java.lang.Object
net.bmahe.genetics4j.core.spec.replacement.ImmutableDeleteNLast.Builder
Direct Known Subclasses:
DeleteNLast.Builder
Enclosing class:
ImmutableDeleteNLast
public static class ImmutableDeleteNLast.Builder extends Object
Builds instances of type ImmutableDeleteNLast. Initialize attributes and then invoke the build() method to create an immutable instance.

Builder is not thread-safe and generally should not be stored in a field or collection, but instead used immediately to create instances.

      public Builder()
      Creates a builder for ImmutableDeleteNLast instances. 
       new DeleteNLast.Builder()

  • Method Details

    • from

      public final DeleteNLast.Builder from(DeleteNLast instance)
      Fill a builder with attribute values from the provided DeleteNLast instance. Regular attribute values will be replaced with those from the given instance. Absent optional values will not replace present values.
      Parameters:
      instance - The instance from which to copy values
      Returns:
      this builder for use in a chained invocation

    • weakRatio

      public final DeleteNLast.Builder weakRatio(double weakRatio)
      Initializes the value for the weakRatio attribute.

      If not set, this attribute will have a default value as returned by the initializer of weakRatio.

      Parameters:
      weakRatio - The value for weakRatio
      Returns:
      this builder for use in a chained invocation

    • offspringSelectionPolicy

      public final DeleteNLast.Builder offspringSelectionPolicy(SelectionPolicy offspringSelectionPolicy)
      Initializes the value for the offspringSelectionPolicy attribute.
      Parameters:
      offspringSelectionPolicy - The value for offspringSelectionPolicy
      Returns:
      this builder for use in a chained invocation

    • build

      public ImmutableDeleteNLast build()
      Builds a new ImmutableDeleteNLast.
      Returns:
      An immutable instance of DeleteNLast
      Throws:
      IllegalStateException - if any required attributes are missing

    • weakRatioIsSet

      private boolean weakRatioIsSet()

    • formatRequiredAttributesMessage
