AccessorClassGeneration

AccessorClassGeneration

Instantiation by way of private constructors from outside of the constructor’s class often causes the generation of an accessor. A factory method, or non-privatization of the constructor can eliminate this situation. The generated class file is actually an interface. It gives the accessing class the ability to invoke a new hidden package scope constructor that takes the interface as a supplementary parameter. This turns a private constructor effectively into one with package scope, and is challenging to discern.
This rule is defined by the following Java class: net.sourceforge.pmd.lang.java.rule.design.AccessorClassGenerationRule
Example(s):


  
public class Outer {
 void method(){
  Inner ic = new Inner();//Causes generation of accessor class
 }
 public class Inner {
  private Inner(){}
 }
}
