5.  def frequencies: Map[Element, Int]

   Constructs and returns a new map with the collection’s elements as keys and each element’s occurrence counts as the corresponding values.

   Constructs and returns a new map with the collection’s elements as keys and each element’s occurrence counts as the corresponding values. This is equivalent to mapGroups(identity)( _.size ).

6.  def getClass(): Class[_ <: AnyVal]

   Definition Classes

   AnyVal → Any

7.  def ifNonEmpty[Result](compute: (Collection[Element]) => Result): Option[Result]

   Applies the given function to the collection in case there’s at least one element there.

   Applies the given function to the collection in case there’s at least one element there. Returns None if the collection is empty.

8.  final def isInstanceOf[T0]: Boolean

   Definition Classes

   Any

9.  def log(format: (Iterable[Element]) => String = _.toString): Collection[Element]

   Prints out the collection, then returns the unmodified collection.

   Prints out the collection, then returns the unmodified collection.

   format

   a function from the collection to the desired printout; defaults to _.toString

10.  def mapFromID[ID](formID: (Element) => ID): Map[ID, Element]

    Constructs and returns a new map by applying an ID-generating function to each element of the collection and using the collection’s elements as values.

    Constructs and returns a new map by applying an ID-generating function to each element of the collection and using the collection’s elements as values. This is equivalent to calling mapify(formID)(identity).

    formID

    a function called on each element of the collection to obtain the keys

11.  def mapGroups[Key, Value](formKey: (Element) => Key)(transformGroup: (Iterable[Element]) => Value): Map[Key, Value]

    Constructs and returns a new map by using one given function to group the elements of the collection (as per groupBy) and then transforming each of the groups using another given function (as per mapValues).

    Constructs and returns a new map by using one given function to group the elements of the collection (as per groupBy) and then transforming each of the groups using another given function (as per mapValues).

    formKey

    a function called on each element of the collection to generate groups of values

    transformGroup

    a function called on each group to obtain the values for the resulting collection

12.  def mapTo[Value](formValue: (Element) => Value): Map[Element, Value]

    Constructs and returns a new map by applying a value-generating function to each element of the collection and using the collection’s elements as keys.

    Constructs and returns a new map by applying a value-generating function to each element of the collection and using the collection’s elements as keys. This is equivalent to calling mapify(identity)(formValue).

    formValue

    a function called on each element of the collection to obtain the keys

13.  def mapify[Key, Value](formKey: (Element) => Key)(formValue: (Element) => Value): Map[Key, Value]

    Constructs and returns a new map by applying a key-generating function as well as a value-generating function to each element of the collection.

    Constructs and returns a new map by applying a key-generating function as well as a value-generating function to each element of the collection. The respective outputs of the functions are paired to form the key--value pairs of the Map.

    formKey

    a function called on each element of the collection to obtain the keys

    formValue

    a function called on each element of the collection to obtain the values

14.  def slidingPairs: Iterator[(Element, Element)]

    Returns an iterator of pairs (tuples) that “slide across” the collection as per sliding.

15.  def tap(effect: (Element) => Unit): Collection[Element]

    Performs a given side effect at each element of the collection.

    Performs a given side effect at each element of the collection. Returns the unmodified collection.

16.  def toLazy: LazyList[Element]

    Returns a LazyList containing the collection’s elements.

    Returns a LazyList containing the collection’s elements. This is equivalent to to(LazyList).
