Migration Notes (1.0 to 1.10)

• net.sf.oval.exception.ConstraintsViolatedException was moved from package net.sf.oval.guard

• net.sf.oval.exception.ExceptionTranslatorJDKExceptionsImpl was moved from package net.sf.oval.guard
• @AssertTrue, @AssertFalse are now evaluating the String representation of a value if it is not of type Boolean/boolean

New Features

• New constraint @NotBlank

Migration Notes (0.9 to 1.0)

• Validator.setMessageResolver and Validator.getMessageResolver are now static, this means the same message resolver instance is used with all Validator/Guard instances.
• Class net.sf.oval.collection.CollectionFactoryHolder has been moved to package net.sf.oval.internal. This class should not be used directly, the collection factory in use can be retrieved via the static method Validator.getCollectionFactory and set with the static method Validator.setCollectionFactory.
• @Guarded.applyFieldConstraintsToSetter has been renamed to @Guarded.applyFieldConstraintsToSetters
• JPAAnnotationsConfigurer constraint mappings extended:
  @javax.persistence.OneToOne => @net.sf.oval.constraints.AssertValid
  @javax.persistence.OneToMany => @net.sf.oval.constraints.AssertValid
  @javax.persistence.ManyToOne => @net.sf.oval.constraints.AssertValid

New Features

• Scripting Support (Groovy, JavaScript, BeanShell) for class invariants, Pre- and Postconditions (@Assert, @Pre, @Post)
• Automatic check of class invariants on calls to all non-private methods
• Check of class invariants, pre-, postconditions can be separately enabled or disabled during runtime
• New constraints: @CheckWith, @Future, @HasSubstring, @Max, @MaxLength, @MaxSize, @Min, @MinLength, @MinSize, @Past
• validating/guarding of static fields and methods is now supported
• introduced the concept of constraint profiles
• added Guard.setExceptionTranslator() allowing you to change the type of exception that is thrown on constraint violations

Migration Notes (0.8 to 0.9)

In the attempt to add all the new features and to make OVal 1.0 release ready, a large part of OVal's code base has been refactored.

This led to certain changes in the API:

• Packages with names in plural have been changed to singular (e.g. net.sf.oval.constraints => net.sf.oval.constraint)
• Everything related to programming by contract has been moved into a new package called net.sf.oval.guard. This includes ConstraintsViolatedListener, GuardAspect, Guard, @PreValidateThis, @PostValidateThis and others.
• The Guard class now extends the Validator class, therefore the Guard.getValidator() method has been removed.
• For class invariants are now checked by default for guarded classes on every call to non-private methods. If you require the old behaviour you can disable automatic invariant checking via MyGuardAspect.aspectOf().getGuard().setInvariantCheckingActivated(false)
• Getter methods now need to be annotated with @IsInvariant if their return value should be checked on a object validation via Validator.validate(Object)
• The Guard's setReportingMode() methods have been replaced with setInProbeMode methods.
