java.lang.Object

net.sourceforge.pmd.properties.AbstractPropertySource

net.sourceforge.pmd.lang.rule.AbstractRule

net.sourceforge.pmd.lang.java.rule.AbstractJavaRule

net.sourceforge.pmd.lang.java.rule.internal.AbstractIgnoredAnnotationRule

net.sourceforge.pmd.lang.java.rule.codestyle.AtLeastOneConstructorRule

All Implemented Interfaces:

AstVisitor, JavaVisitor, Rule, PropertySource

public class AtLeastOneConstructorRule
extends net.sourceforge.pmd.lang.java.rule.internal.AbstractIgnoredAnnotationRule

This rule detects non-static classes with no constructors; requiring even the default constructor to be explicit. It ignores classes with solely static methods, use UseUtilityClassRule to flag those.
