# BitSet

#### class BitSet extends AbstractSet[Int] with SortedSet[Int] with collection.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.

11. #### def ++[B](that: GenTraversableOnce[B]): BitSet[B]

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

    [use case]

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

    Example:

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

        scala> val b = LinkedList(2)
        b: scala.collection.mutable.LinkedList[Int] = LinkedList(2)

        scala> val c = a ++ b
        c: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2)

        scala> val d = LinkedList('a')
        d: scala.collection.mutable.LinkedList[Char] = LinkedList(a)

        scala> val e = c ++ d
        e: scala.collection.mutable.LinkedList[AnyVal] = LinkedList(1, 2, a)

    B

      the element type of the returned collection.

    that

      the traversable to append.

    returns

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

    #### def ++[B >: Int, That](that: GenTraversableOnce[B])(implicit bf: CanBuildFrom[BitSet, B, That]): That

12. #### def ++:[B >: Int, That](that: collection.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`.

    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

Therefore the expression `1.asInstanceOf[String]` will throw a `ClassCastException` at runtime, while the expression `List(1).asInstanceOf[List[String]]` will not.

    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`).

      `true` if the argument is a reference to the receiver object; `false` otherwise.

Therefore the expression `1.isInstanceOf[String]` will return `false`, while the expression `List(1).isInstanceOf[List[String]]` will return `true`. 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 specified type.

     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.

     Produces a collection containing cumulative results of applying the operator going right to left.

     Produces a collection containing cumulative results of applying the operator going right to left. The head of the collection is the last cumulative result.

     Example:

         List(1, 2, 3, 4).scanRight(0)(_ + _) == List(10, 9, 7, 4, 0)

     B

       the type of the elements in the resulting collection

     That

       the actual type of the resulting collection

     z

       the initial value

     op

       the binary operator applied to the intermediate result and the element

     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

197. #### def withFilter(p: (Int) ⇒ Boolean): FilterMonadic[Int, BitSet]

     Creates a non-strict filter of this bitset.

     Creates a non-strict filter of this bitset.

     Note: the difference between `c filter p` and `c withFilter p` is that the former creates a new collection, whereas the latter only restricts the domain of subsequent `map`, `flatMap`, `foreach`, and `withFilter` operations.

     p

       the predicate used to test elements.

     returns

       an object of class `WithFilter`, which supports `map`, `flatMap`, `foreach`, and `withFilter` operations. All these operations apply to those elements of this bitset which satisfy the predicate `p`.

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

     [use case]

     Returns a bitset formed from this bitset 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.

     B

       the type of the second half of the returned pairs

     that

       The iterable providing the second half of each result pair

     thisElem

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

     thatElem

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

     returns

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