AtLeastOneConstructor


AtLeastOneConstructor
Each class should declare at least one constructor.
  
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
                  
//ClassOrInterfaceDeclaration[
	not(ClassOrInterfaceBody/ClassOrInterfaceBodyDeclaration/ConstructorDeclaration)
	and
	(@Static = 'false')
	and
	(count(./descendant::MethodDeclaration[@Static]) &lt; 1)
]
	[@Interface='false']

          
  
		    
		    
	    
	    
        
        
        Example:
            
                    
  
public class Foo {
 // no constructor!  not good!
}
