Detailed Description

Creates a set of analyzers, and schedules the event processing.

Constructor & Destructor Documentation

def looper.Looper.__init__	(	self,
		name,
		config,
		nEvents = `None`,
		firstEvent = `0`,
		nPrint = `0`,
		timeReport = `False`,
		quiet = `False`,
		memCheckFromEvent = `-1`
	)

Handles the processing of an event sample.
An Analyzer is built for each Config.Analyzer present
in sequence. The Looper can then be used to process an event,
or a collection of events.

Parameters:
name    : name of the Looper, will be used as the output directory name
config  : process configuration information, see Config
nEvents : number of events to process. Defaults to all.
firstEvent : first event to process. Defaults to the first one.
nPrint  : number of events to print at the beginning
