Member Function Documentation

addSubEvts() [1/2]

virtual StatusCode IBkgStreamsCache::addSubEvts ( unsigned int iXing, xAOD::EventInfo * overEvent, int t0BinCenter, bool loadEventProxies, unsigned int BCID )

pure virtual

Read input events in bkg stores and link them to overlay store.

Parameters

iXing	offset to first xing number (=0 first Xing, =nXings for last xing)
overlaidEvent	reference to resulting overlaid event
t0BinCenter	time wrto t0 of current bin center in ns
BCID	bunch-crossing ID of signal bunch crossing
loadEventProxies	should we load the event proxies or not.

addSubEvts() [2/2]

virtual StatusCode IBkgStreamsCache::addSubEvts ( unsigned int iXing, xAOD::EventInfo * overlaidEvent, int t0BinCenter )

pure virtual

Read input events in bkg stores and link them to overlay store.

Parameters

iXing	offset to first xing number (=0 first Xing, =nXings for last xing)
overlaidEvent	reference to resulting overlaid event
t0BinCenter	time wrto t0 of current bin center in ns

DeclareInterfaceID()

IBkgStreamsCache::DeclareInterfaceID	(	IBkgStreamsCache	,
		1	,
		0	)

Creates the InterfaceID and interfaceID() method.

newEvent()

virtual void IBkgStreamsCache::newEvent ( )

pure virtual

inform concrete cache that we start overlaying a new event

nStores()

virtual unsigned int IBkgStreamsCache::nStores ( ) const

pure virtual

how many stores in cache

resetEvtsPerXingScaleFactor()

virtual void IBkgStreamsCache::resetEvtsPerXingScaleFactor ( float sf )

pure virtual

rescale number of events per crossing

setup()

virtual StatusCode IBkgStreamsCache::setup ( int firstXing, unsigned int nXings, unsigned int firstStore, IBeamIntensity * iBM )

pure virtual

Parameters

firstXing	index of first xing to be processed (0=t0)
nXings	number of bunch Xings to be processed
firstStore	id of first store in cache
