Interface FieldSetValidator

All Superinterfaces:

java.io.Serializable

public interface FieldSetValidator

extends java.io.Serializable

This interface defines a mechanism for the validation of an arbitrary set of fields on a form. This is mostly used for an atomic validation operation on more than one field in the form. The main uses of this would be things like making sure that there was a state selected if the country was USA, Australia or Canada or making sure that the sum of the net and the tax was the total of an order form.
