Interface CompositeProxy.InvokeTunnel

Enclosing class:

CompositeProxy

public static interface CompositeProxy.InvokeTunnel

Invocation tunnel. Must be used when building a composite proxy from objects that implement package-private interfaces to prevent IllegalAccessException exceptions being thrown by Proxy instances. Must be implemented by classes from packages with package-private interfaces used with CompositeProxy class. Assumed implementation: invalid input: '{@snippet : package org.foo; import java.lang.reflect.InvocationHandler; import java.lang.reflect.Method; import jdk.jpackage.internal.util.CompositeProxy; final class CompositeProxyTunnel implements CompositeProxy.InvokeTunnel { @Override public Object invoke(Object obj, Method method, Object[] args) throws Throwable { return method.invoke(obj, args); } @Override public Object invokeDefault(Object proxy, Method method, Object[] args) throws Throwable { return InvocationHandler.invokeDefault(proxy, method, args); } static final CompositeProxyTunnel INSTANCE = new CompositeProxyTunnel(); }'

Method Summary

Modifier and Type	Method	Description
Object	invoke(Object obj, Method method, Object[] args)	Processes a method invocation on an object of composite proxy and returns the result.
Object	invokeDefault(Object proxy, Method method, Object[] args)	Processes a default interface method invocation on a composite proxy and returns the result.

Method Details

invoke

Object invoke(Object obj,
 Method method,
 Object[] args)
       throws Throwable

Processes a method invocation on an object of composite proxy and returns the result.

Parameters:

obj - the object on which to invoke the method

method - the method to invoke

args - the arguments to use in the method call

Returns:

the result of the method call

Throws:

Throwable - if the method throws

Implementation Note:

Implementation should call the given method on the given object with the given arguments and return the result of the call.

invokeDefault

Object invokeDefault(Object proxy,
 Method method,
 Object[] args)
              throws Throwable

Processes a default interface method invocation on a composite proxy and returns the result.

Parameters:

proxy - the proxy parameter for InvocationHandler.invokeDefault(Object, Method, Object...) call

method - the method parameter for InvocationHandler.invokeDefault(Object, Method, Object...) call

args - the args parameter for InvocationHandler.invokeDefault(Object, Method, Object...) call

Returns:

the result of the InvocationHandler.invokeDefault(Object, Method, Object...) call

Throws:

Throwable - if the InvocationHandler.invokeDefault(Object, Method, Object...) call throws

Implementation Note:

Implementation should call InvocationHandler.invokeDefault(Object, Method, Object...) method on the given proxy object with the given arguments and return the result of the call.
