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]) < 1)
]
	[@Interface='false']

          

Example:

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