// ACRX_DECLARE_MEMBERS(CLASS_NAME)
//
// Use this macro to declare the member-functions "isA()", "desc()"
// and "cast()" for the class "CLASS_NAME" which is derived (at some
// level) from AcRxObject.  Declaring these functions is required for
// the class to participate in the AcRxObject runtime type identification
// mechanism.
//
// Note that you don't have to declare the class member-functions "isA()",
// "desc()" and "cast()" (i.e., this macro isn't needed) if you don't need
// to distinguish a class at runtime any further than one of its Rx-defined
// base classes.
//
// The static "rxInit()" function and the static "gpDesc" pointer, also
// declared by this macro, exist to allow us to implement the methods
// "isA()", "desc()" and "cast()".  The macros ACRX_DEFINE_MEMBERS()
// and ACRX_xxx_DEFINE_MEMBERS() allow you to define the various
// functions and static variables declared with this macro.
//
// This macro MUST BE used inside the "public" section of the class
// declaration.  For example, use it like this:
//
//     class Foo : public AcRxObject
//     {
//     public:
//         ACRX_DECLARE_MEMBERS(Foo);
//         ...etc...
//     };
//

// ACRX_DEFINE_MEMBERS(CLASS_NAME)
//
// Use this macro to define the member functions declared with
// the ACRX_DECLARE_MEMBERS() macro.
//
// This macro does not create the associated AcRxClass object; that is
// the responsibility of a service implementation, i.e., the "rxInit()"
// static member-function declared by the ACRX_DECLARE_MEMBERS() macro.
//
// The ACRX_xxx_DEFINE_MEMBERS() macros defined below use this macro,
// as well as provide alternate definitions for the "rxInit()" function.

// ACRX_NO_CONS_DEFINE_MEMBERS()
// ACRX_CONS_DEFINE_MEMBERS()
// ACRX_DXF_DEFINE_MEMBERS()
//
// These macros are similar to the ACRX_DEFINE_MEMBERS() macro,
// except they also provide implementations for the static "rxInit()"
// function.
//
// The differences between the three macros are manifested in how
// the AcRxClass object responds to AcRxClass::create() and
// AcRxClass::dxfName() member functions.
//
// ACRX_NO_CONS_DEFINE_MEMBERS(CLASS_NAME,PARENT_CLASS)
//
//       For abstract classes and desired concrete classes, for
//       which no pseudo-constructor function is associated with
//       its AcRxClass object.  For example, a class with a
//       protected/private default constructor should use
//       this macro.  <ClassName>::desc()->create()
//       returns NULL for AcRxClass objects defined this way.
//       The class has no direct DWG or DXF file representation.
//
// ACRX_CONS_DEFINE_MEMBERS(CLASS_NAME,PARENT_CLASS)
//
//       For concrete classes with a meaningful default constructor.
//       Causes <ClassName::desc()->create() to return an instance of the
//       object created with its default constructor. Causes
//       <ClassName::desc()->dxfName() to return NULL.
//
// ACRX_DXF_DEFINE_MEMBERS(CLASS_NAME,PARENT_CLASS,PROXY_FLAGS,DXF_NAME,APP)
//
//       For classes directly instantiated in DWG and DXF,
//       <ClassName::desc()->create() returns an instance of the
//       object created with its default constructor.
//       <ClassName::desc()->dxfName() defines a string that
//       the AutoCAD database queries as the preferred DXF
//       "object type" name.
//
// ACRX_STATIC_CHECK(CLASS_NAME)
//       Helper macro used by the various rxInit() implementations.
//       It makes sure that the static varible gpDesc is appropriately
//       reinitialized when necessary.
