Interface ValidationTransformer<T extends Throwable>

Type Parameters:

T - type of Throwable

All Superinterfaces:

org.apache.commons.collections.Transformer

public interface ValidationTransformer<T extends Throwable>
extends org.apache.commons.collections.Transformer

By default Transformer does not allow throwing of Throwable. For validation exception is the default manner. So provide a wrapper impl that supports throwing expected validation exception of type T

The Transformer.transform(Object) is expected to throw either

• A RuntimeException that wraps the actual exception in Throwable.getCause()
• A runtime exception with no Throwable.getCause(), main exception is itself of type T

Example usage: validateTransformer.validate(request);
