◆ get_lastrun()

int TRestDataBase::get_lastrun ( )

virtual

get the latest run id in database

get the latest run in database

Get the latest run in database, by reading the file: $REST_USER_PATH/runNumber. Note that this file saves run number of the next run. So it returns The run number -1.

◆ query_data()

DBEntry TRestDataBase::query_data ( DBEntry _info )

virtual

metadata management interface ////////////////////// return the piece of data in fMetadataEntries

The following specification of DBEntry's content means to match any: id <= 0, type == "" ,usr == "" ,tag == "" ,description == "" ,version == "". If all of them mean any, it will return a blank list.

◆ query_run()

virtual DBEntry TRestDataBase::query_run ( int runnumber )

inlinevirtual

run number management interface ////////////////////// return the run number of the run. If not exist, return 0

Definition at line 104 of file TRestDataBase.h.

◆ set_run()

int TRestDataBase::set_run	(	DBEntry	info,
		bool	overwrite = `true`
	)

virtual

add/update a run, with run info as struct DBEntry. returns the added run id

add a new run, with run info as struct DBEntry. returns the added run id

runs are added according to info.id of input DBEntry object: -1 --> do not add 0 --> append a new run in run list >0 --> directly use this run number, overwrite existing

It will write to the file: $REST_USER_PATH/runNumber is writable. The number written will be the next run number

The method in derived class shall follow this rule.
