2. #### abstract def -(elem: A): Repr

3. #### abstract def /:[B](z: B)(op: (B, A) ⇒ B): B

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

   Applies a binary operator to a start value and all elements of this collection or iterator, 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 = List(1,2,3,4)
       a: List[Int] = List(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 collection or iterator, going left to right with the start value `z` on the left:

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

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

4. #### abstract def :\[B](z: B)(op: (A, B) ⇒ B): B

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

   Applies a binary operator to all elements of this collection or iterator 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 = List(1,2,3,4)
       a: List[Int] = List(1, 2, 3, 4)

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

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

   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 collection or iterator, going right to left with the start value `z` on the right:

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

5. #### abstract 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) and may be evaluated more than once

   seqop

     an operator used to accumulate results within a partition

   combop

     an associative operator used to combine results from different partitions

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.

    Tests whether this set is a subset of another set.

    Tests whether this set is a subset of another set.

    that

      the set to test.

    returns

      `true` if this set is a subset of `that`, i.e. if every element of this set is also an element of `that`.

42. #### abstract def sum: A

    [use case] Sums up the elements of this collection.

    [use case]

    Sums up the elements of this collection.

    returns

      the sum of all elements in this general set of numbers of type `Int`. Instead of `Int`, any other type `T` with an implicit `Numeric[T]` implementation can be used as element type of the general set and as result type of `sum`. Examples of such types are: `Long`, `Float`, `Double`, `BigInt`.

    [use case]

    Converts this general set into another by copying all elements.

    Converts this general set to an array.

46. #### abstract def toMap[T, U]: Map[T, U]

    [use case] Converts this general set to a map.

    [use case]

    Converts this general set 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. Duplicate keys will be overwritten by later keys: if this is an unordered collection, which key is in the resulting map is undefined.

    Note: will not terminate for infinite-sized collections.

    returns

      a map of type `immutable.Map[T, U]` containing all key/value pairs of type `(T, U)` of this general set.

52. #### abstract def zip[B](that: GenIterable[B]): GenSet[(A, B)]

    [use case] Returns a general set formed from this general set and another iterable collection by combining corresponding elements in pairs.

    [use case]

    Returns a general set formed from this general set and another iterable collection by combining corresponding elements in pairs. If one of the two collections is longer than the other, its remaining elements are ignored.

    Note: might return different results for different runs, unless the underlying collection type is ordered.

    B

      the type of the second half of the returned pairs

    that

      The iterable providing the second half of each result pair

    returns

      a new general set containing pairs consisting of corresponding elements of this general set and `that`. The length of the returned collection is the minimum of the lengths of this general set and `that`.

    [use case] Returns a general set formed from this general set and another iterable collection by combining corresponding elements in pairs.

    [use case]

    Returns a general set formed from this general set and another iterable collection by combining corresponding elements in pairs. If one of the two collections is shorter than the other, placeholder elements are used to extend the shorter collection to the length of the longer.

    Note: might return different results for different runs, unless the underlying collection type is ordered.

    B

      the type of the second half of the returned pairs

    that

    thatElem

      the element to be used to fill up the result if `that` is shorter than this general set.

    returns

      a new general set containing pairs consisting of corresponding elements of this general set and `that`. The length of the returned collection is the maximum of the lengths of this general set and `that`. If this general set is shorter than `that`, `thisElem` values are used to pad the result. If `that` is shorter than this general set, `thatElem` values are used to pad the result.
