The lines between length and the points are dashed because it depends on the parameters as to which ones are actually accessed on a specific call.

The MOOD Metrics
The MOOD (see page 183) suite of metrics is also intended as a complete set that measures the attributes of encapsulation, inheritance, coupling, and polymorphism of a system. Let TC be the total number of classes in the system. Let Md (Ci) be the number of methods declared in a class. Consider the predicate Is_visible(Mm,i, Cj), where Mm,i is the method m in class i and Cj is the class j. This predicate is 1 if i ! j and Cj may call Mm,i. Otherwise, the predicate is 0. For example, a public method in C is visible to all other classes. A private method in C is not visible to other classes. The visibility,V(Mm,i), of a method, Mm,i, is de ned as follows:
TC X
Is_visible Mm;i ; Cj TC 1
V Mm;i
12.3.1 ENCAPSULATION
The method hiding factor (MHF) and the attribute hiding factor (AHF) attempt to measure the encapsulation.
d C PTC MP i 1 V Mm;i i 1
MHF
m 1 TC P i 1
Md Ci
AHF
d C PTC AP i 1 V Am;i i 1
m 1 TC P i 1
Ad Ci
CHAPTER 12 Object-Oriented Metrics
EXAMPLE 12.2
Calculate MHF and AHF for the following C++ code: Class A{ int a; public: void x(); void y(); }; Class B { int b; int bb; void w(); public: void z(): }; Class C { int c; void v(); }; TC = 3 method A::x() A::y() B::w() B::z() C::v() is_vis(A) 0 0 0 1 0 is_vis(B) 1 1 0 0 0 is_vis(C) 1 1 0 1 0 V(Mm,i) 1 1 0 1 0
MHF = 2/5 = 0.4 attribute A::a() B::b() B::bb() C::c() is_vis(A) 0 0 0 0 is_vis(B) 0 0 0 0 is_vis(C) 0 0 0 0 V(Am,i) 0 0 0 0
AHF = 4/4 = 1.0
Object-Oriented Metrics
12.3.2 INHERITANCE FACTORS
There are two measures of the inheritance, the method inheritance factor (MIF) and the attribute inheritance factor (AIF). Md Ci Number of methods declared in a class i Mi Ci Number of methods inherited (and not overridden) in a class i Ma Ci Md Ci Mi Ci Number of methods that can be invoked in association with class i
TC X
Mi Ci Ma Ci
MIF
i 1 TC X i 1
Ad Ci Number of attributes declared in a class i Ai Ci Number of attributes from base classes that are accessible in a class i Aa Ci Ad Ci Ai Ci Number of attributes that can be accessed in association with class i
TC X
Ai Ci Aa Ci
AIF
i 1 TC X i 1
EXAMPLE 12.3
Calculate MIF and AIF from the following C++ code: Class A{ protected: int a; public: void x(); virtual void y(); }; Class B public A { int b; protected: int bb; public: void z(): void y(); void w(); }; Class C public B { int c; void v(); };

COUPLING FACTOR
The coupling factor (CF) measures the coupling between classes excluding coupling due to inheritance. Let is_client(ci ,cj 1 if class i has a relation with class j; otherwise, it is zero. The relation might be that class i calls a method in class j or has a reference to class j or to an attribute in class j. This relationship cannot be inheritance.
