Validation

Package eu.beesoft.gaia.validation offers a few classes to build your own validation system.

There is a class ValidationError which instance covers one error from validation.

All ValidationError instances from one validation process are held by the instance of ValidationResult class.

The abstract superclass for all validators is class Validator. This class is initialized with message that should be made public when validation fails. And in subclasses is necessary to process method validate (Object).

There is currently just one validator implementation - NotNullValidator - which reports validation error when validated value is null.
