Member Function Documentation

void sdbf_set::add ( class sdbf * hash )

Adds a single hash to this set

Parameters:

hash	an existing sdbf hash

void sdbf_set::add ( sdbf_set * hashset )

Adds all items in another set to this set

Parameters:

hashset sdbf_set* to be added

class sdbf * sdbf_set::at ( uint32_t pos )

Accessor method for a single sdbf* in this set

Parameters:

pos	position 0 to size()

Returns:: sdbf* or NULL if position not valid

void sdbf_set::compare_all ( int32_t threshold )

Compares each sdbf object in target to every other sdbf object in target and prints the results to stdout

Parameters:

threshold output threshold, defaults to 1

std::string sdbf_set::compare_all_quiet	(	int32_t	threshold,
		int32_t	thread_count
	)

Compares each sdbf object in target to every other sdbf object in target and returns the results as a list stored in a string

Parameters:

threshold	output threshold, defaults to 1
thread_count	processor threads to use, 0 for all available

Returns:: std::string result listing

std::string sdbf_set::compare_to_quiet	(	sdbf_set *	other,
		int32_t	threshold,
		uint32_t	sample_size,
		int32_t	thread_count
	)

Compares each sdbf object in other to each object in this set, and returns the results as a list stored in a string.

Parameters:

other	set to compare to
threshold	output threshold, defaults to 1
sample_size	size of bloom filter sample. send 0 for no sampling
thread_count	processor threads to use, 0 for all available

Returns:: std::string result listing

int sdbf_set::empty ( )

Checks empty status of container

Returns:: int 1 if empty, 0 if non-empty

uint64_t sdbf_set::filter_count ( )

Returns the size of the set's own bloom_filter vector.

std::string sdbf_set::index_results ( ) const

Generates a string representing the indexing results of this set

uint64_t sdbf_set::input_size ( )

Computes the data size of this set, from the input_size() values of its' content sdbf hashes.

Returns:: uint64_t total of input sizes

std::string sdbf_set::name ( ) const

Retrieve name of this set

Returns:: string name

void sdbf_set::set_name ( std::string name )

Change name of this set

Parameters:

name of string

Number of items in this set

Returns:: uint64_t number of items in this set

std::string sdbf_set::to_string ( ) const

Generates a string which contains the output-encoded sdbfs in this set

Returns:: std::string containing sdbfs.

void sdbf_set::vector_init ( )

Sets up bloom filter vector. Should also be called by server process when done hashing to a set
