Medição
Counts how far down in the inheritance hierarchy a class or aspect is
declared.
Lack of Cohesion in
Operations (LCOO)
Measures the lack of cohesion of a class or an aspect in terms of the
amount of method and advice pairs that do not access the same instance
variable.
Lines of Code (LOC)
Number of Attributes (NOA)
Weighted Operations per
Component (WOC)
Counts the lines of code.
Counts the number of attributes of each class or aspect.
Counts the number of methods and advices of each class or aspect and the
number of its parameters.

Definition
Counts the number of classes and aspects whose main purpose is to
contribute to the implementation of a concern and the number of other
classes and aspects that access them.
Counts the number of methods and advices whose main purpose is to
contribute to the implementation of a concern and the number of other
methods and advices that access them.
Counts the number of transition points through lines of code. A transition
point is a place in the code where there is a “concern switch”.
Counts the number of other classes and aspects to which a class or an
aspect is coupled.
