Method Detail

length

long length()

Returns "logical size" = index of highest set bit plus one. Returns zero if there are no any set bit.

Returns:

"logical size" = index of highest set bit plus one

set

void set(long fromIndex,
         long toIndex,
         boolean value)

Set all bits to value from fromIndex (inclusive) to toIndex (exclusive)

Parameters:

fromIndex - inclusive

toIndex - exclusive

value - true = 1, false = 0

clear

void clear(long fromIndex,
           long toIndex)

Set all bits to zero from fromIndex (inclusive) to toIndex (exclusive)

Parameters:

fromIndex - inclusive

toIndex - exclusive

set

void set(BitSet bs)

not

void not()

set

void set(long fromIndex,
         long toIndex)

Set all bits to one from fromIndex (inclusive) to toIndex (exclusive)

Parameters:

fromIndex - inclusive

toIndex - exclusive

size

long size()

Returns number of set bits.

Returns:

number of set bits.

get

boolean get(long bitIndex)

Returns true if bit set to one and false overwise.

Parameters:

bitIndex - - index of bit

Returns:

true if bit set to one and false overwise.

set

void set(long bitIndex)

Set bit to one at specified bitIndex

Parameters:

bitIndex - - index of bit

set

void set(long bitIndex,
         boolean value)

Set bit to value at specified bitIndex

Parameters:

bitIndex - - index of bit

value - true = 1, false = 0

toByteArray

byte[] toByteArray()

cardinality

long cardinality()

Returns the number of bits set to one.

Returns:

number of bits

clear

boolean clear(long bitIndex)

Set bit to zero at specified bitIndex

Parameters:

bitIndex - - index of bit

Returns:

true - if previous value was true, false - if previous value was false

clear

void clear()

Set all bits to zero

asBitSet

BitSet asBitSet()

or

void or(String... bitSetNames)

and

void and(String... bitSetNames)

xor

void xor(String... bitSetNames)
