Detailed Description

The multithread-supported hash table, holding buckets.

Todo:

Improve the efficiency of build phase

Constructor & Destructor Documentation

MultiThreadHashTable()

INTELLI::MultiThreadHashTable::MultiThreadHashTable

(

size_t

bks

)

pre-init with several buckets

Parameters

bks	the number of buckets

Member Function Documentation

buildTable() [1/2]

void INTELLI::MultiThreadHashTable::buildTable	(	TuplePtr *	tps,
		size_t	len
	)

size_t INTELLI::MultiThreadHashTable::probeTuple

(

TuplePtr

tp

)

probe one tuple

Parameters

tp

Tge tuple

Returns

Number of matches
