inline def map[F[_]](f: [t] => (x$1: t) => F[t]): Map[this.type, F]

Called on a tuple (a1, ..., an), returns a new tuple (f(a1), ..., f(an)). The result is typed as (F[A1], ..., F[An]) if the tuple type is fully known. If the tuple is of the form a1 *: ... *: Tuple (that is, the tail is not known to be the cons type.

Inherited and Abstract methods

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.

Value parameters

that

the value being probed for possible equality

Attributes

Returns

true if this instance can possibly equal that, otherwise false

Attributes

Returns

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

Inherited from:

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
