Iterators
Two types of iterators are provided: "standard" iterators pointing to data values "item" pseudo-iterators dereferencing to a (ID, value) pair Reverse iterators are not supported (yet?). Standard iterators The STL-like interface provides iterators that go through the entire range of allowed data, i.e. all the size() elements that are also reached via random access (operator[]()). These iterators have an interface extension: the data member ID() returns the ID of the element the iterator is pointing to. For example: auto iData = data.begin(); auto const dend = data.end(); while (iData != dend) { std::cout << "data[" << iData.ID() << "] = " << *iData << std::endl; ++iData; } // while Note that using the range-for loop, you don't get access to the iterator and therefore not even to the ID. Item iterators The item iterators are iterators adapted from the standard ones, which when dereferenced return a pair ( ID_t, reference ). They can be accessed with item_begin(), item_end() etc, and range-for loop can be obtained via items() member function: for (auto&& [ ID, value ]: data.items()) { std::cout << "data[" << ID << "] = " << value << std::endl; } (this loop has the same effect as the one in the example of the standard iterators, but it's more compact).

Detailed Description

template<typename T, typename Mapper>
class geo::GeoIDdataContainer< T, Mapper >

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

template<typename OT >

void geo::GeoIDdataContainer< T, Mapper >::resizeAs	(	geo::GeoIDdataContainer< OT, Mapper_t > const &	other,
		value_type const &	defValue
	)

Prepares the container initializing all its data.

Parameters

other	data collection to take dimensions from
defValue	the value copied to fill all entries in the container

The size of each dimension is taken by the matching one in other.

The container is sized to host data for all the elements. Each new element in the container is constructed as copy of defValue. Existing data is not touched, but it may be rearranged in a non-straightforward way.
