Detailed Description

Event store to keep the last n events in a TTree which is _not_ saved to a file.

Allows to view the event structure from the tree and to perform TTree::Draw actions on the last events by means of dynamic list. May contain ring buffer functionality.

Member Function Documentation

Int_t TGo4BackStore::Store (  TGo4EventElement *  event  )  [virtual]

Stores eventelement event into the storage implementation. Implements TGo4EventStore. Definition at line 133 of file TGo4BackStore.cxx. References TGo4Log::Debug(), fbBranchExists, fgiMAXAUTOBYTES, fiBufsize, fiSplit, fxEvent, fxTree, and TRACE.

Int_t TGo4BackStore::Store (  TGo4Parameter *  cali  )  [virtual]

Saves a calibration object correllated with the current event into the storage. Reimplemented from TGo4EventStore. Definition at line 112 of file TGo4BackStore.cxx.

Int_t TGo4BackStore::Store (  TGo4Condition *  conny  )  [virtual]

Saves a condition correllated with the current event into the storage. Reimplemented from TGo4EventStore. Definition at line 117 of file TGo4BackStore.cxx.

Int_t TGo4BackStore::Store (  TGo4Fitter *  fitter  )  [virtual]

Saves a fitter correllated with the current event into the storage. Reimplemented from TGo4EventStore. Definition at line 122 of file TGo4BackStore.cxx.

Int_t TGo4BackStore::Store (  TFolder *  fold  )  [virtual]

Saves a folder correllated with the current event into the storage. Reimplemented from TGo4EventStore. Definition at line 127 of file TGo4BackStore.cxx.

virtual TTree* TGo4BackStore::GetTree (   )  [inline, virtual]

void TGo4BackStore::Reset (  Bool_t  onlyclearflag = kFALSE  )

Dynamic list might reset backstore after processing. If onlyclearflag is true, do not reset tree, but just unmark the "backstore was reset" bit. Definition at line 96 of file TGo4BackStore.cxx.

Member Data Documentation

const Text_t TGo4BackStore::fgcEVBRANCHNAME = "Go4EventBranch." [static]

Standard go4 name of the branch used in all treestore and treesource implementations. Definition at line 32 of file TGo4BackStore.cxx.

const Text_t TGo4BackStore::fgcTREESUF = "xTree" [static]
