Product

trait Product extends Equals

Base trait for all products, which in the standard library include at least scala.Product1 through scala.Product22 and therefore also their subclasses scala.Tuple1 through scala.Tuple22.

Base trait for all products, which in the standard library include at least scala.Product1 through scala.Product22 and therefore also their subclasses scala.Tuple1 through scala.Tuple22. In addition, all case classes implement Product with synthetically generated methods.

Value members

Abstract methods

The size of this product.

Returns: for a product A(x1, ..., xk), returns k

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 Params

n: the index of the element to return

Returns

the element n elements after the first element

Throws

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

Concrete methods

The name of the nth element of this product, 0-based.

The name of the nth element of this product, 0-based. In the default implementation, an empty string.

Value Params

n: the index of the element name to return

Returns

the name of the specified element

Throws

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

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

An iterator over all the elements of this product.

Returns: in the default implementation, an Iterator[Any]

A string used in the toString methods of derived classes.

A string used in the toString methods of derived classes. Implementations may override this method to prepend a string prefix to the result of toString methods.

Returns: in the default implementation, the empty string

Inherited methods

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

A method that should be called from every well-designed equals method that is open to be overridden in a subclass. See Programming in Scala, Chapter 28 for discussion and design.

Value Params

that: the value being probed for possible equality

Returns

true if this instance can possibly equal that, otherwise false
