Member Function Documentation

void ThingsTSelector::begin ( TList *&  in )

overridevirtual

Called each time the 'client' begins processing (remote 'slaves' do not see this message)

Parameters

in	an assignable pointer to a list of objects you want passed to 'preProcessing'. This list is used to communicate with remote slaves. NOTE: you are responsible for deleting this TList and its content once you are done with it.

void ThingsTSelector::postProcessing ( TList &  out )

overridevirtual

Called each time the 'slave' has seen all the events

Parameters

out	the list of objects that will be sent to 'terminate'. You can Add() additional objects to 'out' at this point as well.

{}

void ThingsTSelector::preProcessing ( const TList *  in, TList &  out  )

overridevirtual

Called each time the 'slave' is about to start processing

Parameters

in	a pointer to the list of objects created in 'begin()'. The pointer can be 0
out	a list of objects that are the result of processing (e.g. histograms). You should call 'Add()' for each object you want sent to the 'terminate' method.

void ThingsTSelector::process ( const edm::Event &  event )

overridevirtual

Parameters

event

a standard edm::Event which works just like it does in cmsRun
