public static void validate(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

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
