org.jlab.io.hipo.HipoDataSourceSorted

All Implemented Interfaces:

DataSource

public class HipoDataSourceSorted
extends HipoDataSource

A wrapper on HipoDataSource to read one file sorted by CODA event number. WARNING: This is strictly for reading sorted events sequentially. Methods other than the overridden "open", "hasEvent", "getNextEvent", and "reset" may not work as intended. FIXME: Events with no HEAD bank or negative event number are unreachable.
