#define SB_DECLARE_BASE_TYPE	(		DERIVED_TYPE,
			BASE_TYPE
	)

Parameters

DERIVED_TYPE	The derived registered type
BASE_TYPE	The base registered type

This macro registers a base type in a SAMSON Element.

Assume for example a SAMSON Element contains the following classes:

class A {

SB_CLASS

public:
    
    A() {}
    virtual ~A() {}
    
};

SB_REGISTER_TYPE(A, "A", "BF99103E-06FE-C4C1-D929-4C6E833B101C");

class B : public A {

SB_CLASS

public:
    
    B() {}
    virtual ~B() {}
    
};

SB_REGISTER_TYPE(B, "B", "D67D0F1A-540D-052F-CC31-2122E0089669");

SB_DECLARE_BASE_TYPE(B, A);

The SB_DECLARE_BASE_TYPE macro declares to SAMSON's introspection mechanism that class B derives from class A.

Both the derived and the base types should be registered through either SB_REGISTER_TYPE or SB_REGISTER_TARGET_TYPE (whichever is appropriate).

Note that, at the moment, SAMSON's introspection mechanism may not expose multiple inheritance relationships: while it is perfectly possible to expose a class that inherits multiple classes, the SB_DECLARE_BASE_TYPE macro may be used to expose only one derivation relationship, with only one of the base classes.
