Namespaces
namespace	gsystem

Variables
constexpr char	gsystem::GMIRRORSKINSURFACE [] = "SkinSurface"
	Border value marking an optical surface applied to the whole volume skin.
constexpr char	gsystem::GSYSTEMCOMPONENTMATERIAL [] = "Component"
Database row sizes
Expected number of positional fields for serialized DB/ASCII rows. The module reads geometry and material data as serialized, positional vectors. These constants define the expected number of fields for each record type.
constexpr int	gsystem::GVOLUMENUMBEROFPARS = 22
constexpr int	gsystem::GVOLUMELEGACYNUMBEROFPARS = 21
	Number of database parameters defining a legacy gvolume entry without g4placement_type.
constexpr int	gsystem::GMATERIALNUMBEROFPARS = 18
	Number of database parameters defining a gmaterial entry.
constexpr int	gsystem::GMIRRORNUMBEROFPARS = 16
	Number of database parameters defining a gmirror entry.
Default placement strings
Default position and rotation strings, primarily for the ROOT/world volume. These are used when creating the implicit ROOT/world volume or when a configuration requests a default placement. Units are embedded in the strings and interpreted by the same utilities used by geometry parsing.
constexpr char	gsystem::DEFAULTPOSITION [] = "0*cm, 0*cm, 0*cm"
constexpr char	gsystem::DEFAULTROTATION [] = "0*deg, 0*deg, 0*deg"
constexpr char	gsystem::DEFAULTG4PLACEMENTTYPE [] = "active"
Error codes
Module-level exit/status codes. Values are in the 200s range and are used by the logger error path to provide stable identifiers for common failure modes.
constexpr int	gsystem::ERR_GVOLUMEALREADYPRESENT = 201
constexpr int	gsystem::ERR_GWRONGNUMBEROFPARS = 202
constexpr int	gsystem::ERR_GSETUPFILENOTOFOUND = 203
constexpr int	gsystem::ERR_GVOLUMENOTFOUND = 204
constexpr int	gsystem::ERR_GDIRNOTFOUND = 205
constexpr int	gsystem::ERR_GMATERIALOPTICALPROPERTYMISMATCH = 206
constexpr int	gsystem::ERR_GMATERIALNOTFOUND = 207
constexpr int	gsystem::ERR_GVOLUMENAMECONTAINSINVALID = 208
constexpr int	gsystem::ERR_GSQLITEERROR = 209
constexpr int	gsystem::ERR_GMATERIALALREADYPRESENT = 210
constexpr int	gsystem::ERR_EXPERIMENTNOTFOUND = 211
constexpr int	gsystem::ERR_G4PLACEMENTTYPE = 212
constexpr int	gsystem::ERR_GMIRRORALREADYPRESENT = 213
constexpr int	gsystem::ERR_GMIRRORNOTFOUND = 214
constexpr int	gsystem::ERR_GMIRRORINVALID = 215
Environment and naming conventions
Shared names used across factories and core types.
constexpr char	gsystem::GEMCDB_ENV [] = "GEMCDB_ENV"
constexpr char	gsystem::ROOTWORLDGVOLUMENAME [] = "root"
	Canonical name for the ROOT/world gvolume entry.
constexpr char	gsystem::ROOTDEFINITION [] = "G4Box 15*m 15*m 15*m G4_AIR"
constexpr char	gsystem::MOTHEROFUSALL [] = "akasha"
	Special mother-name marker for the top-level world root.
constexpr char	gsystem::GSYSTEM_DELIMITER [] = "/"
	Delimiter used to build fully-qualified names (system/name).
Factory labels
Identifiers used in configuration to select concrete factories.
constexpr char	gsystem::GSYSTEMASCIIFACTORYLABEL [] = "ascii"
constexpr char	gsystem::GSYSTEMCADTFACTORYLABEL [] = "CAD"
constexpr char	gsystem::GSYSTEMGDMLTFACTORYLABEL [] = "GDML"
constexpr char	gsystem::GSYSTEMMYSQLTFACTORYLABEL [] = "mysql"
constexpr char	gsystem::GSYSTEMSQLITETFACTORYLABEL [] = "sqlite"
constexpr char	gsystem::GSYSTEMSQLITETDEFAULTFILE [] = "gemc.db"
	Default sqlite DB filename used when the user does not specify one.
constexpr char	gsystem::GSYSTEMSASCIISEARCHDIR [] = "."
	Default search directory for ASCII factory files.

Detailed Description

This header centralizes:

• geometry/material row sizes used by database-backed factories;
• default placement/rotation strings for ROOT/world volumes;
• common error codes used by geometry/material loaders;
• factory labels and naming conventions.

Assumptions:

• Volumes and materials in each system must have a unique name.
