Detailed Description

template<class JTypelist_t = JNullType, template< class > class JFileScanner_t = JMultipleFileScanner>
struct JSUPPORT::JTriggeredFileScanner< JTypelist_t, JFileScanner_t >

Auxiliary class to synchronously read DAQ events and Monte Carlo events (and optionally other events).

It is assumed that the TTree corresponding to the template argument and the TTree with KM3NETDAQ::JDAQEvent can be read in parallel.
