Detailed Description

A class handling a collection of hits and its associations.

---

Instead of creating a collection of hits, one for its association with wires and one for its association with raw digits, one can push hits into this object, and then move it into the event.

void recob::HitAndAssociationsWriterBase::declare_products ( art::ProducesCollector &  collector, std::string  instance_name = "", bool  doWireAssns = true, bool  doRawDigitAssns = true  )

staticinherited

Declares the hit products we are going to fill.

Template Parameters

ModuleType

type of producing module (EDProducer or EDFilter)

Parameters

producer	the module producing the data products
instance_name	name of the instance for all data products
doWireAssns	whether to enable associations to wires
doRawDigitAssns	whether to enable associations to raw digits

This declaration must be given in the constructor of producer. It is equivalent to manually declare the relevant among these products:

produces<std::vector<recob::Hit>>(prod_instance);
produces<art::Assns<recob::Wire, recob::Hit>>(prod_instance);
produces<art::Assns<raw::RawDigit, recob::Hit>>(prod_instance);

in the producer constructor. All the data products (hit collection and associations) will have the specified product instance name.

	)

Adds the specified hit to the data collection.

Parameters

hit	the hit that will be moved into the collection
wire	art pointer to the wire to be associated to this hit
digits	art pointer to the raw digits to be associated to this hit

After this call, hit will be invalid. If a art pointer is not valid, that association will not be stored.

	)

Adds the specified hit to the data collection.

Parameters

hit	the hit that will be copied into the collection
wire	art pointer to the wire to be associated to this hit
digits	art pointer to the raw digits to be associated to this hit

If a art pointer is not valid, that association will not be stored.

inline

Adds the specified hit to the data collection.

Parameters

hit	the HitCreator object containing the hit
wire	art pointer to the wire to be associated to this hit
digits	art pointer to the raw digits to be associated to this hit

After this call, the hit creator will be empty. If a art pointer is not valid, that association will not be stored.

Parameters
