Field Detail

remoteInvoker

protected Invoker remoteInvoker

Invoker to the remote JMX node.

---

localInvoker

protected static Invoker localInvoker

Static references to local invokers.

Constructor Detail

InvokerInterceptor

public InvokerInterceptor()

Exposed for externalization.

Method Detail

getLocal

public static Invoker getLocal()

Get the local invoker reference, useful for optimization.

---

setLocal

public static void setLocal(Invoker invoker)

Set the local invoker reference, useful for optimization.

---

isLocal

public boolean isLocal()

Returns wether we are local to the originating container or not.

---

isLocal

public boolean isLocal(Invocation invocation)

Whether the target is local

Parameters:

invocation - the invocation

Returns:

true when the target is local

---

invoke

public Object invoke(Invocation invocation)
              throws Exception

The invocation on the delegate, calls the right invoker. Remote if we are remote, local if we are local.

Specified by:

invoke in class Interceptor

Throws:

Exception

---

invokeLocal

protected Object invokeLocal(Invocation invocation)
                      throws Exception

Invoke using local invoker

Parameters:

invocation - the invocation

Returns:

the result

Throws:

Exception - for any error

---

invokeMarshalled

protected Object invokeMarshalled(Invocation invocation)
                           throws Exception

Invoke using local invoker and marshalled

Parameters:

invocation - the invocation

Returns:

the result

Throws:

Exception - for any error

---

invokeInvoker

protected Object invokeInvoker(Invocation invocation)
                        throws Exception

Invoke using invoker

Parameters:

invocation - the invocation

Returns:

the result

Throws:

Exception - for any error

---

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Externalize this instance.

If this instance lives in a different VM than its container invoker, the remote interface of the container invoker is not externalized.

Specified by:

writeExternal in interface Externalizable

Overrides:

writeExternal in class Interceptor

Throws:

IOException

---

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
                         ClassNotFoundException

Un-externalize this instance.

We check timestamps of the interfaces to see if the instance is in the original VM of creation

Specified by:

readExternal in interface Externalizable

Overrides:

readExternal in class Interceptor

Throws:

IOException

ClassNotFoundException
