Method Detail

equals

boolean equals(Object o)

Returns true if and only if the specified object is also a BitVector and both contain the same bits in the same order.

Overrides:

equals in class Object

Parameters:

o - the object to be compared with this BitVector

Returns:

true if and only if the specified object is also a BitVector and both contain the same bits in the same order

getBit

boolean getBit(long position)

This is the "access" method of bit vectors.

Returns:

value of a bit at position

Throws:

IndexOutOfBoundsException - if the position is out of range

size

long size()

Returns:

size of this bit vector

iterator

Iterator<Boolean> iterator()

Returns:

an iterator for this bit vector

addBit

boolean addBit(boolean bit)

Appends a bit to this bit vector.

Returns:

true if the element was successfully added

setBit

void setBit(long position,
            boolean bit)

Sets a bit at a particular position.

Parameters:

position - position

bit - bit

Throws:

IndexOutOfBoundsException - if the position is out of range
