Detailed Description

Template specialisation of JMultipleFileScanner for trigger parameters.

This class re-implements the methods rewind and setObject of the JLANG::JRewindableAbstractObjectIterator interface so that all trigger parameter objects in the complete file list are read and checked for consistency.
