Instances of this class process event built data containing XIA DDAS sources. Data from sources known not to contain DDAS data are ignored.
For the most part, other than the input data, this class
operates in the same manner as
DAQ::DDAS::DDASUnpacker,
CDDASBuiltUnpacker(const std::set<uint32_t>& validSourceIds, CParameterMapper& rParameterMapper);
validSourceIds represents the
set of event fragment source ids that are assumed
to contain DDAS data. Fragments with source ids
not in validSourceIds are
not processsed by this event processor. Presumably
another event processor works on those.
The rParameterMapper
is a reference to an object that is from a class
derived from
DAQ::DDAS::CParameterMapper that
is responsible for taking data from each decoded hit
and turning it into a set of SpecTcl parameters.
Since this is a reference and the object is not copy constructed (there's no requirement that it be copy constructable), it is important that the actual object passed remains in scope for the lifetime of the unpacker object.
void setValidSourceIds(const std::set<uint32_t>& validSourceIds);
Replaces the set of source ids that will be processed with a new set. With a statically composed DAQ you should probably never need to call this.
const std::set<uint32_t> getValidSourceIds();
Returns the current set of valid source ids. These are the data sources who's fragments will not be ignored by this event processor.
void setParameterMapper(CParameterMapper& rParameterMapper);
Provdes a new parameter mapper object.
const CParameterMapper& getParameterMapper();
Returns a reference to the current parameter mapping
object for this object. See
DAQ::DDAS::DDASUpnacker::getParameterMapper
for a sample use of this method.
virtual Bool_t operator()(const const Address_t pEvent, CEvent& rEvent, CAnalyzer& rAnalyzer, CBufferDecoder& rDecoder);
This is the method called to process raw events
pointed to by pEvent. The
crate, slot and channel numbers of all raw hits are
marshalled into a vector of
DAQ::DDAS::DDASHit objects
which is then passed to the parameter mapping object.
