Product

scala.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. In addition, all case classes implement Product with synthetically generated methods.

Value members

Abstract methods

The size of this product.

Attributes

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

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: the index of the element to return

Attributes

Returns: the element n elements after the first element
Throws: IndexOutOfBoundsException if the n is out of range(n < 0 || n >= productArity).
Source: Product.scala

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 parameters

n: the index of the element name to return

Attributes

Returns: the name of the specified element
Throws: IndexOutOfBoundsException if the n is out of range(n < 0 || n >= productArity).
Source: Product.scala

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

Attributes

Source: Product.scala

An iterator over all the elements of this product.

Attributes

Returns: in the default implementation, an Iterator[Any]
Source: Product.scala

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.

Attributes

Returns: in the default implementation, the empty string
Source: Product.scala

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 parameters

that: the value being probed for possible equality

Attributes

Returns: true if this instance can possibly equal that, otherwise false
