  • Method Details

    • contains

      public boolean contains(int i)
      Description copied from interface: IntSet
      Whether this set contains the given int
      Parameters:
      i - the int to check
      Returns:
      if the set contains the int

    • containsAll

      public boolean containsAll(IntSet set)
      Description copied from interface: IntSet
      Whether this set contains all ints in the given IntSet
      Parameters:
      set - the set to check if all are present
      Returns:
      if the set contains all the ints

    • size

      public int size()

    • isEmpty

      public boolean isEmpty()

    • contains

      public boolean contains(Object o)

    • iterator

      public PrimitiveIterator.OfInt iterator()
      Description copied from interface: IntSet
      A primtive iterator that allows iteration over the int values. This iterator supports removal if the set is modifiable.
      Returns:
      the iterator

    • toBitSet

      public byte[] toBitSet()
      Description copied from interface: IntSet
      Returns a byte array that has a bit set for each int in this set where each byte represents 8 numbers. That is if the ints 2, 5 and 9 are set this will return a byte array consisting of 2 bytes in little-endian representation of those values.

      Depending upon the implementation this array may or may not have trailing bytes and may be condensed to save space.

      Returns:
      a byte array containing a little-endian representation of all the ints of this int set as bits

    • nextSetBit

      public int nextSetBit(int fromIndex)
      Description copied from interface: IntSet
      Returns the next int in the set that is greater than or equal to the given value.
      Parameters:
      fromIndex - : inclusive index to start searching.
      Returns:
      the index of the next set bit, or -1 if there is no such bit

    • toArray

      public Object[] toArray()

    • toArray

      public <T> T[] toArray(T[] a)

    • toIntArray

      public int[] toIntArray()
      Description copied from interface: IntSet
      Returns an array containing all of the elements in this set. If this set makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.
      Returns:
      this int set as an array

    • containsAll

      public boolean containsAll(Collection<?> c)

    • intStream

      public IntStream intStream()
      Description copied from interface: IntSet
      A stream of ints representing the data in this set
      Returns:
      the stream

    • forEach

      public void forEach(IntConsumer action)
      Description copied from interface: IntSet
      Performs the given action for each int of the IntSet until all elements have been processed or the action throws an exception. Unless otherwise specified by the implementing class, actions are performed in the order of iteration (if an iteration order is specified). Exceptions thrown by the action are relayed to the caller.

      The default implementation behaves as if: 

      
     PrimitiveIterator.OfInt iterator = iterator();
     while (iterator.hasNext()) {
        action.accept(iterator.nextInt());
     }
      Parameters:
      action - The action to be performed for each element

    • forEach

      public void forEach(Consumer<? super Integer> action)

    • intSpliterator

      public Spliterator.OfInt intSpliterator()
      Description copied from interface: IntSet
      Creates a Spliterator.OfInt over the ints in this set.

      The Spliterator.OfInt reports Spliterator.DISTINCT. Implementations should document the reporting of additional characteristic values. The default implementation creates a late-binding spliterator from the set's Iterator. The spliterator inherits the fail-fast properties of the set's iterator.

      The created Spliterator.OfInt additionally reports Spliterator.SIZED. The created Spliterator.OfInt additionally reports Spliterator.SUBSIZED.

      Returns:
      a Spliterator.OfInt over the ints in this set
