Introduction

This package is meant to provide the mapping between online and offline identifiers for each detector element. By online identifier we mean the way a detector element is uniquely identified in the bytestream (i.e. the ROD number and the link of the ROD). It also provides the mapping between a ROB and the offline identifiers which are included in that ROB.

The present clients are the BS converters and the Region Selector used in the HLT.

Class Overview

SCT_Cabling contains the following classes:

ISCT_CablingTool: Pure Abstract Baseclass giving accessor methods for SCT_CablingTool. This is the main interface for clients.
SCT_CablingTool: Inheriting from ISCT_CablingTool and AthAlgTool: Provides accessor methods for the data structures it reads using SG::ReadCondHandle. The data are prepared by SCT_CablingCondAlgFromCoraCool or SCT_CablingCondAlgFromText.
SCT_OnlineId: A stand-alone class for the online id, which is an encoding of the rod and fibre used to readout a particular module.
SCT_SerialNumber: A stand-alone class for the serial number, which is a 14 digit code associated with each SCT module at its manufactire.
SCT_CablingData: A class to hold the data necessary for SCT_CablingTool. This class is filled by SCT_CablingCondAlgFromCoraCool or SCT_CablingCondAlgFromText for SCT_CablingTool.
SCT_CablingCondAlgFromCoraCool: A condition algorithm for SCT_CablingTool. This is used to fill the cabling from the database.
SCT_CablingCondAlgFromText: A condition algorithm for SCT_CablingTool. This is used to fill the cabling from a text file.
SCT_TestCablingAlg: A test algorithm which instantiates the cabling service and loops over all possible modules, calling methods to show the online Id and serial number for each one.

SCT_CablingTool in Detail

SCT_CablingTool is accessed by clients through its ISCT_CablingTool interface. This provides access only to the 'getter' methods. The cabling data are prepared by a condition algorithm (SCT_CablingCondAlgFromCoraCool or SCT_CablingCondAlgFromText)from the database or a text file and the data are read by SCT_CablingTool using SG::ReadCondHandle.
