Interface InvokerPreprocessor

All Known Implementing Classes:

PersistableAnnotationInvokerPreprocessor, SecurityAnnotationInvokerPreprocessor

public interface InvokerPreprocessor

InvokerPreprocessor

Components implementing this interface can be plugged into AroundProcessableJAXRSInvoker, which preprocess Exchange and request object before the default JAXRSInvoker works.

For example, you may check Exchange information such as operation info in order to check some pre-conditions such as security annotation and return a custom HTTP error message instead of continuing with the default JAXRSInvoker.
