Detailed Description

Identifies a location in the Ecal readout chain.

– fiber : optical fiber number (backend number), range assumed O(0-96) – elink : electronic link number, range assumed O(0-47) – channel : channel-on-elink, range O(0-37)

For transient use only i.e. we use this ID to help translate the digitized data coming off the detector into spatially-important EcalIDs.

EcalElectronicsID() [1/4]

ldmx::EcalElectronicsID::EcalElectronicsID ( )

inline

Empty ECAL id (but not null!)

: DetectorID(EID_ECAL, 0) {}

EcalElectronicsID() [2/4]

ldmx::EcalElectronicsID::EcalElectronicsID ( RawValue  rawid )

Create from raw number.

Importantly, this is NOT the PackedIndex value, it is the entire raw value including the subsystem ID.

Create from a DetectorID, but check.

idFromIndex()

static EcalElectronicsID ldmx::EcalElectronicsID::idFromIndex ( unsigned int  index )

inlinestatic

Construct an electronics id from an index.

This looks ugly (and it is) because we already have a constructor that uses the unsigned int type. This means we need a different static method for translating something we know to be an EID index rather than a full DetID raw value.
