I am using the Reflection API to calculate the afferent and efferent couplings of a class and in turn calculate the Stability metric of each class. Then adding the results to a HashMap. The program seems to run correctly when I run the debugger, and it seems to pass the correct values to the HashMap.
When I check the return statement of the method (which is the map) the Key is correct (Key is a class), the value (Value is the measure object) is incorrect. The value is always the result for one of the interfaces.
When the Map returns after calculation it has the correct key, but the value associated with each key is incorrect. The value is the same for each Key
public ClassMap getEfferent(ClassList list){
map = new ClassMap();
measure = new Measurement();
//cycle through the list
for (int i = 0; i < list.size(); i++) {
//Get the class needed for efferent inspection
Class cla = list.getMyClass(i);
//get the interfaces from the class
Class[] interfaces = cla.getInterfaces();
//if the class implements any interfaces increment efferent
for(Class inter : interfaces){
//if the interface is part of the list
if(list.contains(inter)){
efferentCoupling++;
}
}//end interfaces
Constructor[] cons = cla.getConstructors();
Class[] conParams;
for(Constructor c: cons){
conParams = c.getParameterTypes();
for(Class par: conParams){
//if the paramater name is on the list of classes ++
if(list.contains(par.getName())){
efferentCoupling ++;
}
}
}//end Constructor params
Field[] fields = cla.getFields();
for(Field fie: fields ){
//if the field name is on the list of classes ++
if(list.contains(fie.getName()))
efferentCoupling ++;
}//fields
//get the methods for the class
Method[] classMethods = cla.getMethods();
Class[] params;
//
for(Method meth: classMethods){
Class returnTypes = meth.getReturnType();
if(list.contains(meth.getReturnType().getName())){
efferentCoupling ++;
}
}
//pass in the list and the class name to check for afferent coupling
//return the afferent score as an interger
afferentCoupling = getAfferent(list, cla.getName());
Name = cla.getName();
//pass the the class name into setClassName
measure.setClassName(Name);
//pass in the efferentCoupling for the class
measure.setEfferentCoupling(efferentCoupling);
//pass in the afferentCoupling for the class
measure.setAfferentCoupling(afferentCoupling);
//System.out.println(measure.getStability());
cla = list.getMyClass(i);
//put the class(key) measure (value)
map.put(cla, measure);
}//end for
//resets efferent coupling
efferentCoupling = 0;
return map;
}//getAfferent
//method passes in the ClassList and the class name to be checked
public int getAfferent(ClassList list, String name){
int afferent = 0;
for (int i = 0; i < list.size(); i++) {
//Get the class needed for afferent inspection
Class cla = list.getMyClass(i);
Class[] interfaces = cla.getInterfaces();
//if the class implements any interfaces increment efferent
for(Class inter : interfaces){
//if the interface name is same as inter.getName() then increment afferent
if(inter.getName() == name){
afferent ++;
}
}//end interfaces
Constructor[] cons = cla.getConstructors();
Class[] conParams;
for(Constructor c: cons) {
conParams = c.getParameterTypes();
for (Class par : conParams) {
//if constructor params == name then increment
if (par.getName() == name) {
afferent++;
}
}
}
Field[] fields = cla.getFields();
for(Field fie: fields ){
if(fie.getName() == name)
afferent++;
}//fields
Method[] classMethods = cla.getMethods();
Class[] params;
for(Method meth: classMethods){
Class returnTypes = meth.getReturnType();
if(meth.getReturnType().getName() == name){
afferent ++;
}
}
}
return afferent;
}
Any help would be great.
