i tried to get the inherited methods and fields from java source code but i have this problem :
i tried to find inherited methods and fields from each class in my file which contained java code source , the syntax is correct but i have some errors when executing the program
cu.accept(new VoidVisitorAdapter<Void>() {
public void visit(ClassOrInterfaceDeclaration cid, Void arg) {
super.visit(cid, arg);
cid.resolve().getAllFields().stream().forEach(af -> {
nmbre_attribus++;
});
cid.resolve().getDeclaredFields().stream().forEach(df -> {
Nmbre_attributs_déclarées++;
});
cid.resolve().getAllMethods().stream().forEach(am -> {
nmbre_methds++;
});
cid.resolve().getDeclaredMethods().stream().forEach(dm -> {
Nmbre_methodes_déclarées++;
});
}
}, null);
when i compile the whole code i have the following errors :
Exception in thread "main" java.lang.IllegalStateException: No data of this type found. Use containsData to check for this first.
