/*

The EXPRESS ENTITY entity_instance from the SDAI_data_type_schema from

clause 10 in ISO 10303-22, shall be mapped to the C++ class Entity_instance.

The class Entity_instance shall be a subtype of the C++ class Object:

*/

class SC_DAI_EXPORT SDAI_sdaiObject {

public:

SDAI_sdaiObject();

virtual ~SDAI_sdaiObject();

// static Object_ptr _duplicate(Object_ptr);

// static Object_ptr _nil();

};

typedef SDAI_sdaiObject * SDAI_sdaiObject_ptr;

typedef SDAI_sdaiObject_ptr SDAI_sdaiObject_var;

/*

The class Object shall be accessed through the handle types Object_ptr and

Object_var. For handles to the C++ class representing a EXPRESS ENTITY data

type A, the following implicit widening operations shall be supported:

A_ptr to Object_ptr and A_var to Object_ptr. An implementation need not

support implicit widening of A_var to Object_var.

This binding shall support the following functions:

*/

//void release(Object_ptr obj);

/*

The release function indicates that the caller will no longer access the

reference obj.

*/

//Boolean is_nil(Object_ptr obj);

/*

The is_nil function shall return true if obj is a nil handle; otherwise it

returns false.

This binding does not specify that all base classes in the application

schema be virtual base classes; however, it does require that no multiply

inherited derived class contain multiple instantiations of any of its base

classes. This requirement applies to all classes, even classes used to

instantiate complex instances.
