#define BM_MINISET_ARRSIZE(x)

#define BM_MINISET_GAPLEN

Bitvector class with very limited functionality.

const unsigned * get_buf() const

int is_bit_true(size_type pos) const

Checks if bit pos 1 or 0. Returns 0 if 0 and non zero otherwise.

unsigned mem_used() const

size_type get_first() const

Returns index of the first ON bit.

size_type get_next(size_type idx) const

Returns index of next bit, which is ON.

void combine_sub(const bvector_mini &bvect)

void swap(bvector_mini &bvm)

size_type bit_count() const

Counts number of bits ON.

bvector_mini(size_type size)

void combine_and(const bvector_mini &bvect)

void combine_or(const bvector_mini &bvect)

void combine_xor(const bvector_mini &bvect)

int compare(const bvector_mini &bvect)

Comparison.

bvector_mini(const bvector_mini &bvect)

void clear_bit(size_type pos)

Sets bit number pos to 0.

void set_bit(size_type pos)

Sets bit number pos to 1.

Bitvector Bit-vector container with runtime compression of bits.

size_type get_next(size_type prev) const noexcept

Finds the number of the next bit ON.

size_type get_first() const noexcept

find first 1 bit in vector. Function may return 0 and this requires an extra check if bit 0 is actual...

Mini bit-vector for auxiliary purposes.

unsigned mem_used() const

void set(bm::id_t n, bool val=true)

unsigned test(bm::id_t n) const

Checks if bit pos 1 or 0. Returns 0 if 0 and non zero otherwise.

bvmini(const bvmini &mset)

bm::word_t m_buf[((N/32)+((N % 32) &&1))]

Template class implements memory saving set functionality.

void init_bitbuf(bm::word_t *buf)

void set(bm::id_t n, bool val=true)

unsigned mem_used() const

void init_gapbuf(bm::word_t *buf)

bm::word_t * m_buf

Buffer pointer.

miniset(const miniset &mset)

unsigned m_type

buffer type (0-bit, 1-gap)

unsigned test(bm::id_t n) const

Checks if bit pos 1 or 0. Returns 0 if 0 and non zero otherwise.

unsigned gap_test(const T *buf, unsigned pos) noexcept

Tests if bit = pos is true.

void gap_convert_to_bitset(unsigned *dest, const T *buf, unsigned len=0) noexcept

GAP block to bitblock conversion.

unsigned gap_set_value(unsigned val, T *buf, unsigned pos) noexcept

Sets or clears bit in the GAP buffer.

void gap_set_all(T *buf, unsigned set_max, unsigned value) noexcept

Sets all bits to 0 or 1 (GAP)

const unsigned set_word_shift

unsigned long long int id64_t

unsigned short gap_word_t
