Detailed Description

The abstraction to describe a join algorithm, providing virtual function of join.

Member Function Documentation

getAlgoName()

std::string OoOJoin::AbstractJoinAlgo::getAlgoName ( )

inline

get the name of algorithm

Returns

The name

join()

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

virtual

The function to execute join,.

Parameters

windS	The window of S tuples
windR	The window of R tuples
threads	The threads for executing this join

Returns

The joined tuples

Note

Please at least mark the final processed time at rTuples

Reimplemented in OoOJoin::NPJSingle, OoOJoin::NPJ, and OoOJoin::NestedLoopJoin.

setAlgoName()

void OoOJoin::AbstractJoinAlgo::setAlgoName ( std::string  name )

inline

set the name of algorithm

Parameters

name	Algorithm name

setConfig()

bool OoOJoin::AbstractJoinAlgo::setConfig ( INTELLI::ConfigMapPtr  cfg )

virtual

Set the config map related to this Algorithm.

Parameters

cfg	The config map

Returns

bool whether the config is successfully set

syncTimeStruct()

void OoOJoin::AbstractJoinAlgo::syncTimeStruct ( struct timeval  tv )

inline

Synchronize the time structure with outside setting.

Parameters

tv	The outside time structure
