Thank you for replying, You are right, I do understand the difference between class initialization and object initialization in theory, and what I had posted was an extremely sloppy attempt made in desperation (although I acknowledge it is entirely possible I am failing to keep them separate in practice
Instead of using ".isEmpty()" I have used a try/catch, where it tries to create the coupling, and if it fails I assume it's because a ctclass's constructor is not empty. In the catch block I attempt to insert an empty class constructor on the ctclass object (so to overload the constructor) So it's like this:
String from_class = from.getName();
//Persistent Coupling
if(strength == 'P' || strength == 'p'){
try{
String toBeAdded = from_class + varname+" = new " + from_class+"();";
CtField f = CtField.make(toBeAdded, to);
to.addField(f);
}
//Hopefully this will catch cases where constructors are not empty and insert a dummy instructor
catch(Exception e){
from.makeClassInitializer();
String toBeAdded = from_class + varname+" = new " + from_class+"();";
CtField f = CtField.make(toBeAdded, to);
to.addField(f);
}
I still get a 'Exception in thread "main" javassist.CannotCompileException: [source error] no such constructor'. And as I mentioned, ideally I would like to use the getConstructors() on a ctclass to get the array of constructor objects, but this is much fuzzier in my mind. Once I have the array of constructor objects, is there a way to determine the object types? If I can loop through the array I can make a coupling with dummy variables, becasue I don't really care about the program's execution after it it coupled, only that it will compile. Something roughly like:
CtConstructor [] consts = new CtConstructor[];
ArrayList <?> results = new ArrayList<?>();
for (int i=0; i<consts.length(); i++){
if (consts[i].type == int){
results[i]=13;
else if (consts[i].type == double){
results[i] = 13.5;
}
else if (consts[i].type == char){
results[i] = 'M';
}
else if (consts[i].type == float){
results[i] = 13.5;
}
else if (consts[i].type == double){
results[i] = 13.5;
}
else if (consts[i].type == boolean){
results[i] = 13.5;
}
else{
results[i]=null;
}
}//for
}//method
