(

const int32_t

bit

)

const [inline]

get the value of the specified bit

void lucene::util::BitSet::set	(	const int32_t	bit,
		bool	val = true
	)

set the value of the specified bit

int32_t lucene::util::BitSet::size

(

)

const

returns the size of the bitset

int32_t lucene::util::BitSet::count

(

)

Returns the total number of one bits in this BitSet.

This is efficiently computed and cached, so that, if the BitSet is not changed, no recomputation is done for repeated calls.
