  org.eclipse.soda.sat.core.framework.ProxyServiceHandlerAdapter

All Implemented Interfaces:

IProxyServiceHandler

public class ProxyServiceHandlerAdapter
extends Object
implements IProxyServiceHandler

ProxyServiceHandlerAdapter is a concrete no-op implementation of the IProxyServiceHandler interface. It is intended that this class be subclassed and one or two methods overridden. It is common for a subclass to only implement the createService() method, for example.

Method Summary

Object	createService() Create the real service Object for which a proxy was created.
void	postInvoke(Object service, Method method, Object[] args, Throwable throwable, Object data) This implementation logs throwable parameter as an error if it is not null.
Object	preInvoke(Object service, Method method, Object[] args) A hook method that is executed before the proxy has invoked the specified Method on the specified service Object.

public Object createService()

Description copied from interface: IProxyServiceHandler

Create the real service Object for which a proxy was created.

Specified by:

createService in interface IProxyServiceHandler

Returns:

The created service Object.

See Also:

IProxyServiceHandler.createService()

postInvoke

public void postInvoke(Object service,
                       Method method,
                       Object[] args,
                       Throwable throwable,
                       Object data)

This implementation logs throwable parameter as an error if it is not null.

Specified by:

postInvoke in interface IProxyServiceHandler

Parameters:

service - The service Object.

method - The Method that was invoked on the service.

args - The arguments passed to the method.

throwable - The exception thrown by the method, or null.

data - Handler specific data.

See Also:

IProxyServiceHandler.postInvoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[], java.lang.Throwable, java.lang.Object)

preInvoke

public Object preInvoke(Object service,
                        Method method,
                        Object[] args)

Description copied from interface: IProxyServiceHandler

A hook method that is executed before the proxy has invoked the specified Method on the specified service Object. The Object returned by this method is handler-specific and will be passed into the postInvoke method; for example, the current time in milliseconds could be returned as a Long, allowing the postInvoke method to calculate approximately how long the service method took to execute.

Specified by:

preInvoke in interface IProxyServiceHandler

Parameters:

service - The service Object.

method - The Method that will be invoked on the service.

args - The arguments that will be passed to the method.

Returns:

Handler specific data.
