Class ImmutableProgram.Builder

java.lang.Object
net.bmahe.genetics4j.gp.program.ImmutableProgram.Builder
Enclosing class:
ImmutableProgram
public static final class ImmutableProgram.Builder extends Object
Builds instances of type ImmutableProgram. 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.

    • from

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

    • addFunctions

      public final ImmutableProgram.Builder addFunctions(OperationFactory element)
      Adds one element to functions set.
      Parameters:
      element - A functions element
      Returns:
      this builder for use in a chained invocation

    • addFunctions

      public final ImmutableProgram.Builder addFunctions(OperationFactory... elements)
      Adds elements to functions set.
      Parameters:
      elements - An array of functions elements
      Returns:
      this builder for use in a chained invocation

      Initializes the value for the inputSpec attribute.
      Parameters:
      inputSpec - The value for inputSpec
      Returns:
      this builder for use in a chained invocation

    • maxDepth

      public final ImmutableProgram.Builder maxDepth(int maxDepth)
      Initializes the value for the maxDepth attribute.
      Parameters:
