m_BlobStack.resize(0);

Serialization / compression of bvector<>. Set theoretical operations on compressed BLOBs.

Implementation of merger interface for bitsets.

bm::word_t * m_TmpBvBlock

deserialization temp block

vector< CMergeVolumes::TRawBuffer * > TRawBufferStack

virtual ~CMergeBitsetBlob()

virtual void Reset()

Reset merging, forget all the accumulated buffers.

virtual void Merge(CMergeVolumes::TRawBuffer *buffer)

Merge request Implementation MUST return the buffer to the pool.

virtual CMergeVolumes::TRawBuffer * GetMergeBuffer()

Returns destination (merged) buffer Caller MUST return the buffer to the buffer pool.

TRawBufferStack m_BlobStack

blocks to merge

TBitVector m_TmpBv

temp bit-vector

Reallocable memory buffer (no memory copy overhead) Mimics vector<>, without the overhead of explicit...

void resize(size_type new_size)

BLOB merge interface, merges one or more BLOBs together.

#define NON_CONST_ITERATE(Type, Var, Cont)

Non constant version of ITERATE macro.

Pool::TValue * Release()

Return the pointer to the caller, not to the pool.

#define END_NCBI_SCOPE

End previously defined NCBI scope.

#define BEGIN_NCBI_SCOPE

Define ncbi namespace.

size_t serialize(const BV &bv, unsigned char *buf, bm::word_t *temp_block=0, unsigned serialization_flags=0)

Saves bitvector into memory.

size_t deserialize(BV &bv, const unsigned char *buf, bm::word_t *temp_block=0, const bm::bv_ref_vector< BV > *ref_vect=0)

Bitvector deserialization from a memory BLOB.

@ BM_NO_GAP_LENGTH

save no GAP info (save some space)

@ BM_NO_BYTE_ORDER

save no byte-order info (save some space)

void aligned_free(void *ptr) BMNOEXCEPT

Aligned free.

void * aligned_new_malloc(size_t size)

Aligned malloc (unlike classic malloc it throws bad_alloc exception)

const unsigned set_block_alloc_size

const struct ncbi::grid::netcache::search::fields::SIZE size

Compressed bitset (entry point to bm.h)
