Method Detail

hasAtLeastOneBitSet

public static boolean hasAtLeastOneBitSet(BitSet bitSet,
                                          Iterable<Integer> indexes)

Returns true if at least one bit on a given position is set.

Parameters:

bitSet - the BitSet to modify

indexes - the index positions to check

Returns:

true if BitSet contains at least one bit at any position from index which is set, otherwise returns false

hasAllBitsSet

public static boolean hasAllBitsSet(BitSet bitSet,
                                    Iterable<Integer> indexes)

Returns true if all bits at given indexes are set.

Parameters:

bitSet - the BitSet to modify

indexes - the index positions to check

Returns:

true if BitSet all bits at given indexes are set. otherwise returns false

setBits

public static void setBits(BitSet bitSet,
                           Iterable<Integer> indexes)

Set all bits on a given positions.

Parameters:

bitSet - the BitSet to modify

indexes - the index positions to set

unsetBits

public static void unsetBits(BitSet bitSet,
                             Iterable<Integer> indexes)

Unsets all bits on a given positions.

Parameters:

bitSet - the BitSet to modify

indexes - the index positions to set
