iScreen

This package contains classes and interfaces that are considered "public" to applications that are using this framework. This means that applications using this framework only need to import this package.

The ValidationService interface defines the primary entry point into the iScreen validation framework. It's validate() and validateObject() methods executes all appropriate validators that are represented by the service. An instance of the service represents a "Validation Set" defined in a configuration file.

The ValidationException (ObjectValidationException) is thrown when a failure is found (or a warning). From it, individual ValidationFailure objects can be retrieved (or just the messages, themselves, as String objects). The ValidationFailure objects contain information about the service, Validator, and context in which a failure occurs.

This package contains classes and interfaces that provide implementation details for the framework. Typically, an application developer does not need to deal with these classes directly.

This package represents the heart of the framework implementation, so if an application developer needs to understand the guts of iScreen, this is the package to see. Of particular note is the ContextBean object, which represents the base root used by both OGNL and MVEL. In addition, resource (for internationalization support) objects, and validator handling code is contained within this package.

This package contains the XML-specific parsing and implementation details associated with that parsing. Typically, an application developer does not need to deal with these classes directly.

This package contains classes that implement the org.iscreen.Validator interface and are used for validating individual fields (or a set of fields). Typically, they subclass the org.iscreen.BaseValidator abstract class.

These classes provide standard business logic to ensure that Java object fields/properties are "correct" (meaning, they are valid based upon some configured business requirements).
