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`
	)

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)

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