Detailed Description

Key for IdConversion Map.

This will take the different information from the xtc and transform it to a unique key by having a comparison smaller than applied.

Unfortunately the xtc differentiats between the detector and the detectorId the detector is an enum described in Pds::DetInfo::Detector and the detector id is different. The same is true for the device. Both, the detector ids and the device ids are encoded in a single unsigned 32 bit integer. To identify a single detector it is therefore necessary to give all the information.

Constructor & Destructor Documentation

cass::lclsid::Key::Key ( const Pds::TypeId::Type &  detectorType, const Pds::DetInfo::Detector &  det, uint32_t  detId, const Pds::DetInfo::Device &  dev, uint32_t  devId  )

inline

constructor

will create the physical from the detector and device inputs. The detectorType can just be copied.

Parameters

detectorType	the type of data contained in the xtc
det	enum of the detector itself
detId	the id of the detector
dev	enum of the device of the data
devId	the id of the device

cass::lclsid::Key::Key ( const Pds::TypeId::Type &  detectorType, uint32_t  physicalId  )

inline

constructor

one can retrieve the physical id and the type id directly from the xtc. Therefore a direct assigmnet is possible.

Parameters

detectorType	the type of data contained in the xtc
physicalId	the id that has the info about device and detector encoded

check whether this is less than other

will compare for less first the _detectorType. If this is the same it will compare for less the _detector value. This makes sure that the lcls Id is unique.

Parameters

other

the other key that one compares this key to
