All Implemented Interfaces:

InvocationHandler

public class NioChannelDelegateInvocationHandler
extends AutoCloseableDelegateInvocationHandler

NioChannelDelegateInvocationHandler

                                           Channel delegate)

Method Detail

getChannelDelegate

public Channel getChannelDelegate()

invoke

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

Specified by:

Throws:

wrapDelegateChannel

public static <T extends Channel> T wrapDelegateChannel(Object proxyTarget,
                                                        Class<T> type,
                                                        Channel delegate)

Wraps a target instance and a Channel delegate into a proxy instance that closes both when wrapper close method called. The Channel.isOpen() call is invoked only on the delegate

Type Parameters:

T - The generic Channel wrapping interface

Parameters:

proxyTarget - The (never null) target instance - if not AutoCloseable then it's close() method will not be invoked (i.e., only the delegate)

type - The target wrapping interface

delegate - The (never null) delegate to use. Note: the delegate is closed after the target instance.

Returns:

The wrapping proxy

isQueryOpenMethodInvocation

public static boolean isQueryOpenMethodInvocation(Method m,
                                                  Object[] args)

isQueryOpenMethodInvocation

public static boolean isQueryOpenMethodInvocation(Method m)
