BitSet

class BitSet extends AnyRef

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

  12. 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

  17. 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

  20. def set(index: Int): Unit

    Sets the bit at the specified index to true.

    index
