  6. def productElement(n: Int): Any

    Returns the n-th projection of this product if 0 <= n < productArity, otherwise throws an IndexOutOfBoundsException.

    Returns the n-th projection of this product if 0 <= n < productArity, otherwise throws an IndexOutOfBoundsException.

    n

    number of the projection to be returned

    returns

    same as ._(n+1), for example productElement(0) is the same as ._1.

    Annotations
    @throws(clazz = classOf[IndexOutOfBoundsException])
    Exceptions thrown

    IndexOutOfBoundsException if the n is out of range(n < 0 || n >= 4).

  7. def productElementNames: Iterator[String]

    An iterator over the names of all the elements of this product.

  8. def toString(): String

    Creates a String representation of this object.

    Creates a String representation of this object. The default representation is platform dependent. On the java platform it is the concatenation of the class name, "@", and the object's hashcode in hexadecimal.

    returns

    a String representation of the object.
