void ThingsTSelector::begin

(

TList *&

in

)

[virtual]

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.

[private]

void ThingsTSelector::postProcessing

(

TList &

out

)

[virtual]

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.

{
}

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

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

)

[virtual]

Call each time the 'slave' gets a new Event

Parameters:

event

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