Detailed Description

This class holds information used to decide how to merge together mergeable run products when multiple run entries with the same run number and ProcessHistoryID are read from input files contiguously.

Most of the information here is associated with the current run being processed. Most of it is cleared when a new run is started. If multiple runs are being processed concurrently, then there will be an object instantiated for each concurrent run. (At the present time concurrent runs are not possible, but there plans to implement that in the future). The primary RunPrincipal for the current run owns the object.

This class gets information from the input file from the StoredMergeableRunProductMetadata object and IndexIntoFile object. It uses that information to make the decision how to merge run products read from data, and puts information into the StoredMergeableRunProductMetadata written into the output file to use in later processing steps.

If there are SubProcesses, they use the same object as the top level process because they share the same input.

There will be a TWIKI page on the Framework page of the Software Guide which explains the details about how this works. There are significant limitations related to what the Framework does and does not do managing mergeable run products.
