Class ImmutableMultiPointArithmetic.Builder

java.lang.Object
net.bmahe.genetics4j.core.spec.combination.ImmutableMultiPointArithmetic.Builder
Enclosing class:
ImmutableMultiPointArithmetic

public static final class ImmutableMultiPointArithmetic.Builder extends Object
Builds instances of type ImmutableMultiPointArithmetic. 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.

  • Method Details

    • from

      Fill a builder with attribute values from the provided MultiPointArithmetic 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
    • numCrossovers

      public final ImmutableMultiPointArithmetic.Builder numCrossovers(int numCrossovers)
      Initializes the value for the numCrossovers attribute.
      Parameters:
      numCrossovers - The value for numCrossovers
      Returns:
      this builder for use in a chained invocation
    • alpha

      public final ImmutableMultiPointArithmetic.Builder alpha(double alpha)
      Initializes the value for the alpha attribute.

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

      Parameters:
      alpha - The value for alpha
      Returns:
      this builder for use in a chained invocation
    • build

      Returns:
      An immutable instance of MultiPointArithmetic
      Throws:
      IllegalStateException - if any required attributes are missing
    • alphaIsSet

      private boolean alphaIsSet()
    • formatRequiredAttributesMessage

      private String formatRequiredAttributesMessage()
