Member Function Documentation

begin()

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.

Implements TFWLiteSelectorBasic.

Definition at line 15 of file ThingsTSelector.cc.

{}

operator=()

ThingsTSelector tfwliteselectortest::ThingsTSelector::operator= ( ThingsTSelector const &  )

private

postProcessing()

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.

Implements TFWLiteSelectorBasic.

Definition at line 74 of file ThingsTSelector.cc.

{}

preProcessing()

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.

process()

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

overridevirtual

Call each time the 'slave' gets a new Event

Parameters

event

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

Implements TFWLiteSelectorBasic.

terminate()

void ThingsTSelector::terminate ( TList &  out )

overridevirtual

Parameters

out	contains the accumulated output of all slaves.
