RecordID EventSetup::recordID

(

const char *

iRecordName

)

const

Returns the lookup id of the record whose name is iRecordName. The returned id is only valid for the instance of an EventSetup object to which the recordID call was made. If you later create a new EventSetup instance even for the same file the RecordIDs can be different.
