The class allows to encode the position within a 32-bit "key" and, conversely, unpack a 32-bit key to provide the position. The class provides the following member data: - FED key (32 bits), - FED id, - Front-End unit ("external" numbering scheme), - channel within a Front-End unit ("external" numbering scheme), - APV number within a channel (or, equivalently, an APV pair). - directory path, - "granularity". Member data (integer in type only) with values of 0xFFFF signifies "invalid" (ie, FedId = 0xFFFF means "invalid FED id"). Data with null values signifies "all" (ie, FedId = 0 means "all FEDs"). The class generates a "directory path" string according to the member data. This can be used to organise histograms / other data types when using DQM / root. Conversely, the member data can also be built using the directory path when provided as a constructor argument. The class also provides the "granularity" to which the FED key is unambiguous (ie, not "invalid" or "null") in defining a position within the readout system. In addition, the class provides static methods that allow to convert between the two "FED channel" numbering schema in place. The class member data hold values that respect the "external" numbering scheme used by the optical links group. Front-End units are numbered from 1 to 8, bottom to top. Channels with the FE units are numbered 1 to 12, bottom to top. The "internal" numbering scheme is used by the DAQ software, which numbers FED channels consecutively from 0 to 95, top to bottom. */ class SiStripFedKey : public SiStripKey { public: // ---------- Constructors ---------- /** Constructor using FED id, FE unit, FE channel, and APV. */ SiStripFedKey(const uint16_t& fed_id, const uint16_t& fe_unit = 0, const uint16_t& fe_chan = 0, const uint16_t& fed_apv = 0); /** Constructor using 32-bit "FED key". */ SiStripFedKey(const uint32_t& fed_key); /** Constructor using directory path. */ SiStripFedKey(const std::string& directory_path); /** Copy constructor. */ SiStripFedKey(const SiStripFedKey&); /** Copy constructor using base class. */ SiStripFedKey(const SiStripKey&); /** Default constructor */ SiStripFedKey(); /** Assignment operator */ SiStripFedKey& operator=(const SiStripFedKey&) = default; // ---------- Public interface to member data ---------- /** Returns FED id. */ inline const uint16_t& fedId() const; /** Returns Front-End unit (according to "external" numbering). */ inline const uint16_t& feUnit() const; /** Returns chan of FE unit (according to "external" numbering). */ inline const uint16_t& feChan() const; /** Returns APV within FED channel. */ inline const uint16_t& fedApv() const; /** Returns FED channel (according to "internal" numbering). */ inline uint16_t fedChannel() const; // ---------- Numbering schemes ---------- /** Returns FED channel ("internal" numbering scheme) for given Front-End unit and channel ("external" numbering scheme). */ static uint16_t fedCh(const uint16_t& fe_unit, const uint16_t& fe_chan); /** Returns Front-End unit ("external" numbering scheme) for given FED channel ("internal" numbering scheme). */ static uint16_t feUnit(const uint16_t& fed_ch); /** Returns Front-End channel ("external" numbering scheme) for given FED channel ("internal" numbering scheme). */ static uint16_t feChan(const uint16_t& fed_ch); /** Returns number that encodes FED id and FED channel, which can be used to index vectors containing event and non-event data.
