InstanceResolver
abstract public class InstanceResolver (Code)
Determines the instance that serves the given request packet.

The JAX-WS spec always use a singleton instance to serve all the requests, but this hook provides a convenient way to route messages to a proper receiver.

Externally, an instance of InstanceResolver is associated with WSEndpoint .

Possible Uses

One can use WS-Addressing message properties to decide which instance to deliver a message. This would be an important building block for a stateful web services.

One can associate an instance of a service with a specific WS-RM session.

Method Summary
public static  InstanceResolver<T>createDefault(Class<T> clazz, boolean bool)
    
public static  InstanceResolver<T>createDefault(Class<T> clazz)
     Creates a default InstanceResolver that serves the given class.
public  InvokercreateInvoker()
     Wraps this InstanceResolver into an Invoker .
protected static  TcreateNewInstance(Class<T> cl)
    
public static  InstanceResolver<T>createSingleton(T singleton)
     Creates a InstanceResolver implementation that always returns the specified singleton instance.
public  voiddispose()
     Called by WSEndpoint when WSEndpoint.dispose is called.
public  voidpostInvoke(Packet request, T servant)
     Called by the default Invoker after the method call is done.
abstract public  Tresolve(Packet request)
     Decides which instance of 'T' serves the given request message.

This method is called concurrently by multiple threads. It is also on a criticail path that affects the performance. A good implementation should try to avoid any synchronization, and should minimize the amount of work as much as possible.
Parameters:
  request - Always non-null.

public  voidstart(WSWebServiceContext wsc, WSEndpoint endpoint)
     Called by WSEndpoint when it's set up.
public  voidstart(WebServiceContext wsc)
    



Method Detail
createDefault
public static InstanceResolver<T> createDefault(Class<T> clazz, boolean bool)(Code)



createDefault
public static InstanceResolver<T> createDefault(Class<T> clazz)(Code)
Creates a default InstanceResolver that serves the given class.



createInvoker
public Invoker createInvoker()(Code)
Wraps this InstanceResolver into an Invoker .



createNewInstance
protected static T createNewInstance(Class<T> cl)(Code)



createSingleton
public static InstanceResolver<T> createSingleton(T singleton)(Code)
Creates a InstanceResolver implementation that always returns the specified singleton instance.



dispose
public void dispose()(Code)
Called by WSEndpoint when WSEndpoint.dispose is called. This allows InstanceResolver to do final clean up.

This method is guaranteed to be only called once by WSEndpoint .




postInvoke
public void postInvoke(Packet request, T servant)(Code)
Called by the default Invoker after the method call is done. This gives InstanceResolver a chance to do clean up.

Alternatively, one could override InstanceResolver.createInvoker() to create a custom invoker to do this in more flexible way.

The default implementation is a no-op.
Parameters:
  request - The same request packet given to InstanceResolver.resolve(Packet) method.
Parameters:
  servant - The object returned from the InstanceResolver.resolve(Packet) method.
since:
   2.1.2




resolve
abstract public T resolve(Packet request)(Code)
Decides which instance of 'T' serves the given request message.

This method is called concurrently by multiple threads. It is also on a criticail path that affects the performance. A good implementation should try to avoid any synchronization, and should minimize the amount of work as much as possible.
Parameters:
  request - Always non-null. Represents the request message to be served.The caller may not consume the Message.




start
public void start(WSWebServiceContext wsc, WSEndpoint endpoint)(Code)
Called by WSEndpoint when it's set up.

This is an opportunity for InstanceResolver to do a endpoint-specific initialization process.
Parameters:
  wsc - The WebServiceContext instance to be injectedto the user instances (assuming InstanceResolver




start
public void start(WebServiceContext wsc)(Code)
InstanceResolver.start(WSWebServiceContext,WSEndpoint)
