Class TGo4SimpleEvent

class TGo4SimpleEvent

derived from TGo4EventElement

Simple Event structure containing a fixed size TClonesArray of subevents.
Each subevent has integer data members corresponding to the first
n longwords of the TMbsSubEvent dynamic data field. May be used to work with
quasi raw event data within the root TTreeViewer.

Field Detail

fcTestCharArr

private char [10] fcTestCharArr

private Int_t fiArrLen

private Int_t fiCount

private Int_t fiLastSlot

Index of last used slot in the clonesarray.

private Int_t fiMaxSlot

Index of last existing slot in the clonesarray.

private Int_t[10] fiTestArray

private TIterator* fxIterator

Iterator for array.

private TClonesArray* fxSubEventArray

public TGo4SimpleEvent()

public TGo4SimpleEvent(Int_t subevtnum)

public virtual synchronized ~TGo4SimpleEvent()

public TGo4SimpleSubEvent* AddSubEvent(Short_t procid)

Add subevent ito clonesarray with new procid. The pointer to the new
subevent is returned. If entry for procid already existed, this entry is
returned and the clonesarray is left as is.

public virtual void Clear(Option_t* t)

Method called by the event owner (analysis step) to clear the
event element.

public virtual Int_t Fill()

Method called by the event owner (analysis step) to fill the
event element from the set event source. Event source can
be the source of the analysis step (if this is a raw event) or the event processor (if this is a reduced event).
Fill method has to specify how the event source writes to the
members of this event structure. Either by calling methods of
the source (like myevent.a=GetEventSource()->GetA(); etc ), or by
direct copy to the member (like GetEventSource()->FillMemoryAt(&myevent.a);)

public const Int_t GetCount()

public TGo4SimpleSubEvent* GetSubEvent(Short_t procid)

Access to subevent in list by procid. Returns zero if no
subevent of this procid is found

public TGo4SimpleSubEvent* NextSubEvent()

Iterator for subevent array. If reset is kTRUE, the iteration starts at the
first TObjArray slot, otherwise we continue at the position after the last
call of this method.

public void PrintEvent()

public void ResetIterator()

Set the internal iterator of the subevent array to the beginning of
the array.
