Detailed Description

ReaderListener class.

Simple implementation of a reader listener. Callback functions can be set using lambda function, std::function objects or resulting call of std::bind call.

Example with lambda functions:

ReaderListener listener ;
listener.onEventRead( [](std::shared_ptr<EventStore> event){
  std::cout << "Read event uid " << event->uid() << std::endl ;
}) ;
listener.onRunHeaderRead( [](std::shared_ptr<RunHeader> rhdr){
  std::cout << "Read run info no " << rhdr->runNumber() << std::endl ;
}) ;

Example with std::bind and custom class method:

using namespace std::placeholders ;
UserClass user ;
ReaderListener listener ;
listener.onEventRead( std::bind(&UserClass::processEvent, &user, _1) ) ;
listener.onRunHeaderRead( std::bind(&UserClass::processRunHeader, &user, _1) ) ;
