Detailed Description

Access TimeSlides objects in ROOT files.

This class was designed to load a collection of ROOT files containing TimeSlides objects (see the GWOLLUM convention for TimeSlides). The lag properties can then be accessed.

Constructor & Destructor Documentation

ReadTimeSlides::ReadTimeSlides	(	const string	apattern,
		const string	adirectory = "",
		const int	averbose = 0
	)

Constructor of the ReadTimeSlides class.

The ROOT files designated by the file pattern are loaded. TTrees named "slides" found in the specified directory are chained. The TTrees must follow the GWOLLUM convention for TimeSlides. In addition *all* the TTrees must be exactly the same: same number of entries and same time offsets. The number of streams is automatically detected given the tree content. There should be at least one stream.

Parameters:

	apattern	input file pattern
	adirectory	trigger ROOT directory
	averbose	verbosity level

ReadTimeSlides::~ReadTimeSlides

(

void

)

[virtual]

Destructor of the ReadTimeSlides class.
