Detailed Description

This is the abstract Event class.

It defines all interfaces to deal with Event data. It is a pure virtual class which does not define any implementation details (it has only member function defintions, no data members). It is meant to be subclassed by the classes which define the actual implementation.

virtual int Event::convert ( )

pure virtual

converting the Event object means that the actual data it manages are copied to an internal location and are thus safe from being overwritten. For efficiency, most Event objects initially maintain a pointer to the external raw data only. They are referred to as being pointer-based. If an Event object has already been converted, a second convert operation has no effect.

Implemented in A_Event, and oncsEvent.

Referenced by eventReceiverClient::getEvent(), and testEventiterator::getNextEvent().

Here is the caller graph for this function:

virtual int Event::Copy	(	int *	destination,
		const unsigned	int,
		int *	nw,
		const char *	= `""`
	)

pure virtual

the event's raw data are copied to destination. length is the size of destination, and nw is the number of words actually copied.

if what = "RAW" then we just copy the payload data without the event header.

Implemented in A_Event, and oncsEvent.

Referenced by prdfoStream::addEvent(), ospBuffer::addEvent(), ophBuffer::addEvent(), and main().

Here is the caller graph for this function:

virtual int Event::existPacket ( const int )

pure virtual

existPacket returns 1 if such a packet exists in the event. 0 else.

Implemented in A_Event, and oncsEvent.

Referenced by TpcMon::process_event().

Here is the caller graph for this function:

virtual int Event::getDate ( )

pure virtual

Implemented in A_Event, and oncsEvent.

virtual int Event::getErrorCode ( )

inlinevirtual

getErrorCode() returns a non-zero error code if something in the event structure is wrong. Test for 0 to see that the event passes some consistency checks.

Reimplemented in A_Event.

Here is the caller graph for this function:

virtual unsigned int Event::getEvtLength ( )

pure virtual

getEvtLength() returns the length of the event raw data in longwords (32bit). If you want to copy the event somewhere, you can find out whether or not you have enough space left.

Implemented in A_Event, and oncsEvent.

Referenced by prdfoStream::addEvent(), ospBuffer::addEvent(), ophBuffer::addEvent(), oncsBuffer::getEvent(), main(), EventCombiner::process_event(), and process_event().

Here is the caller graph for this function:

virtual int Event::getEvtSequence ( )

pure virtual

getEvtSequence() returns the number of the event in a particular run. This number is a property of the event. Its run number and the sequence number uniquely indentify an event. It has nothing to do with the position of the event in any given data file.

Implemented in A_Event, and oncsEvent.

Here is the caller graph for this function:

virtual int Event::getEvtType ( )

pure virtual

getEvtType() returns the type of the event. Most of the events have the type DATAEVENT, but there are also BEGRUNEVENT, SPILLONEVENT, SPILLOFFEVENT, ENDRUNEVENT, and so on.

Implemented in A_Event, and oncsEvent.

Referenced by hLabHelper::evDisplay(), hcalHelper::evLoop(), tileHelper::evLoop(), SingleTpcPoolInput::FillPool(), SingleGl1PoolInput::FillPool(), SingleMicromegasPoolInput::FillPool(), SingleZdcInput::FillPool(), SingleInttPoolInput::FillPool(), SingleMvtxPoolInput::FillPool(), SinglePrdfInput::FillPool(), main(), process_event(), HeadReco::process_event(), BbcMon::process_event(), PktSizeMon::process_event(), GenericUnpackPRDF::process_event(), HcalMon::process_event(), CaloUnpackPRDF::process_event(), TemplateCreation::process_event(), TpotMon::process_event(), TpcMon::process_event(), TPCPedestalCalibration::process_event(), CaloTowerBuilder::process_event(), LEDTowerBuilder::process_event(), MvtxPrototype2UnpackPRDF::process_event(), MvtxUnpackPRDF::process_event(), TpcRawDataTree::process_event(), TPCRawDataTree::process_event(), tpc_hits::process_event(), TpcRawDataDecoder::process_event(), and Fun4AllEventOutStream::WriteEvent().

Here is the caller graph for this function:

virtual unsigned int Event::getFrameEntry	(	const char *	,
		const int	= `0`,
		const int	= `0`
	)		const

inlinevirtual

getFrameEntry will return a particular entry from the frame header which contains the packet with the specidied id. If id == 0, the first frame will be selected.

keywords to return are:

FRAMELENGTH FRAMEMARK FRAMEHDRVERSION FRAMEHDRLENGTH FRAMESTATUS FRAMESOURCEID FRAMEDATATYPE FRAMETYPE FRAMEALIGNLENGTH FRAMEALIGNMENTWORD[index]

The last FRAMEALIGNMENTWORD is an array, you need to call getFrameEntry(id,"FRAMEALIGNMENTWORD",1) to get the index 1, and so on. Asking for a word beyond the number of such words will return 0.

Reimplemented in A_Event.

virtual Packet* Event::getPacket ( const int )

pure virtual

getPacket creates and returns a pointer to the packet object with the specified packet id (think of it as a house number).

Implemented in A_Event, and oncsEvent.

Here is the caller graph for this function:

virtual Packet* Event::getPacket	(	const int	,
		const int
	)

pure virtual

This interface allows to override the hitformat of the packet. For debugging purposes mostly.

Implemented in A_Event, and oncsEvent.

virtual int Event::getPacketList	(	Packet *	[],
		const int
	)

pure virtual

getPacketList returns a simple-minded array of pointers to the packets in the given event. It returns the number of packets returned in the array. The second parameter tells the packet how long the array is.

Implemented in A_Event, and oncsEvent.

Here is the caller graph for this function:

virtual unsigned int Event::getTagWord ( const int = 0 ) const

inlinevirtual

getTagWord() returns the bit pattern that the event builder may have put into the header for fast event selection purposes. This is mainly used by the ET system to distribute events based on its properties.
