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.

Store() [1/2]

Int_t TGo4TreeStore::Store ( TGo4EventElement *  event )

overridevirtual

Stores eventelement event into the storage implementation. May be a file, a root tree, a socket to a viewer...

Implements TGo4EventStore.

Store() [2/2]

Int_t TGo4TreeStore::Store ( TGo4Parameter *  cali )

overridevirtual

Saves a calibration object correlated 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.
