# BitSet

#### class BitSet extends AbstractSet[Int] with SortedSet[Int] with BitSet with BitSetLike[BitSet] with SetLike[Int, BitSet] with Serializable

A class for mutable bitsets.

Bitsets are sets of non-negative integers which are represented as variable-size arrays of bits packed into 64-bit words. The memory footprint of a bitset is determined by the largest number stored in it.

For `null` returns a hashcode where `null.hashCode` throws a `NullPointerException`.

    [use case]

    [use case]
    B

      the element type of the returned collection.

    that

      the traversable to append.

    returns

12. #### def ++:[B >: Int, That](that: Traversable[B])(implicit bf: CanBuildFrom[BitSet, 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. In the standard library configuration, `That` is always `BitSet[B]` because an implicit of type `CanBuildFrom[BitSet, B, BitSet]` is defined in object `BitSet`.

    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 the new element type `B`. This is usually the `canBuildFrom` value defined in object `BitSet`.

    returns

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

    Appends all elements of this bitset 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 bitset, separated by the string `sep`.

34. #### def aggregate[B](z: B)(seqop: (B, Int) ⇒ 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

    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.

58. #### 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.

     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.

             set(elem) = false // removes element

     elem
