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

Implements java.lang.reflect.InvocationHandler.invoke.

Doc from java.lang.reflect.InvocationHandler.invoke.

Processes a method invocation on a proxy instance and returns the result. This method will be invoked on an invocation handler when a method is invoked on a proxy instance that it is associated with.

Parameters
proxy:Object

the proxy instance that the method was invoked on

method:Method

the Method instance corresponding to the interface method invoked on the proxy instance. The declaring class of the Method object will be the interface that the method was declared in, which may be a superinterface of the proxy interface that the proxy class inherits the method through.

args:Object[]

an array of objects containing the values of the arguments passed in the method invocation on the proxy instance, or null if interface method takes no arguments. Arguments of primitive types are wrapped in instances of the appropriate primitive wrapper class, such as java.lang.Integer or java.lang.Boolean.

Returns:Object

the value to return from the method invocation on the proxy instance. If the declared return type of the interface method is a primitive type, then the value returned by this method must be an instance of the corresponding primitive wrapper class; otherwise, it must be a type assignable to the declared return type. If the value returned by this method is null and the interface method's return type is primitive, then a NullPointerException will be thrown by the method invocation on the proxy instance. If the value returned by this method is otherwise not compatible with the interface method's declared return type as described above, a ClassCastException will be thrown by the method invocation on the proxy instance.

Annotations
@Override
Exceptions
Throwable:
the exception to throw from the method invocation on the proxy instance. The exception's type must be assignable either to any of the exception types declared in the throws clause of the interface method or to the unchecked exception types java.lang.RuntimeException or java.lang.Error. If a checked exception is thrown by this method that is not assignable to any of the exception types declared in the throws clause of the interface method, then an UndeclaredThrowableException containing the exception that was thrown by this method will be thrown by the method invocation on the proxy instance.

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

Parameters
<T>
The generic Channel wrapping interface
proxyTarget:Object

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

type:Class<T>

The target wrapping interface

delegate:Channel

The (never null) delegate to use

Note

the delegate is closed after the target instance.

Returns:T

The wrapping proxy
