    • Method Detail

      • get

        public boolean get​(long index)
        Returns the state of the bit at the given index.

      • set

        public void set​(long index)
        Sets the bit at the given index to true.

      • set

        public void set​(long startIndex,
                long endIndex)
        Sets the bits from the startIndex (inclusive) to the endIndex (exclusive).

      • getAndSet

        public boolean getAndSet​(long index)
        Sets a bit and returns the previous value. The index should be less than the BitSet size.

      • flip

        public void flip​(long index)
        Toggles the bit at the given index.

      • cardinality

        public long cardinality()
        Returns the number of set bits in the bit set.

        Note: this method is not thread-safe.

      • isEmpty

        public boolean isEmpty()
        Returns true iff no bit is set.

        Note: this method is not thread-safe.

      • allSet

        public boolean allSet()

        Note: this method is not thread-safe.

      • capacity

        public long capacity()
        Returns the number of bits this bitset can hold.

      • size

        public long size()
        Returns the number of bits in the bitset.

      • clear

        public void clear()
        Resets all bits in the bit set.

        Note: this method is not thread-safe.

      • clear

        public void clear​(long index)
