Detailed Description

template<typename T>
class geo::TPCDataContainer< T >

Container with one element per geometry TPC.

---

Template Parameters

T	type of the contained datum

See also

geo::GeometryCore::makeTPCData

The container is of fixed size and can't be neither resized nor freed before destruction.

This example creates a "map" of tracks starting on each TPC:

auto const* geom = lar::providerFrom<geo::GeometryCore>();
geo::TPCDataContainer<std::vector<recob::Track const*>> TracksPerTPC
  (geom->NCryostats(), geom->MaxTPCs());

for (recob::Track const& track: tracks) {
  geo::TPCGeo const* tpc = geom->PositionToTPCptr(track.Start());
  if (tpc) TracksPerTPC[tpc->ID()].push_back(tpc);
} // for

Assumptions

The following assumptions should be considered unchecked, and the behavior when they are violated undefined (but note that in debug mode some of them might be actually checked):

• the container assumes the same number of TPCs in each cryostat. While this is not effectively a necessary condition, keep in mind that this container has no notion whether a given TPC actually exists in the geometry or not
• at least one element is expected to be present

Constructor & Destructor Documentation

template<typename T >

geo::TPCDataContainer< T >::TPCDataContainer ( unsigned int  nCryo, unsigned int  nTPCs  )

inline

Prepares the container with default-constructed data.

Parameters

nCryo	number of cryostats
nTPCs	number of TPCs

The container is sized to host data for nCryo cryostats, each with nTPCs TPCs. Each element in the container is default-constructed.

template<typename T >

geo::TPCDataContainer< T >::TPCDataContainer ( unsigned int  nCryo, unsigned int  nTPCs, T const &  defValue  )

inline

Prepares the container with copies of the specified default value.

Parameters

nCryo	number of cryostats
nTPCs	number of TPCs
defValue	the value to be replicated

The container is sized to host data for nCryo cryostats, each with nTPCs TPCs. Each element in the container is a copy of defValue.

auto const* geom = lar::providerFrom<geo::GeometryCore>();
geo::TPCDataContainer<unsigned int> PlanesPerTPC
  (geom->NCryostats(), geom->MaxTPCs(), 3U);
