Detailed Description

Athena Algorithm Tool to provide conversion from SCT RDO container to ByteStream.

Conversion from SCT RDO container to ByteStream, and fill it in RawEvent.

The class inherits from AthAlgTool and ISCTRawContByteStreamTool.

Contains convert method that maps ROD ID's to vectors of RDOs in those RODs, then loops through the map, using RodEncoder to fill data for each ROD in turn.

convert()

StatusCode SCTRawContByteStreamTool::convert ( const SCT_RDO_Container *  sctRDOCont ) const

overridevirtual

Main Convert method.

Maps ROD ID's to vectors of RDOs in those RODs, then loops through the map, using RodEncoder to fill data for each ROD in turn.

Parameters

sctRDOCont
