OVal
OVal is a pragmatic and extensible general purpose validation framework for any kind of Java objects (not only JavaBeans) and allows you:
* to easily validate objects on demand,
* to specify constraints for class fields and getter methods,
* to validate objects based on certain EJB3 JPA annotations (namely all field annotations that require a not-null value),
* to configure constraints via annotations, POJOs and/or simple XML files,
* to express constraints using scripting languages such as Groovy, BeanShell, and JavaScript
* to easily create custom constraints, and
* to develop new constraint configuration mechanisms
When using AspectJ certain programming by contract (aka Design By Contract or DBC) these features are available:
* specifying constraints for constructor parameters that are automatically checked when a constructor is called (preconditions),
* specifying constraints for method parameters that are automatically checked when a method is called (preconditions),
* requiring a certain object state before a method is called (preconditions)
* enforcing object validation after an object has been created (invariants),
* enforcing object validation before/after a method of an object is/has been called (invariants),
* specifying constrains for a method's return value that are automatically checked after a method has been executed (postconditions),
* requiring a certain object state after a method is called (postconditions).
