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 ( )

default

Default constructor: empty container.

See Also: resize()

The container starts with no room for any data. The only guarantee is that empty() is true and size() is 0. Use resize() before anything else.
