Class ImmutableFloatChromosomeSpec.Builder

java.lang.Object
net.bmahe.genetics4j.core.spec.chromosome.ImmutableFloatChromosomeSpec.Builder
Direct Known Subclasses:
FloatChromosomeSpec.Builder
Enclosing class:
ImmutableFloatChromosomeSpec
public static class ImmutableFloatChromosomeSpec.Builder extends Object
Builds instances of type ImmutableFloatChromosomeSpec. 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 ImmutableFloatChromosomeSpec instances. 
       new FloatChromosomeSpec.Builder()
    .size(int) // required size
    .minValue(float) // required minValue
    .maxValue(float) // required maxValue
    .distribution(net.bmahe.genetics4j.core.spec.statistics.distributions.Distribution) // optional distribution
    .build();

  • Method Details

    • from

      public final FloatChromosomeSpec.Builder from(FloatChromosomeSpec instance)
      Fill a builder with attribute values from the provided FloatChromosomeSpec 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

    • size

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

    • minValue

      public final FloatChromosomeSpec.Builder minValue(float minValue)
      Initializes the value for the minValue attribute.
      Parameters:
      minValue - The value for minValue
      Returns:
      this builder for use in a chained invocation

    • maxValue

      public final FloatChromosomeSpec.Builder maxValue(float maxValue)
      Initializes the value for the maxValue attribute.
      Parameters:
      maxValue - The value for maxValue
      Returns:
      this builder for use in a chained invocation

    • distribution

      public final FloatChromosomeSpec.Builder distribution(Distribution distribution)
      Initializes the value for the distribution attribute.

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

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

    • build

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