   [use case] Returns a new string builder containing the elements from the left hand operand followed by the elements from the right hand operand.

   [use case]

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

   Example:

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

       scala> val b = List(2)
       b: List[Int] = List(2)

       scala> val c = a ++ b
       c: List[Int] = List(1, 2)

       scala> val d = List('a')
       d: List[Char] = List(a)

       scala> val e = c ++ d
       e: List[AnyVal] = List(1, 2, a)

   B

     the element type of the returned collection.

   that

     the traversable to append.

   returns

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

6. #### def ++:[B >: Char, That](that: collection.Traversable[B])(implicit bf: CanBuildFrom[StringBuilder, 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 traversable collection followed by all elements of `that`.

    [use case]

    A copy of the string builder 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 string builder 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)

        scala> println(x)
        List(1)

    elem

      the prepended element

25. #### def aggregate[B](z: ⇒ B)(seqop: (B, Char) ⇒ 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) and may be evaluated more than once

    seqop

      an operator used to accumulate results within a partition

    Applies this partial function to the given argument when it is contained in the function domain.

    Applies this partial function to the given argument when it is contained in the function domain. Applies fallback function where this partial function is not defined.

    Note that expression `pf.applyOrElse(x, default)` is equivalent to

        if(pf isDefinedAt x) pf(x) else default(x)

    except that `applyOrElse` method can be implemented more efficiently. For all partial function literals the compiler generates an `applyOrElse` implementation which avoids double evaluation of pattern matchers and guards. This makes `applyOrElse` the basis for the efficient implementation for many operations and scenarios, such as:

    - combining partial functions into `orElse`/`andThen` chains does not lead to excessive `apply`/`isDefinedAt` evaluation
    - `lift` and `unlift` do not evaluate source functions twice on each invocation
    - `runWith` allows efficient imperative-style combining of partial functions with conditionally applied actions

    For non-literal partial function classes with nontrivial `isDefinedAt` method it is recommended to override `applyOrElse` with custom implementation that avoids double `isDefinedAt` evaluation. This may result in better performance and more predictable behavior w.r.t. side effects.

    x

      the function argument

    default

      the fallback function

    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.

    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`).

     Compares the length of this sequence to a test value.

     Compares the length of this sequence to a test value.

     len

       the test value that gets compared with the length.

     returns

       A value `x` where

           x <  0       if this.length <  len
           x == 0       if this.length == len
           x >  0       if this.length >  len

       The method as implemented here does not call `length` directly; its running time is `O(length min len)` instead of `O(length)`. The method should be overwritten if computing `length` is cheap.

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.

     [use case]

     Produces a new sequence which contains all elements of this string builder 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-presevring multi-set union of `xs` and `ys`. `union` is hence a counter-part of `diff` and `intersect` which also work on multi-sets.
