org.apache.sshd.common.util.closeable.AutoCloseableDelegateInvocationHandler

org.apache.sshd.common.util.closeable.NioChannelDelegateInvocationHandler

All Implemented Interfaces:

java.lang.reflect.InvocationHandler

public class NioChannelDelegateInvocationHandler
extends AutoCloseableDelegateInvocationHandler

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

Method Detail

getChannelDelegate

public java.nio.channels.Channel getChannelDelegate()

invoke

public java.lang.Object invoke(java.lang.Object proxy,
                               java.lang.reflect.Method method,
                               java.lang.Object[] args)
                        throws java.lang.Throwable

Specified by:

invoke in interface java.lang.reflect.InvocationHandler

Overrides:

invoke in class AutoCloseableDelegateInvocationHandler

Throws:

java.lang.Throwable

wrapDelegateChannel

public static <T extends java.nio.channels.Channel> T wrapDelegateChannel(java.lang.Object proxyTarget,
                                                                          java.lang.Class<T> type,
                                                                          java.nio.channels.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
