AtLeastOneConstructorRule (PMD Java 7.0.0 API)

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.
