Detailed Description

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

Constructor & Destructor Documentation

__init__()

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
