public Interface IDataProviderInterceptor

extends ITestNGListener
Imports
java.util.Iterator
This interface helps define an interceptor for data providers. Implementations of this TestNG listener can be wired in via the @Listeners annotation or via the listeners tag in the suite file or via a Service Provider Interface mechanism.

The implementation would be able to alter the actual set of data using which a test method would be iterated upon.
