Interface RealValued

All Known Implementing Classes:
BoundedRealVector, CauchyMutation, GaussianMutation, RealVector, SingleReal, UndoableCauchyMutation, UndoableGaussianMutation, UndoableUniformMutation, UniformMutation
public interface RealValued
An interface to define the parameters to a function, where the function parameters are represented as type double (i.e., as double precision floating point numbers). Classes implementing this interface may be applicable for real-valued function optimization problems.

  • Method Details

    • length

      int length()
      Gets the number of parameters.
      Returns:
      The number of parameters for this function.

    • get

      double get(int i)
      Accesses the current value of a specified parameter.
      Parameters:
      i - The parameter to get.
      Returns:
      The current value of the i-th parameter.
      Throws:
      ArrayIndexOutOfBoundsException - if i < 0 or i ≥ length().

    • toArray

      double[] toArray(double[] values)
      Accesses the current values of all of the parameters.
      Parameters:
      values - An array to hold the result. If values is null or if values.length is not equal to this.length(), then a new array is constructed for the result.
      Returns:
      An array containing the current values of all of the parameters.

    • set

      void set(int i, double value)
      Sets a function parameter to a specified value.
      Parameters:
      i - The parameter to set.
      value - The new value for the i-th parameter.
      Throws:
      ArrayIndexOutOfBoundsException - if i < 0 or i ≥ length().

    • set

      default void set(double[] values)
      Sets all values from an array (copies values from the array).
      Parameters:
      values - an array of new values
