def canEqual(that: Any): Boolean

A method that should be called from every well-designed equals method that is open to be overridden in a subclass.

Returns:

true if this instance can possibly equal that, otherwise false

Source:
Product.scala
def productElement(n: Int): Any

The nth element of this product, 0-based.

The nth element of this product, 0-based. In other words, for a product A(x1, ..., xk), returns x(n+1) where 0 <= n < k.

Value parameters:
n

Value parameters:
n

the index of the element name to return

Returns:

the name of the specified element

Throws:
