4. #### def ++[B](that: GenTraversableOnce[B]): Iterable[B]

   [use case]

   [use case]
   B

     the element type of the returned collection.

   that

     the traversable to append.

   returns

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

   Definition Classes
     TraversableViewLike → TraversableLike → GenTraversableLike

5. #### def ++:[B >: A, That](that: Traversable[B])(implicit bf: CanBuildFrom[IterableView[A, Coll], 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. Mnemonic: the COLon is on the side of the new COLlection type.

   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 and the new element type `B`.

   returns

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

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

   Applies a binary operator to a start value and all elements of this iterable collection, 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.

   B

     the result type of the binary operator.

   z

     the start value.

   op

     the binary operator.

   returns

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

                     op(...op(op(z, x1), x2), ..., xn)

     where `x1, ..., xn` are the elements of this iterable collection.

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

   Applies a binary operator to all elements of this iterable collection 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.

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

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

   B

     the result type of the binary operator.

   op

     the binary operator

   returns

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

14. #### def addString(b: StringBuilder, sep: String): StringBuilder

    Appends all elements of this iterable collection to a string builder using a separator string.

    Appends all elements of this iterable collection to a string builder using a separator string. The written text consists of the string representations (w.r.t. the method `toString`) of all elements of this iterable collection, separated by the string `sep`.

15. #### def aggregate[B](z: B)(seqop: (B, A) ⇒ 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

16. #### 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.

    Definition Classes
      Any
    Exceptions thrown
      ClassCastException

    Method called from equality methods, so that user-defined subclasses can refuse to be equal to other collections of the same kind.

    Method called from equality methods, so that user-defined subclasses can refuse to be equal to other collections of the same kind.

    that

      The object with which this iterable collection should be compared

    returns

30. #### final def eq(arg0: AnyRef): Boolean

    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.
