Affects PMD Version:
6.20.0
Rule:
LawOfDemeter
Description:
LawOfDemeter does not recognise 'this' pointer and includes its dot accessor as a count towards method chaining. It must not. Similarly for 'super' while calling parent class functions.
Code Sample demonstrating the issue:
package pmdtests;
public class Foo {
private final int i;
public Foo(int i) {
this.i = i;
}
public void meth() {
System.out.println(this.i); // wrong violation: method chain calls
System.out.println(super.i); // wrong violation: method chain calls
System.out.println(i); // no violation
}
public void method(Foo this) {
System.out.println(this.i); // wrong violation: method chain calls
}
public void method(Foo this, String... args) {
System.out.println(this.i); // wrong violation: method chain calls
for (String arg: args)
System.out.println(arg);
}
}
