OVal is a generic Java 5 based object validation framework that uses annotations to express constraints and AspectJ to handle automatic validation (programming by contract).
OVal allows you to:
- to specify constraints for class fields and method return values
- to easily validate objects on demand
- to specify constraints for constructor parameters that are automatically checked when the constructor is called
- to specify constraints for method parameters that are automatically checked when the method is called
- to enforce full object validation after an object instance has been created
- to enforce full object validation before a method of the object is called
- to enforce full object validation after a method of the object is called
- to either let OVal throw constraint violation exceptions during automatic checks or alternatively notify constraint violation listeners.
- to easily create custom constraints
