InvokerInterceptor
public class InvokerInterceptor extends Interceptor implements Externalizable(Code)
A very simple implementation of it that branches to the local stuff.
author:

author:
   Scott.Stark@jboss.org
version:
   $Revision: 57209 $

Field Summary
protected static Class invokerProxyHA

protected static Invoker localInvoker
     Static references to local invokers.
protected Invoker remoteInvoker
     Invoker to the remote JMX node.
final static SafeClone safeToReuse


Constructor Summary
public InvokerInterceptor()
     Exposed for externalization.

Method Summary
protected IMarshalledValue createMarshalledValueForCallByValue(Object value)

public static Invoker getLocal()
     Get the local invoker reference, useful for optimization.
public boolean hasLocalTarget(Invocation invocation)

public Object invoke(Invocation invocation)
     The invocation on the delegate, calls the right invoker.
protected Object invokeInvoker(Invocation invocation)

protected Object invokeLocal(Invocation invocation)

protected Object invokeLocalMarshalled(Invocation invocation)

protected Object invokeMarshalled(Invocation invocation)

public boolean isClustered(Invocation invocation)
     Whether we are in a clustered environment
NOTE: This should be future compatible under any new design where a prior target chooser interceptor picks a non HA target than that code being inside a ha invoker.
public boolean isLocal()
     Returns wether we are local to the originating container or not.
public boolean isLocal(Invocation invocation)

public void readExternal(ObjectInput in)
     Un-externalize this instance.
public static void setLocal(Invoker invoker)
     Set the local invoker reference, useful for optimization.
public void writeExternal(ObjectOutput out)
     Externalize this instance.

Field Detail
invokerProxyHA
protected static Class invokerProxyHA(Code)
The InvokerProxyHA class

localInvoker
protected static Invoker localInvoker(Code)
Static references to local invokers.

remoteInvoker
protected Invoker remoteInvoker(Code)
Invoker to the remote JMX node.

safeToReuse
final static SafeClone safeToReuse(Code)
These objects are safe to reuse in callByValue operations

Constructor Detail
InvokerInterceptor
public InvokerInterceptor()(Code)
Exposed for externalization.

Method Detail
createMarshalledValueForCallByValue
protected IMarshalledValue createMarshalledValueForCallByValue(Object value) throws IOException(Code)

getLocal
public static Invoker getLocal()(Code)
Get the local invoker reference, useful for optimization.

hasLocalTarget
public boolean hasLocalTarget(Invocation invocation)(Code)
Whether there is a local target
Parameters:
  invocation - true when in the registry

invoke
public Object invoke(Invocation invocation) throws Exception(Code)
The invocation on the delegate, calls the right invoker. Remote if we are remote, local if we are local.

invokeInvoker
protected Object invokeInvoker(Invocation invocation) throws Exception(Code)
Invoke using invoker
Parameters:
  invocation - the invocation the result
throws:
  Exception - for any error

invokeLocal
protected Object invokeLocal(Invocation invocation) throws Exception(Code)
Invoke using local invoker
Parameters:
  invocation - the invocation the result
throws:
  Exception - for any error

invokeLocalMarshalled
protected Object invokeLocalMarshalled(Invocation invocation) throws Exception(Code)
This method is for local calls when using pass-by-value

invokeMarshalled
protected Object invokeMarshalled(Invocation invocation) throws Exception(Code)
Invoke using local invoker and marshalled
Parameters:
  invocation - the invocation the result
throws:
  Exception - for any error

isClustered
public boolean isClustered(Invocation invocation)(Code)
Whether we are in a clustered environment
NOTE: This should be future compatible under any new design where a prior target chooser interceptor picks a non HA target than that code being inside a ha invoker.
Parameters:
  invocation - the invocation true when a clustered invoker

isLocal
public boolean isLocal()(Code)
Returns wether we are local to the originating container or not. true when we have the same GUID

isLocal
public boolean isLocal(Invocation invocation)(Code)
Whether the target is local
Parameters:
  invocation - the invocation true when the target is local

readExternal
public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException(Code)
Un-externalize this instance.
We check timestamps of the interfaces to see if the instance is in the original VM of creation

setLocal
public static void setLocal(Invoker invoker)(Code)
Set the local invoker reference, useful for optimization.

writeExternal
public void writeExternal(ObjectOutput out) throws IOException(Code)
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.
