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.

Definition at line 508 of file HitCreator.h.

Constructor & Destructor Documentation

recob::HitCollectionCreator::HitCollectionCreator	(	art::Event &	event,
		std::string	instance_name = "",
		bool	doWireAssns = true,
		bool	doRawDigitAssns = true
	)

Constructor: sets instance name and whether to build associations.

Parameters

event	the event the products are going to be put into
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

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

Definition at line 278 of file HitCreator.cxx.

    : HitAndAssociationsWriterBase
      (event, instance_name, doWireAssns, doRawDigitAssns)
  {
    hits.reset(new std::vector<recob::Hit>);
  } // HitCollectionCreator::HitCollectionCreator()

recob::HitCollectionCreator::HitCollectionCreator ( art::Event &  event, bool  doWireAssns, bool  doRawDigitAssns  )

inline

Constructor: no product instance name.

Parameters

event	the event the products are going to be put into
doWireAssns	whether to enable associations to wires
doRawDigitAssns	whether to enable associations to raw digits

Definition at line 536 of file HitCreator.h.

Member Function Documentation

void recob::HitCollectionCreator::CreateAssociationsToLastHit ( art::Ptr< recob::Wire > const &  wire, art::Ptr< raw::RawDigit > const &  digits  )

protected

Creates associations between the last hit and the specified pointers.

Definition at line 327 of file HitCreator.cxx.

    {
    // if no association is required, we are done
    if (!WireAssns && !RawDigitAssns) return;

    // art pointer to the hit we just created
    HitPtr_t hit_ptr(CreatePtrToLastHit());

    // association with wires
    if (WireAssns && wire.isNonnull())
      WireAssns->addSingle(wire, hit_ptr); // if it fails, it throws

    // association with wires
    if (RawDigitAssns && digits.isNonnull())
      RawDigitAssns->addSingle(digits, hit_ptr); // if it fails, it throws

  } // HitCollectionCreator::CreateAssociationsToLastHit()

HitPtr_t recob::HitCollectionCreator::CreatePtrToLastHit ( ) const

inlineprotected

Creates an art pointer to the hit with the last index.

Definition at line 672 of file HitCreator.h.

      { return hits->empty()? HitPtr_t(): CreatePtr(hits->size() - 1); }

void recob::HitCollectionCreator::emplace_back	(	recob::Hit &&	hit,
		art::Ptr< recob::Wire > const &	wire = art::Ptr<recob::Wire>(),
		art::Ptr< raw::RawDigit > const &	digits = art::Ptr<raw::RawDigit>()
	)

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.

Definition at line 290 of file HitCreator.cxx.

    {

    // add the hit to the collection
    hits->emplace_back(std::move(hit));

    CreateAssociationsToLastHit(wire, digits);
  } // HitCollectionCreator::emplace_back(Hit&&)

void recob::HitCollectionCreator::emplace_back	(	recob::Hit const &	hit,
		art::Ptr< recob::Wire > const &	wire = art::Ptr<recob::Wire>(),
		art::Ptr< raw::RawDigit > const &	digits = art::Ptr<raw::RawDigit>()
	)

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.

Definition at line 303 of file HitCreator.cxx.

    {

    // add the hit to the collection
    hits->push_back(hit);

    CreateAssociationsToLastHit(wire, digits);
  } // HitCollectionCreator::emplace_back(Hit)

void recob::HitCollectionCreator::emplace_back ( HitCreator &&  hit, art::Ptr< recob::Wire > const &  wire = art::Ptr<recob::Wire>(), art::Ptr< raw::RawDigit > const &  digits = art::Ptr<raw::RawDigit>()  )

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.

Definition at line 590 of file HitCreator.h.

      { emplace_back(hit.move(), wire, digits); }

void recob::HitCollectionCreator::emplace_back ( recob::Hit &&  hit, art::Ptr< raw::RawDigit > const &  digits  )

inline

Adds the specified hit to the data collection.

Parameters

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

After this call, hit will be invalid. If the digit pointer is not valid, its association will not be stored.

Definition at line 606 of file HitCreator.h.

      { emplace_back(std::move(hit), art::Ptr<recob::Wire>(), digits); }

void recob::HitCollectionCreator::emplace_back ( HitCreator &&  hit, art::Ptr< raw::RawDigit > const &  digits  )

inline

Adds the specified hit to the data collection.

Parameters

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

Definition at line 618 of file HitCreator.h.

      { emplace_back(std::move(hit), art::Ptr<recob::Wire>(), digits); }

void recob::HitCollectionCreator::emplace_back ( HitCreator const &  hit, art::Ptr< raw::RawDigit > const &  digits  )

inline

Adds the specified hit to the data collection.

Parameters

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

If the digit pointer is not valid, its association will not be stored.

Definition at line 630 of file HitCreator.h.

      { emplace_back(std::move(hit.copy()), art::Ptr<recob::Wire>(), digits); }

std::vector<recob::Hit> const& recob::HitCollectionCreator::peek ( ) const

inline

Returns a read-only reference to the current list of hits.

Definition at line 665 of file HitCreator.h.

{ return *hits; }

void recob::HitCollectionCreator::put_into ( art::Event &  )

inline

Moves the data into an event.

The calling module must have already declared the production of these products with the proper instance name. After the move, the collections in this object are empty.

Deprecated:

Use the version with no arguments instead.

Definition at line 652 of file HitCreator.h.

{ put_into(); }

void recob::HitCollectionCreator::put_into

(

)

Moves the data into the event.

The calling module must have already declared the production of these products with the proper instance name. After the move, the collections in this object are empty.

                                      {
    if (!hits) {
      throw art::Exception(art::errors::LogicError)
        << "HitCollectionCreator is trying to put into the event"
        " a hit collection that was never created!\n";
    }
    HitAndAssociationsWriterBase::put_into();
  } // HitCollectionCreator::put_into()

void recob::HitCollectionCreator::reserve ( size_t  new_size )

inline

Prepares the collection to host at least new_size hits.

{ if (hits) hits->reserve(new_size); }

size_t recob::HitCollectionCreator::size ( void  ) const
