Definition at line 39 of file IoModules/EventHandle.h.

TTree* io::EventHandle::fEventTree [protected]

The input event tree. Definition at line 48 of file IoModules/EventHandle.h.

int io::EventHandle::fIndex [protected]

Location in current input file. Definition at line 45 of file IoModules/EventHandle.h.

TFile* io::EventHandle::fInputFile [protected]

Pointer to input source. Not owned. Definition at line 46 of file IoModules/EventHandle.h.

TFile* io::EventHandle::fOutputFile [protected]

Pointer to output file. Not owned. Definition at line 47 of file IoModules/EventHandle.h.

const int io::EventHandle::fSplitLevel = 99 [static, protected]

If you set split level to 0, the tree will be written in one branch which is not very efficient Definition at line 42 of file IoModules/EventHandle.h.
