Detailed Description

The class to describe a simplest window.

Note

Must init before feed

Constructor & Destructor Documentation

Window()

OoOJoin::Window::Window	(	OoOJoin::tsType	ts,
		OoOJoin::tsType	te
	)

vreator with range, call setRange

Parameters

ts	The start time
te	The end time

Member Function Documentation

feedTupleR()

bool OoOJoin::Window::feedTupleR

(

OoOJoin::TrackTuplePtr

tr

)

feed a tuple R into the window

Parameters

tr

The tuple

Warning

The current version is simplified and assuming only used in SINGLE THREAD!

Returns

bool, whether tuple is fed.

feedTupleS()

bool OoOJoin::Window::feedTupleS

(

OoOJoin::TrackTuplePtr

ts

)

feed a tuple s into the window

Parameters

ts

The tuple

Warning

The current version is simplified and assuming only used in SINGLE THREAD!

Returns

bool, whether tuple is fed.

getEnd()

tsType OoOJoin::Window::getEnd ( )

inline

get the end time of window

Returns

the end time

getStart()

tsType OoOJoin::Window::getStart ( )

inline

get the start time of window

Returns

the start time

init()

void OoOJoin::Window::init	(	size_t	sLen,
		size_t	rLen,
		size_t	_sysId
	)

init window with buffer/queue length and id

Parameters

sLen	The length of S queue and/or buffer
rLen	The length of S queue and/or buffer
_sysId	The system id

reset()

bool OoOJoin::Window::reset

(

void

)

reset the window, clear all tuples

Returns

bool, whether reset is done

setRange()

void OoOJoin::Window::setRange	(	OoOJoin::tsType	ts,
		OoOJoin::tsType	te
	)

To set the range of this window.

Parameters

ts	The start time
te	The end time
