Detailed Description

The top class package of Nested Loop Join providing a "join function".

Note
Just single thread, the threads parameter is useless

Member Function Documentation

◆ join() [1/2]

size_t NestedLoopJoin::join ( C20Buffer< OoOJoin::TrackTuplePtr >  windS,
C20Buffer< OoOJoin::TrackTuplePtr >  windR,
int  threads = 1 
)
virtual

The function to execute join,.

Parameters
windSThe window of S tuples
windRThe window of R tuples
threadsThe threads for executing this join
Note
The threads parameter will be ignored
Returns
The joined tuples

Reimplemented from OoOJoin::AbstractJoinAlgo.

int  threads = 1 
)
virtual

The function to execute join, window to tuple.

Parameters
windSThe window of S tuples
trThe tuple r
threadsThe threads for executing this join
Note
The threads parameter will be ignored
Returns
The joined tuples
