   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.

   That

   bf

   [use case]

   A copy of the immutable parallel vector with an element prepended.

   Note that :-ending operators are right associative (see example). A mnemonic for +: vs. :+ is: the COLon goes on the COLlection side.

   Also, the original immutable parallel vector is not modified, so you will want to capture the result.

   Example:

   scala> val x = List(1)
   x: List[Int] = List(1)
   
   scala> val y = 2 +: x
   y: List[Int] = List(2, 1)

9.  def aggregate[S](z: ⇒ S)(seqop: (S, T) ⇒ 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 set, while combop would concatenate two sets 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) and may be evaluated more than once

    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.

    Tests whether the argument (that) 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.

    Tests whether this parallel iterable 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. Non-empty Iterators usually return false even if they were created from a collection with a known finite size.

    Note: many collection methods will not work on collections of infinite sizes. The typical failure mode is an infinite loop. These methods always attempt a traversal without checking first that hasDefiniteSize returns true. However, checking hasDefiniteSize can provide an assurance that size is well-defined and non-termination is not a concern.

     Transposes this collection of traversable collections into a collection of collections.

     The resulting collection's type will be guided by the static type of collection. For example:

     val xs = List(

                Set(4, 5, 6)).transpose

     val ys = Vector(
                List(1, 2, 3),
                List(4, 5, 6)).transpose

     [use case]

     Produces a new sequence which contains all elements of this immutable parallel vector and also all elements of a given sequence. xs union ys is equivalent to xs ++ ys.

     Another way to express this is that xs union ys computes the order-preserving multi-set union of xs and ys. union is hence a counter-part of diff and intersect which also work on multi-sets.

     Note: will not terminate for infinite-sized collections.

     the sequence to add.

     returns

     a new immutable parallel vector which contains all elements of this immutable parallel vector followed by all elements of that.
