Detailed Description

Storage instance using the central main go4 tree which is accessible as singleton.

Each treestore instance adds at least one new branch to that tree and fills it with the data at the event pointer. Branch associated with this tree store may be written to the main tree file, or be located in another file which is specified by the filename parameter of ctor.

Member Function Documentation

Int_t TGo4TreeStore::Store (  TGo4EventElement *    event )  [virtual]

Stores eventelement event into the storage implementation. May be a file, a root tree, a socket to a viewer... Implements TGo4EventStore. Definition at line 146 of file TGo4TreeStore.cxx. References TGo4EventElement::Clear(), TGo4Log::Debug(), fcEventClass, fxBranch, fxEvent, TGo4EventElement::SetValid(), and TRACE.

void TGo4TreeStore::SetCompression (  Int_t    comp )

Set the file compression level. May be changed on the fly. Definition at line 197 of file TGo4TreeStore.cxx. References fxFile, and TRACE.

Int_t TGo4TreeStore::Store (  TGo4Parameter *    cali )  [virtual]

Saves a calibration object correllated with the current event into the storage. This method is optional, i.e. it needs not to be implemented for all subclasses. Reimplemented from TGo4EventStore. Definition at line 175 of file TGo4TreeStore.cxx. References TGo4MainTree::fxFile, fxSingletonTree, TGo4MainTree::GetCurrentIndex(), and TRACE.
