   [use case]

   Returns a new parallel iterable containing the elements from the left hand operand followed by the elements from the right hand operand. The element type of the parallel iterable is the most specific superclass encompassing the element types of the two operands.

   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 traversable to append.

   returns

   Applies a binary operator to a start value and all elements of this parallel iterable, going left to right.

   Applies a binary operator to a start value and all elements of this parallel iterable, going left to right.

   Note: `/:` is alternate syntax for `foldLeft`; `z /: xs` is the same as `xs foldLeft z`.

   Examples:

   Note that the folding function used to compute b is equivalent to that used to compute c.

       scala> val a = LinkedList(1,2,3,4)
       a: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2, 3, 4)

       scala> val b = (5 /: a)(_+_)
       b: Int = 15

       scala> val c = (5 /: a)((x,y) => x + y)
       c: Int = 15

   Note: will not terminate for infinite-sized collections.

   Note: might return different results for different runs, unless the underlying collection type is ordered. or the operator is associative and commutative.

   z

     the start value.

   op

     the binary operator.

   returns

     the result of inserting `op` between consecutive elements of this parallel iterable, going left to right with the start value `z` on the left:

         op(...op(op(z, x_1), x_2), ..., x_n)

8. #### def :\[S](z: S)(op: (S, S) ⇒ S): S

   Applies a binary operator to all elements of this parallel iterable and a start value, going right to left.

   Note: `:\` is alternate syntax for `foldRight`; `xs :\ z` is the same as `xs foldRight z`.

   Note: will not terminate for infinite-sized collections.

   Note: might return different results for different runs, unless the underlying collection type is ordered. or the operator is associative and commutative.

   Examples:

   Note that the folding function used to compute b is equivalent to that used to compute c.

       a: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2, 3, 4)

       b: Int = 15

       scala> val c = (a :\ 5)((x,y) => x + y)
       c: Int = 15

   z

     the start value

   op

     the binary operator

   returns

     the result of inserting `op` between consecutive elements of this parallel iterable, going right to left with the start value `z` on the right:

    Test two objects for equality.

    Test two objects for equality. The expression `x == that` is equivalent to `if (x eq null) that eq null else x.equals(that)`.

    returns

      `true` if the receiver object is equivalent to the argument; `false` otherwise.

11. #### def aggregate[S](z: S)(seqop: (S, S) ⇒ S, combop: (S, S) ⇒ S): S

    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 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).

    S

      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

12. #### 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.

    Creates a combiner factory.

    Creates a combiner factory. Each combiner factory instance is used once per invocation of a parallel transformer method for a single collection.

    The default combiner factory creates a new combiner every time it is requested, unless the combiner is thread-safe as indicated by its `canBeShared` method. In this case, the method returns a factory which returns the same combiner each time. This is typically done for concurrent parallel collections, the combiners of which allow thread safe access.

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

    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`).

    returns

      `true` if the argument is a reference to the receiver object; `false` otherwise.

    [use case]

    Builds a new collection by applying a function to all elements of this parallel iterable and using the elements of the resulting collections.

    For example:

        def getWords(lines: Seq[String]): Seq[String] = lines flatMap (line => line split "\\W+")

    The type of the resulting collection is guided by the static type of parallel iterable. This might cause unexpected results sometimes. For example:

        // lettersOf will return a Seq[Char] of likely repeated letters, instead of a Set
        def lettersOf(words: Seq[String]) = words flatMap (word => word.toSet)

        // lettersOf will return a Set[Char], not a Seq
        def lettersOf(words: Seq[String]) = words.toSet flatMap (word => word.toSeq)

        // xs will be a an Iterable[Int]
        val xs = Map("a" -> List(11,111), "b" -> List(22,222)).flatMap(_._2)

    f

        // xs == List(1, 2, 3, 1, 2, 3)

     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.

     Converts this parallel iterable to a map. This method is unavailable unless the elements are members of Tuple2, each ((T, U)) becoming a key-value pair in the map.
