Raw event source which reads entries from a root TTree in a TFile. File is opened by ctor; method BuildEvent() iterates over tree. Needs pointer to external reference to event structure class which must match the structure of the tree entry New since 10/2004: Name of event element defines tree subbranch to be activated as partial input

| Bool_t TGo4FileSource::BuildEvent | ( | TGo4EventElement * | dest | ) | [virtual] |
Fill the destination event dest from the tree. If end of tree is reached, the current event counter is reset and a kFALSE value is returned.
Reimplemented from TGo4EventSource.
