  • Method Details

    • toProperties

      public Properties toProperties()
      Returns the persistent set of hyperparameters.
      Returns:
      the persistent set.

    • of

      public static SammonMapping.Options of(Properties props)
      Returns the options from properties.
      Parameters:
      props - the hyperparameters.
      Returns:
      the options.

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

      Returns the value of the step record component.
      Returns:
      the value of the step record component

    • maxIter

      public int maxIter()
      Returns the value of the maxIter record component.
      Returns:
      the value of the maxIter record component

    • tol

      public double tol()
      Returns the value of the tol record component.
      Returns:
