Detailed Description

The ObjectCatalog acts as a statically initialized factory. It functions in a similar manner to classic virtual factory method, except that it is no maintained list of derived objects that is required to create new objects. Instead, the ObjectCatalog creates a "catalog" of derived objects using a std::unordered_map. This std::unordered_map is then statically initialized through the declaration of a

REGISTER_CATALOG_ENTRY

#define REGISTER_CATALOG_ENTRY	(		BaseType,
			DerivedType,
			...
	)		namespace { GEOS_MAYBE_UNUSED geos::dataRepository::CatalogEntryConstructor< BaseType, DerivedType, __VA_ARGS__ > catEntry_ ## DerivedType; }

Object catalog class registration macro.

Macro that takes in the base class of the catalog, the derived class, and the argument types for the constructor of the derived class/base class, and create an object of type CatalogEntryConstructor<ClassName,BaseType,VA_ARGS> in an anonymous namespace. This should be called from the source file for the derived class, which will result in the generation of a CatalogEntry<BaseType,ClassName,...> prior to main().
