All Implemented Interfaces:

PIHandler, Closeable, AutoCloseable

public class PINoOpHandlerImpl
extends Object
implements PIHandler

This is No-Op implementation of PIHandler. It is used in ORBConfigurator to initialize a piHandler before the Persistent Server Activation. This PIHandler implementation will be replaced by the real PIHandler in ORB.postInit( ) call.

Method Detail

close

public void close()

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

initialize

public void initialize()

Description copied from interface: PIHandler

Complete the initialization of the PIHandler. This will execute the methods on the ORBInitializers, if any are defined. This must be done here so that the ORB can obtain the PIHandler BEFORE the ORBInitializers run, since they will need access to the PIHandler through the ORB.

Specified by:

initialize in interface PIHandler

destroyInterceptors

public void destroyInterceptors()

Specified by:

destroyInterceptors in interface PIHandler

objectAdapterCreated

public void objectAdapterCreated(ObjectAdapter oa)

Description copied from interface: PIHandler

Called when a new object adapter is created.

Specified by:

objectAdapterCreated in interface PIHandler

Parameters:

oa - The adapter associated with the interceptors to be invoked.

adapterManagerStateChanged

public void adapterManagerStateChanged(int managerId,
                                       short newState)

Description copied from interface: PIHandler

Called whenever a state change occurs in an adapter manager.

Specified by:

adapterManagerStateChanged in interface PIHandler

Parameters:

managerId - managerId The adapter manager id

newState - newState The new state of the adapter manager, and by implication of all object adapters managed by this manager.

adapterStateChanged

public void adapterStateChanged(ObjectReferenceTemplate[] templates,
                                short newState)

Description copied from interface: PIHandler

Called whenever a state change occurs in an object adapter that was not caused by an adapter manager state change.

Specified by:

adapterStateChanged in interface PIHandler

Parameters:

templates - The templates that are changing state.

newState - The new state of the adapters identified by the templates.

disableInterceptorsThisThread

public void disableInterceptorsThisThread()

Description copied from interface: PIHandler

Called for pseudo-ops to temporarily disable portable interceptor hooks for calls on this thread. Keeps track of the number of times this is called and increments the disabledCount.

Specified by:

disableInterceptorsThisThread in interface PIHandler

enableInterceptorsThisThread

public void enableInterceptorsThisThread()

Description copied from interface: PIHandler

Called for pseudo-ops to re-enable portable interceptor hooks for calls on this thread. Decrements the disabledCount. If disabledCount is 0, interceptors are re-enabled.

Specified by:

enableInterceptorsThisThread in interface PIHandler

invokeClientPIStartingPoint

public void invokeClientPIStartingPoint()
                                 throws RemarshalException

Description copied from interface: PIHandler

Called when the send_request or send_poll portable interception point is to be invoked for all appropriate client-side request interceptors.

Specified by:

invokeClientPIStartingPoint in interface PIHandler

Throws:

RemarshalException

invokeClientPIEndingPoint

public Exception invokeClientPIEndingPoint(int replyStatus,
                                           Exception exception)

Description copied from interface: PIHandler

Called when the appropriate client ending interception point is to be invoked for all apporpriate client-side request interceptors.

Specified by:

invokeClientPIEndingPoint in interface PIHandler

Parameters:

replyStatus - One of the constants in iiop.messages.ReplyMessage indicating which reply status to set.

exception - The exception before ending interception points have been invoked, or null if no exception at the moment.

Returns:

The exception to be thrown, after having gone through all ending points, or null if there is no exception to be thrown. Note that this exception can be either the same or different from the exception set using setClientPIException. There are four possible return types: null (no exception), SystemException, UserException, or RemarshalException.

makeCompletedClientRequest

public Exception makeCompletedClientRequest(int replyStatus,
                                            Exception exception)

Description copied from interface: PIHandler

Called when a retry is needed after initiateClientPIRequest but before invokeClientPIRequest. In this case, we need to properly balance initiateClientPIRequest/cleanupClientPIRequest calls, but WITHOUT extraneous calls to invokeClientPIEndingPoint (see bug 6763340).

Specified by:

makeCompletedClientRequest in interface PIHandler

Parameters:

replyStatus - One of the constants in iiop.messages.ReplyMessage indicating which reply status to set.

exception - The exception before ending interception points have been invoked, or null if no exception at the moment.

Returns:

The exception to be thrown, after having gone through all ending points, or null if there is no exception to be thrown. Note that this exception can be either the same or different from the exception set using setClientPIException. There are four possible return types: null (no exception), SystemException, UserException, or RemarshalException.

Specified by:

initiateClientPIRequest in interface PIHandler

Parameters:

diiRequest - True if this is to be a DII request, or false if it is a "normal" request. In the DII case, initiateClientPIRequest is called twice and we need to ignore the second one.

cleanupClientPIRequest
