Bug #14365
Plane geometry object hosts readout information
Description
The class geo::PlaneGeo is initialised from the geometry description (GDML), and it is meant to report geometry information on a wire plane.
Unfortunately some readout information slipped in: the signal type (fSignalType and methods).
Since this object and its relatives do not know anything about signal types, the assignment of a signal type is performed by the parent geo::TPCGeo by a guess: geo::kCollection if it is the last plane in the TPC, geo::kInduction otherwise.
This logic reflects the situation in the wire-based TPCs, but miserably fails for other types of readout (namely, dual phase where there are two collection strip planes).
This information from geo::PlaneGeo is used by geo::GeometryCore::SignalType(geo::PlaneID) to provide the signal type on a specified plane.
All code using it, or directly using geo::PlaneGeo::SignalType(), is broken with respect to these alternative detectors.
Note that queries of signal type from channel ID do not use this information, but rather forward the query to the ChannelMapAlg algorithm.
I propose the removal of this redundant and ill-designed information from geo::PlaneGeo.

Deprecated geo::PlaneGeo::SignalType() .
This is toward the resolution of issue #14365 .
Also geo::PlaneGeo::SetSignalType() is to be considered deprecated, but it's not marked so because it is still necessary to maintain the legacy, deprecated functionality.
Instead, it's being made private (it's not supposed to be used except than for post-processing during geometry initialisation).

#4 Updated by Gianluca Petrillo about 4 years ago
Non-breaking changes have been pushed into develop for the repositories: larcore, larevt, lareventdisplay, larreco and dunetpc.
Wherever geo::PlaneGeo::SygnalType() was used, now geo::GeometryCore::SignalType() provides that information.
This commit also includes the introduction of geo::PlaneGeo::ID(), geo::TPCGeo::ID() and geo::CryostatGeo::ID() to facilitate this migration and as a new feature.
