Detailed Description

class RawDataCnvSvc Conversion Service which coordinates all of converters.

When a component requests an item not yet available on the TDS, the RawDataCnvSvc is called to find the appropriate converter to gain access to the data and put it on the TDS.

Based on GLAST's EfbCnvSvc
