Nested Class Summary

static interface

ValidationKit.ValidationCallback ValidationCallback is used by ValidationKit.validate() as a call back mechanism when validating a hierarchy of Validateable components.

Method Summary

static void	validate(nextapp.echo.Component c, ValidationKit.ValidationCallback validationCallback) This method will traverse the component hierarchy starting at c and find all componentsthat implement Validateable.
static boolean	validate(Validateable validateable, ValidationKit.ValidationCallback validationCallback) This method will validate a given Validateable and return true if its valid.

validate

public static void validate(nextapp.echo.Component c,
                            ValidationKit.ValidationCallback validationCallback)

This method will traverse the component hierarchy starting at c and find all componentsthat implement Validateable. It will then validate these objects via their ValidationRule.isValid() methods.

The validationCallback is then informed each time a rule fails and when a Validateable is invalid or valid.

Parameters:

c - - the component to start checking

validationCallback - -the call back interface for Validateable's

validate

public static boolean validate(Validateable validateable,
                               ValidationKit.ValidationCallback validationCallback)

This method will validate a given Validateable and return true if its valid.

The validationCallback is then informed each time a rule fails and when the Validateable is invalid or valid.

Parameters:

validateable - - the Validateable to validate

validationCallback - - the callback that will be informed

Returns:

true if the the Validateable is valid or false if not
