Detailed Description

template<typename GEOID>
class geo::details::TPC_id_iterator_base< GEOID >

Base forward iterator browsing all TPC IDs in the detector.

Template Parameters

GEOID

ID type to be used

This iterator requires that GEOID is derived from geo::TPCID. Note that no polymorphic behaviour is required, or expected, from GEOID.

This iterator is designed to carry on, untouched, anything else that the GEOID type defines beyond the required TPCID data.

Note

A number of "local" methods are overloaded: since there is no polymorphism here and they are not virtual functions, these are designed not to replace the inherited methods except within the non-inherited and explicitly redefined methods.

Currently, backward iterations are not supported.
