All Implemented Interfaces:

public class POAImpl
extends ObjectAdapterBase
implements POA

POAImpl is the implementation of the Portable Object Adapter. It contains an implementation of the POA interfaces specified in COBRA 2.3.1 chapter 11 (formal/99-10-07). This implementation is moving to comply with CORBA 3.0 due to the many clarifications that have been made to the POA semantics since CORBA 2.3.1. Specific comments have been added where 3.0 applies, but note that we do not have the new 3.0 APIs yet.

public int getManagerId()

Description copied from interface: ObjectAdapter

Return the ID of the AdapterManager for this object adapter.

Specified by:

getManagerId in interface ObjectAdapter

Specified by:

getManagerId in class ObjectAdapterBase

getState

public short getState()

Description copied from interface: ObjectAdapter

Return the current state of this object adapter (see org.omg.PortableInterceptors for states.

Specified by:

getState in interface ObjectAdapter

Specified by:

getState in class ObjectAdapterBase

getInterfaces

public String[] getInterfaces(Object servant,
                     byte[] objectId)

Description copied from interface: ObjectAdapter

Return the most derived interface for the given servant and objectId.

Specified by:

getInterfaces in interface ObjectAdapter

Specified by:

getInterfaces in class ObjectAdapterBase

getObjectCopierFactory

protected ObjectCopierFactory getObjectCopierFactory()

Specified by:

getObjectCopierFactory in class ObjectAdapterBase

enter

public void enter()
           throws OADestroyed

Description copied from interface: ObjectAdapter

enter must be called before each request is invoked on a servant.

Specified by:

enter in interface ObjectAdapter

Specified by:

enter in class ObjectAdapterBase

Throws:

OADestroyed - is thrown when an OA has been destroyed, which requires a retry in the case where an AdapterActivator is present.

exit

public void exit()

Description copied from interface: ObjectAdapter

exit must be called after each request has been completed. If enter is called, there must always be a corresponding exit.

Specified by:

exit in interface ObjectAdapter

Specified by:

exit in class ObjectAdapterBase

getInvocationServant

public void getInvocationServant(OAInvocationInfo info)

Description copied from interface: ObjectAdapter

Get the servant for the request given by the parameters. info must contain a valid objectId in this call. The servant is set in the InvocationInfo argument that is passed into this call.

Specified by:

getInvocationServant in interface ObjectAdapter

Specified by:

getInvocationServant in class ObjectAdapterBase

Parameters:

info - is the InvocationInfo object for the object reference

getLocalServant

public Object getLocalServant(byte[] objectId)

Description copied from interface: ObjectAdapter

Get the servant corresponding to the given objectId, if this is supported. This method is only used for models where the servant is an ObjectImpl, which allows the servant to be used directly as the stub. This allows an object reference to be replaced by its servant when it is unmarshalled locally. Such objects are not ORB mediated.

Specified by:

getLocalServant in interface ObjectAdapter

Specified by:

getLocalServant in class ObjectAdapterBase

returnServant

public void returnServant()

Called from the subcontract to let this POA cleanup after an invocation. Note: If getServant was called, then returnServant MUST be called, even in the case of exceptions. This may be called multiple times for a single request.

Specified by:

returnServant in interface ObjectAdapter

Specified by:

returnServant in class ObjectAdapterBase
