override final def toString : java.lang.String

Returns a string representation of the object.

The default representation is platform dependent.

Returns: a string representation of the object.

override def productPrefix : java.lang.String

By default the empty string. Implementations may override this method in order to prepend a string prefix to the result of the toString methods.

Parameters: n - the index of the element to return
Throws: IndexOutOfBoundsException -
Returns: The element n elements after the first element

Overrides: Product.productElement
