All Known Implementing Classes:

CachedRuleViolation, ParametricRuleViolation
```
public interface RuleViolation
```
A RuleViolation is created by a Rule when it identifies a violation of the Rule constraints. RuleViolations are simple data holders that are collected into a Report.
Since PMD 6.21.0, implementations of this interface are considered internal API and hence deprecated. Clients should exclusively use this interface.
