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)

Copy bits state of source BitSet object to this object

Parameters:

bs - - BitSet source

not

void not()

Executes NOT operation over all bits

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

boolean set(long bitIndex)

Set bit to one at specified bitIndex

Parameters:

bitIndex - - index of bit

Returns:

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

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)

Executes OR operation over this object and specified bitsets. Stores result into this object.

Parameters:
