Detailed Description

template<typename BV>
class bm::operation_deserializer< BV >

Deserializer, performs logical operations between bit-vector and serialized bit-vector.

This utility class potentially provides faster and/or more memory efficient operation than more conventional deserialization into memory bvector and then logical operation

Examples

bvsetalgebra.cpp, sample14.cpp, xsample01.cpp, and xsample07a.cpp.

deserialize() [1/2]

template<typename BV>

size_type bm::operation_deserializer< BV >::deserialize ( bvector_type & bv, const unsigned char * buf, bm::word_t * , set_operation op = bm::set_OR, bool exit_on_one = false )

inline

Obsolete! Deserialize bvector using buffer as set operation argument.

Parameters

bv	- target bvector
buf	- serialized buffer as a logical argument
op	- set algebra operation (default: OR)
exit_on_one	- quick exit if set operation found some result

Returns

bitcount (for COUNT_* operations)

		const unsigned char *	buf,
		set_operation	op,
		bool	exit_on_one = false )

Deserialize bvector using buffer as set operation argument.

Parameters

bv	- target bvector
buf	- serialized buffer used as as a logical operation argument
op	- set algebra operation (default: OR)
exit_on_one	- quick exit if set operation found some result

Returns

bitcount (for COUNT_* operations)

template<typename BV>

void bm::operation_deserializer< BV >::deserialize_range ( bvector_type & bv, const unsigned char * buf, bm::word_t * , size_type idx_from, size_type idx_to )

inline

Deserialize range using mask vector (AND)

Parameters
