UnnecessaryConstructor


UnnecessaryConstructor
This rule detects when a constructor is not necessary; i.e., when there's only one constructor,
it's public, has an empty body, and takes no arguments.
      
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
                        
//ClassOrInterfaceBody[count(ClassOrInterfaceBodyDeclaration/ConstructorDeclaration)=1]
/ClassOrInterfaceBodyDeclaration/ConstructorDeclaration
[@Public='true']
[not(FormalParameters/*)]
[not(BlockStatement)]
[not(NameList)]
[count(ExplicitConstructorInvocation/Arguments/ArgumentList/Expression)=0]
                    
                
  
		    
		    
	    
	    
        
        
        Example:
            
                    
  
public class Foo {
 public Foo() {}
}
