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.

Abstract Value Members

  1. abstract def canEqual(that: Any): Boolean

    Checks whether this instance can possibly equal that.

    Checks whether this instance can possibly equal that.

    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.

    that

    the value being probed for possible equality

    returns

    true if this instance can possibly equal that, otherwise false

    Equals
  2. abstract def productArity: Int

    The size of this product.

    The size of this product.

    returns

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

  3. abstract 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.

    n

    the index of the element to return

    returns

    the element n elements after the first element

    Exceptions thrown

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

Concrete Value Members

  1. def productElementName(n: Int): String

    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.

    n

    the index of the element name to return

    returns

    the name of the specified element

    Exceptions thrown

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

  2. def productElementNames: Iterator[String]

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

  3. def productIterator: Iterator[Any]

    An iterator over all the elements of this product.

    An iterator over all the elements of this product.

    returns

    in the default implementation, an Iterator[Any]

  4. def productPrefix: String

    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
