[source: scala/collection/BitSetLike.scala]
trait BitSetLike[+This <: BitSetLike[This] with Set[Int]]
extends SetLike[Int, This]
common base class for mutable and immutable bit sets
Since
2.8
Direct Known Subclasses:
BitSet, BitSet, BitSet
Method Summary
def & (other : BitSet) : This
A new bitset which is the logical and of this set and the given argument set.
def &~ (other : BitSet) : This
A new bitset which is the logical and-not of this set and the given argument set.
def ^ (other : BitSet) : This
A new bitset which is the logical exclusive or of this set and the given argument set.
override def addString (sb : StringBuilder, start : java.lang.String, sep : java.lang.String, end : java.lang.String) : StringBuilder
Add bitset elements as numbers to string buffer
def contains (elem : Int) : Boolean
Does the set contain the given element?
abstract def empty : This
override def foreach [B](f : (Int) => B) : Unit
Apply a function f to all elements of this iterable object.
protected abstract def fromArray (elems : Array[Long]) : This
Create a new set of this kind from an array of longs
def iterator : Iterator[Int]
Creates a new iterator over all elements contained in this iterable object.
protected abstract def nwords : Int
The number of words (each with 64 bits) making up the set
override def size : Int
The number of elements in the bitset.
override def stringPrefix : java.lang.String
Defines the prefix of this object's toString representation.
def subSet (other : BitSet) : Boolean
Is the set a subset of the given bitset
protected abstract def word (idx : Int) : Long
The words at index `idx', or 0L if outside the range of the set
def | (other : BitSet) : This
A new bitset which is the logical or of this set and the given argument set.

Method Details
abstract def empty : This
Overrides
SetLike.empty
protected abstract def nwords : Int
The number of words (each with 64 bits) making up the set
protected abstract def word(idx : Int) : Long
The words at index `idx', or 0L if outside the range of the set
Precondition
idx >= 0
protected abstract def fromArray(elems : Array[Long]) : This
Create a new set of this kind from an array of longs
override def size : Int
The number of elements in the bitset.
def iterator : Iterator[Int]
Creates a new iterator over all elements contained in this iterable object.
Returns
the new iterator
override def foreach[B](f : (Int) => B) : Unit
Apply a function f to all elements of this iterable object.
Parameters
f - A function that is applied for its side-effect to every element. The result (of arbitrary type U) of function `f` is discarded.
Notes
This method underlies the implementation of most other bulk operations. Implementing `foreach` with `iterator` is often suboptimal. So `foreach` should be overridden in concrete collection classes if a more efficient implementation is available.
def |(other : BitSet) : This
A new bitset which is the logical or of this set and the given argument set.
def &(other : BitSet) : This
A new bitset which is the logical and of this set and the given argument set.
def &~(other : BitSet) : This
A new bitset which is the logical and-not of this set and the given argument set.
def ^(other : BitSet) : This
A new bitset which is the logical exclusive or of this set and the given argument set.
def contains(elem : Int) : Boolean
Does the set contain the given element?
Overrides
SetLike.contains
def subSet(other : BitSet) : Boolean
Is the set a subset of the given bitset
override def addString(sb : StringBuilder, start : java.lang.String, sep : java.lang.String, end : java.lang.String) : StringBuilder
Add bitset elements as numbers to string buffer
override def stringPrefix : java.lang.String
Defines the prefix of this object's toString representation.
Overrides
SetLike.stringPrefix
