error in a module using RX redundancy - add an error for the other link as well!! However, ABCDError_Chip0-ABCDError_Chip5 and TempMaskedChip0-TempMaskedChip5 are not common for two links.

overridevirtual

Fill SCT RDO Collection with decoded ROB data.

Decode the rob data fragment and fill the collection SCT_RDO_Collection with the RDO built by the makeRDO(..) method. rdoIdc, and errs are updated based on robFrag and vecHash.

Parameters

robFrag	ROB fragment.
rdoIDCont	RDO ID Container to be filled.
errs	Byte stream error container.
vecHash	Vector of hashes.

Builds RawData RDO and adds to RDO container.

Method that builds the RawData RDO and add it to the collection rdoIdc and cache are updated based on other arguments.

Returns

Method has 3 possible return values: 1 if RDO was successfully created 0 if collection was deliberately skipped (for trigger) -1 if there was an error in the decoding - will be passed on as StatusCode::RECOVERABLE by fillCollection()

Parameters

isOld	if true use data.oldStrip, otherwise use data.strip.
data	Struct to hold data shared in methods used in fillCollection method
cache	Cache.
