public final class AdapterProxyFactoryHelper
extends java.lang.Object

Utility class to create a proxy object around a service implementation, in order to catch any exception thrown by the implementation and throw another exception, according to application developer-supplied rules.

As a matter of fact, such proxy creation also enables to make a POJO service implementation with no service interface usable by Hivemind, by just creating an interface with all public methods of the POJO.

createProxy

public static java.lang.Object createProxy(java.lang.Class serviceInterface,
                                           java.lang.Object service,
                                           java.util.Map methodsMapping,
                                           ExceptionMapper exceptionMapper)

Creates a proxy of type serviceInterface, wrapping service implementation class, and translating any exception thrown by service into another exception through mapper.

Parameters:

serviceInterface - the interface that the proxy must implement; service does not have to implement that interface or any interface at all.

service - the actual service implementation class to be proxied

methodsMapping - a map from serviceInterface methods to service methods to be used to perform the method mapping from one class to the other

exceptionMapper - the instance to perform the mappping of any thrown Throwable into another one.

Returns:

the proxied service that implements serviceInterface and delegates calls to service
