Detailed Description

template<class T, class JEvaluator_t = JNullType>
struct JSUPPORT::JTreeScannerInterface< T, JEvaluator_t >

Auxiliary interface for direct access of elements in ROOT TChain.

Specialiation of interface JTreeScannerInterface for ordered direct access of elements in ROOT TChain.

The optional second template argument is used to the determine the value of an element which defines the apparent order the elements in the TChain.

This interface extends the JTreeScannerInterface<JClass_t, JNullType> interface with the additional interface method to find a corresponding entry in the ROOT TChain.
