Detailed Description

Define an event processor for DDAS data.

The class defines a functor that can be created and invoked from main() to do the job of processing ring items from a source and handing them off to a data sink.

Constructor & Destructor Documentation

CEventProcessor()

CEventProcessor::CEventProcessor

(

)

Constructor.

No real action occurs until the operator() is called, as all of the interesting data must be determined by parsing the command line arguments.

Member Function Documentation

operator()()

int CEventProcessor::operator()	(	int	argc,
		char *	argv[]
	)

Entry point for the processor.

Parameters

argc	Number of command line arguments.
argv	Command line arguments.

Exceptions

std::invalid_argument	If the item skip count is invalid.
std::invalid_argument	If the dump count is invalid.
...	All other exceptions back to caller (main).

Returns

When done processing items.

Return values

EXIT_SUCCESS

Processing successful.

Here we:

• Parse arguments,
• Open the data source,
• Read data event-by-event,
• Invoke a processor to process the individual ring items.

Todo:

(ASC 1/20/23): Awkward way to process the sample and exclude types. Can we return a vector of uint16_t or whatever the CDataSourceFactory wants? Item type codes are uint32_t so why are we mixing between signed/unsigned ints and different bits?

Todo:

(ASC 3/10/23): To support different NSCLDAQ data formats, we need to read the version string from the args and create an appropriate ring item factory. The ROOT converter should be independent of the data format since we can hand it CPhysicsEventItems from the correct format type.
