# Range

#### class Range extends IndexedSeq[Int] with CustomParallelizable[Int, ParRange] with Serializable

The `Range` class represents integer values in range [start;end) with non-zero step value `step`. It's a special case of an indexed sequence. For example:

        val r1 = 0 until 10
        val r2 = r1.start until r1.end by r1.step + 1
        println(r2.length) // = 5

   [use case]

   Returns a new range containing the elements from the left hand operand followed by the elements from the right hand operand. The element type of the range is the most specific superclass encompassing the element types of the two operands (see example).

   B

     the element type of the returned collection.

   that

     the traversable to append.

   returns

     a new collection of type `That` which contains all elements of this range followed by all elements of `that`.

   Definition Classes
     GenTraversableLike

5. #### def ++[B >: Int, That](that: GenTraversableOnce[B])(implicit bf: CanBuildFrom[IndexedSeq[Int], B, That]): That

   Returns a new range containing the elements from the left hand operand followed by the elements from the right hand operand.

   Returns a new range containing the elements from the left hand operand followed by the elements from the right hand operand. The element type of the range is the most specific superclass encompassing the element types of the two operands (see example).

   Example:

           scala> val a = LinkedList(1)
           a: scala.collection.mutable.LinkedList[Int] = LinkedList(1)

           scala> val b = LinkedList(2)
           b: scala.collection.mutable.LinkedList[Int] = LinkedList(2)

           scala> val c = a ++ b
           c: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2)

           scala> val d = LinkedList('a')
           d: scala.collection.mutable.LinkedList[Char] = LinkedList(a)

           scala> val e = c ++ d
           e: scala.collection.mutable.LinkedList[AnyVal] = LinkedList(1, 2, a)

   B

     the element type of the returned collection.

   That

     the class of the returned collection. Where possible, `That` is the same class as the current collection class `Repr`, but this depends on the element type `B` being admissible for that class, which means that an implicit instance of type `CanBuildFrom[Repr, B, That]` is found.

   that

     the traversable to append.

   bf

     an implicit value of class `CanBuildFrom` which determines the result class `That` from the current representation type `Repr` and the new element type `B`.

   returns

     a new collection of type `That` which contains all elements of this range followed by all elements of `that`.

   Definition Classes
     TraversableLike → GenTraversableLike

6. #### def ++:[B >: Int, That](that: Traversable[B])(implicit bf: CanBuildFrom[IndexedSeq[Int], B, That]): That

   As with `++`, returns a new collection containing the elements from the left operand followed by the elements from the right operand.

   As with `++`, returns a new collection containing the elements from the left operand followed by the elements from the right operand. It differs from `++` in that the right operand determines the type of the resulting collection rather than the left one.

   Example:

           scala> val x = List(1)
           x: List[Int] = List(1)

           scala> val y = LinkedList(2)
           y: scala.collection.mutable.LinkedList[Int] = LinkedList(2)

           scala> val z = x ++: y
           z: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2)

   This overload exists because: for the implementation of `++:` we should reuse that of `++` because many collections override it with more efficient versions.

   Since `TraversableOnce` has no `++` method, we have to implement that directly, but `Traversable` and down can use the overload.

   B

     the element type of the returned collection.

   That

     the class of the returned collection. Where possible, `That` is the same class as the current collection class `Repr`, but this depends on the element type `B` being admissible for that class, which means that an implicit instance of type `CanBuildFrom[Repr, B, That]` is found.

   that

     the traversable to append.

   bf

     an implicit value of class `CanBuildFrom` which determines the result class `That` from the current representation type `Repr` and the new element type `B`.

   returns

     a new range which contains all elements of this range followed by all elements of `that`.

    Appends all elements of this range to a string builder using start, end, and separator strings.

    Appends all elements of this range to a string builder using start, end, and separator strings. The written text begins with the string `start` and ends with the string `end`.

21. #### def aggregate[B](z: B)(seqop: (B, Int) ⇒ B, combop: (B, B) ⇒ B): B

    Aggregates the results of applying an operator to subsequent elements.

    Aggregates the results of applying an operator to subsequent elements.

    This is a more general form of `fold` and `reduce`. It has similar semantics, but does not require the result to be a supertype of the element type. It traverses the elements in different partitions sequentially, using `seqop` to update the result, and then applies `combop` to results from different partitions. The implementation of this operation may operate on an arbitrary number of collection partitions, so `combop` may be invoked an arbitrary number of times.

    For example, one might want to process some elements and then produce a `Set`. In this case, `seqop` would process an element and append it to the list, while `combop` would concatenate two lists from different partitions together. The initial value `z` would be an empty set.

           pc.aggregate(Set[Int]())(_ += process(_), _ ++ _)

    Another example is calculating geometric mean from a collection of doubles (one would typically require big doubles for this).

    B

      the type of accumulated results

    z

      the initial value for the accumulated result of the partition - this will typically be the neutral element for the `seqop` operator (e.g. `Nil` for list concatenation or `0` for summation)

    seqop

      an operator used to accumulate results within a partition

    combop

      an associative operator used to combine results from different partitions

24. #### final def asInstanceOf[T0]: T0

    Cast the receiver object to be of type `T0`.

    Cast the receiver object to be of type `T0`.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression `1.asInstanceOf[String]` will throw a `ClassCastException` at runtime, while the expression `List(1).asInstanceOf[List[String]]` will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

    returns

      the receiver object.

    Tests whether the argument (`arg0`) is a reference to the receiver object (`this`).

    The `eq` method implements an equivalence relation on non-null instances of `AnyRef`, and has three additional properties:

    - It is consistent: for any non-null instances `x` and `y` of type `AnyRef`, multiple invocations of `x.eq(y)` consistently returns `true` or consistently returns `false`.
    - For any non-null instance `x` of type `AnyRef`, `x.eq(null)` and `null.eq(x)` returns `false`.
    - `null.eq(null)` returns `true`.

    When overriding the `equals` or `hashCode` methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (`o1 eq o2`), they should be equal to each other (`o1 == o2`) and they should hash to the same value (`o1.hashCode == o2.hashCode`).

    Tests whether this range is known to have a finite size.

    Tests whether this range is known to have a finite size. All strict collections are known to have finite size. For a non-strict collection such as `Stream`, the predicate returns `true` if all elements have been computed. It returns `false` if the stream is not yet evaluated to the end.

    Note: many collection methods will not work on collections of infinite sizes.

    returns

      `true` if this collection is known to have finite size, `false` otherwise.

131. #### def par: ParRange

     Returns a parallel implementation of this collection.

     Returns a parallel implementation of this collection.

     For most collection types, this method creates a new parallel collection by copying all the elements. For these collection, `par` takes linear time. Mutable collections in this category do not produce a mutable parallel collection that has the same underlying dataset, so changes in one collection will not be reflected in the other one.

     Specific collections (e.g. `ParArray` or `mutable.ParHashMap`) override this default behaviour by creating a parallel collection which shares the same underlying dataset. For these collections, `par` takes constant or sublinear time.

     All parallel collections return a reference to themselves.
