public final class ClassDataAbstractionCouplingCheck

extends AbstractClassCouplingCheck

This metric measures the number of instantiations of other classes within the given class. This type of coupling is not caused by inheritance or the object oriented paradigm. Generally speaking, any abstract data type with other abstract data types as members has data abstraction coupling; therefore, if a class has a local variable that is an instantiation (object) of another class, there is data abstraction coupling. The higher the DAC, the more complex the data structure (classes) of the system.
