Detailed Description

Raw data unpacker for unbuilt data.

The user should use this to process data upstream of or in the absence of the event builder. This processes raw data and generates one DDASHit object per event. The user is expected to derive a class from the ParameterMapper base class and pass that object to this unpacker to call at the end of parsing each event. In that way, this class will deal with the raw data and allow the user to interact with it at a much higher level. This class will take ownership of the user's mapper and will attempt to delete it at the time of destruction. For that reason, it is important that the user dynamically allocates their mapper on the heap. A proper way to do this is:

MyParameterMapper* pMapper = new MyParameterMapper;
CDDASUnpacker unpacker(*pMapper);

This unpacker does not support byte-swapping. Don't worry, it is not likely to be an issue in the future unless you try to analyze your system on a computer with a strange architecture.

Constructor & Destructor Documentation

DAQ::DDAS::CDDASUnpacker::CDDASUnpacker

(

CParameterMapper &

rParameterMapper

)

Constructor.

Parameters

rParameterMapper

user's mapper (must be dynamically allocated, ownership transfers to class)

DAQ::DDAS::CDDASUnpacker::~CDDASUnpacker

(

)

Destructor

Member Function Documentation

CParameterMapper & DAQ::DDAS::CDDASUnpacker::getParameterMapper

(

)

const

Retrieve the active parameter

Bool_t DAQ::DDAS::CDDASUnpacker::operator() ( const Address_t  pEvent, CEvent &  rEvent, CAnalyzer &  rAnalyzer, CBufferDecoder &  rDecoder  )

virtual

Process the raw data and call user's mapper.

This is designed to process data from the DDAS readout program. See the documentation in readout to understand the structure.

This sets the event size in the CEvent.

Parameters

pEvent	address in buffer to begin parsing at
rEvent	current SpecTcl event
rAnalyzer	the analyzer
rDecoder	current buffer decoder

void DAQ::DDAS::CDDASUnpacker::setParameterMapper

(

CParameterMapper &

pParameterMapper

)

Pass in a different parameter mapper.

The user must allocate the parameter dynamically before passing it in. For example:

auto pMapper = new MyParameterMapper;
unpacker.setParameterMapper(*pMapper);

Ownership of the mapper is transferred into this object.

Parameters

rParameterMapper

the user's parameter mapper
