Detailed Description

template<typename Cont, typename Mapping>
class phot::OpDetVisibilityData< Cont, Mapping >

A container for photon visibility mapping data.

This container is designed to replace the use of plain pointers to library data, adding an intermediate mapping layer.

A proper mapping allows to use symmetries of the detector to reduce the redundant size of the library, at the cost of some run time.

This container is used as a util::MappedContainer object, with the addition of being aware of whether the contained data is valid or not. The validity is estimated by considering the original data that is being mapped, that is the data from the library. If the data is invalid or empty, as it may be for a null pointer or an empty vector, the container data is also considered to be invalid.

Implementation notes

In the current implementation, the concept of data being invalid is implemented by forcing the nominal size of the container to be zero.

Known limitations

Currently the mapping of the optical detectors is forced to be a static collection of detector IDs. If more flexibility is needed, the design of the container internals need to be updated to allow run time polymorphism.

Given the type of validity detection described above, it takes extra steps to provide a default mapping for areas not covered by the library. While with plain util::MappedContainer that can be achieved by a empty data container and a mapping returning InvalidIndex for all optical detectors, here this would just yield to an invalid container. Instead, together with that mapping, some fake data needs to be supplied to phot::OpDetVisibilityData, which will be basically ignored and may be of any size larger than zero (or more precisely, phot::isValidLibraryData() must return false).

Constructor & Destructor Documentation

template<typename Cont, typename Mapping>
phot::OpDetVisibilityData< Cont, Mapping >::OpDetVisibilityData ( DataContainer_t const &  cont,
Mapping_t const &  mapping,
size_type  size,
value_type  defValue 
)
inline

Constructor: acquires data, mapping and a default value.

Parameters
contcontainer with the data to be mapped
mappingthe mapping to be used
sizethe size of the container after mapping
defValuevalue to be used as default
See Also
MappedContainer(DataContainer_t const&, Mapping_t const&, size_type, value_type)

This works as the equivalent util::MappedContainer constructor, except that if the data in cont is deemed invalid the size is overridden to zero.

Constructor: acquires data and mapping.

Parameters
contcontainer with the data to be mapped
mappingthe mapping to be used
See Also
util::MappedContainer(DataContainer_t const&, Mapping_t const&, size_type)

The size of the container is declared to be the minimal one (see minimal_size()), unless data of the library cont is invalid, in which case the full container is invalid.

The default value is assigned as in util::MappedContainer(DataContainer_t const&, Mapping_t const&, size_type).
