public class ClassMetrics
extends java.lang.Object

Store details needed for calculating a class's Chidamber-Kemerer metrics. Most fields in this class are set by ClassVisitor. This class also encapsulates some policy decision regarding metrics measurement.

getNoc

public int getNoc()

Return the number of children

setRfc

public void setRfc(int r)

Increment the Response for a Class

getRfc

public int getRfc()

Return the Response for a Class

setDit

public void setDit(int d)

public int getLcom()

Return the class's lack of cohesion in methods metric

setLcom

public void setLcom(int l)

Set the class's lack of cohesion in methods metric

getCa

public int getCa()

Return the class's afferent couplings metric

addAfferentCoupling

public void addAfferentCoupling(java.lang.String name)

Add a class to the set of classes that depend on this class

incNpm

public void incNpm()

Increment the number of public methods count

getNpm

public int getNpm()

Return the number of public methods metric

isPublic

public boolean isPublic()

Return true if the class is public

setPublic

public void setPublic()

Call to set the class as public

isJdkClass

public static boolean isJdkClass(java.lang.String s)

Return true if the class name is part of the Java SDK

toString

public java.lang.String toString()

Return the 6 CK metrics plus Ce as a space-separated string

Overrides:

toString in class java.lang.Object

setVisited

public void setVisited()

Mark the instance as visited by the metrics analyzer

isVisited

public boolean isVisited()

Return true if the class has been visited by the metrics analyzer. Classes may appear in the collection as a result of some kind of coupling. However, unless they are visited and analyzed, we do not want them to appear in the output results.
