Detailed Description

Access metadata in trigger files.

This class is designed to read triggers metadata stored in TTrees saved in ROOT files. It should be used when you are only interested by the metadata content of trigger files. Only the segment and metadata contents of the files are loaded so this class is much faster than the ReadTriggers class since the triggers are never loaded. This is quite useful when hundreds of files need to be scanned.

Author: Florent Robinet

Constructor & Destructor Documentation

◆ ReadTriggerMetaData()

ReadTriggerMetaData::ReadTriggerMetaData	(	const string	aPattern,
		const string	aDirectory = `""`,
		const unsigned int	aVerbose = `0`
	)

Constructor of the ReadTriggerMetaData class.

The segment tree and the metadata tree in ROOT files designated by a file pattern are scanned.

The metadata parameters (frequency, Q, and SNR) are scanned and the absolute minimum/maximum is found.

The metadata may also include a list of options. The options are downloaded as a GwollumOptions object.

The segment tree in the input files are also downloaded. These segments can be accessed using the methods of the Segments class from which this class inherits.

The stream name in the metadata is used to initiate the Streams object.

Warning: When scanning the files, the reference process name and stream name are determined from the first file. Then, if, for the next files, the process name or the stream name changes, files are skipped.

Note: The process version and the username are extracted from the last file.

Parameters

[in]	aPattern	Input file pattern.
[in]	aDirectory	ROOT subdirectory. Use "" if none.
[in]	aVerbose	Verbosity level.
