copy from spark

A simple, fixed-size bit set implementation. This implementation is fast because it avoids safety/bound checking.

    AnyRef → Any
  5. def ^(other: BitSet): BitSet

    Compute the symmetric difference by performing bit-wise XOR of the two sets returning the result.

  6. def andNot(other: BitSet): BitSet

    Definition Classes
    Any
  8. def capacity: Int

    Compute the capacity (number of bits) that can be represented by this bitset.

  9. def cardinality(): Int

    Return the number of bits set to true in this BitSet.

  10. def clear(): Unit

    Clear all set bits.

  11. def clearUntil(bitIndex: Int): Unit

    Clear all the bits up to a given index

  16. def get(index: Int): Boolean

    Return the value of the bit with the specified index.

    Return the value of the bit with the specified index. The value is true if the bit with the index is currently set in this BitSet; otherwise, the result is false.

    index

    the bit index

    returns

    the value of the bit with the specified index

    Definition Classes
    Any
  20. def iterator: Iterator[Int]

    Get an iterator over the set bits.

  21. final def ne(arg0: AnyRef): Boolean
    Definition Classes
    AnyRef
  22. def nextSetBit(fromIndex: Int): Int

    Returns the index of the first bit that is set to true that occurs on or after the specified starting index.

    Returns the index of the first bit that is set to true that occurs on or after the specified starting index. If no such bit exists then -1 is returned.

    To iterate over the true bits in a BitSet, use the following loop:

    for (int i = bs.nextSetBit(0); i >= 0; i = bs.nextSetBit(i+1)) { // operate on index i here }

    fromIndex

    the index to start checking from (inclusive)

    returns

    the index of the next set bit, or -1 if there is no such bit

  25. def set(index: Int): Unit

    Sets the bit at the specified index to true.

    Sets the bit at the specified index to true.

    index

    the bit index

  26. def setUntil(bitIndex: Int): Unit

    Set all the bits up to a given index
