringSelectionPolicy
      Returns:
      A modified copy or the this object

    • withAtLeastNumOffsprings

      public final ImmutableElitism withAtLeastNumOffsprings(int value)
      Copy the current immutable object by setting a value for the atLeastNumOffsprings attribute. A value equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for atLeastNumOffsprings
      Returns:
      A modified copy or the this object

    • withSurvivorSelectionPolicy

      public final ImmutableElitism withSurvivorSelectionPolicy(SelectionPolicy value)
      Copy the current immutable object by setting a value for the survivorSelectionPolicy attribute. A shallow reference equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for survivorSelectionPolicy
      Returns:
      A modified copy or the this object

    • withAtLeastNumSurvivors

      public final ImmutableElitism withAtLeastNumSurvivors(int value)
      Copy the current immutable object by setting a value for the atLeastNumSurvivors attribute. A value equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for atLeastNumSurvivors
      Returns:
      A modified copy or the this object

    • withOffspringRatio

      public final ImmutableElitism withOffspringRatio(double value)
      Copy the current immutable object by setting a value for the offspringRatio attribute. A value strict bits equality used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for offspringRatio
      Returns:
      A modified copy or the this object

    • equals

      public boolean equals(Object another)
      This instance is equal to all instances of ImmutableElitism that have equal attribute values.
      Overrides:
      equals in class Object
      Returns:
      true if this is equal to another instance

    • equalsByValue

      private boolean equalsByValue(ImmutableElitism another)

    • hashCode

      public int hashCode()
      Computes a hash code from attributes: offspringSelectionPolicy, atLeastNumOffsprings, survivorSelectionPolicy, atLeastNumSurvivors, offspringRatio.
      Overrides:
      hashCode in class Object
      Returns:
      hashCode value

    • toString

      public String toString()
      Prints the immutable value Elitism with attribute values.
      Overrides:
      toString in class Object
      Returns:
      A string representation of the value

    • validate

      private static ImmutableElitism validate(ImmutableElitism instance)

    • copyOf

      public static Elitism copyOf(Elitism instance)
      Creates an immutable copy of a Elitism value. Uses accessors to get values to initialize the new immutable instance. If an instance is already immutable, it is returned as is.
      Parameters:
      instance - The instance to copy
      Returns:
      A copied immutable Elitism instance
