Detailed Description

The HGTD_LayerBuilderCond parses the senstive detector elments and orders them onto a Disc surface; no cylindrical layers are expected. This implementation is based on what done in the SiLayerBuilderCond, adapted to the HGTD use case.

inlineinherited

Declare a new Gaudi property.

Parameters

name	Name of the property.
property	Object holding the property value.
doc	Documentation string for the property.

This is the generic version, for types that do not derive from SG::VarHandleKey. It just forwards to the base class version of declareProperty.

Parameters
