gnu.CORBA.Poa

Class AOM

public class AOM
extends Object
Implements the conception of the Active Object Map. If the POA supports the RETAIN policy, it maintains an Active Object Map, that associates Object Ids with active servants. Each association constitutes an active object. We use a single map for all POAs on the given orb.

Nested Class Summary

class
AOM.Obj
The reference data about the object, placed on the AOM.

Method Details

add

public AOM.Obj add(byte[] key,
                   gnuServantObject object,
                   Servant servant,
                   gnuPOA poa)
Add the new object to the repository.
Parameters:
key - the object key.
object - the object to add.
servant - a servant, serving the given object.
poa - the POA, where the object is connected.

add

public AOM.Obj add(ServantDelegateImpl delegate)
Add the new object to the repository.
Parameters:
delegate - the delegate, providing data about the servant, key, POA and object.

add

public AOM.Obj add(gnuServantObject object,
                   Servant servant,
                   gnuPOA poa)
Add the new object to the repository. The object key is generated automatically.
Parameters:
object - the object to add.
servant - a servant, serving the given object.
poa - the poa, where the object is connected.
Returns:
the newly created object record.

findObject

public AOM.Obj findObject(Object stored_object)
Get the record of the stored object. If the object is mapped several times under the different keys, one of the mappings is used.
Parameters:
stored_object - the stored object
Returns:
the record about the stored object, null if this object is not stored here.

findServant

public AOM.Obj findServant(Servant servant)
Find the reference info for the given servant. If the servant is mapped to several objects, this returns the first found occurence.
Parameters:
servant - a servant to find.
Returns:
the servant/object/POA binding or null if no such found.

findServant

public AOM.Obj findServant(Servant servant,
                           boolean inactive)
Find the reference info for the given servant. If the servant is mapped to several objects, this returns the first found occurence.
Parameters:
servant - a servant to find.
Returns:
the servant/object/POA binding or null if no such found.

generateObjectKey

protected byte[] generateObjectKey(Object object)
Generate the object key, unique in the currently running java virtual machine. The passed object parameter is currently not in use.
Returns:
the generated key.

get

public AOM.Obj get(byte[] key)
Get the stored object.
Parameters:
key - the key (in the byte array form).
Returns:
the matching object, null if none is matching.

getFreeId

public static byte[] getFreeId()
Get the next free 8 byte id, surely unique between calls of this method for the currently running virtual machine.

keySet

public Set<E> keySet()
Get the map key set.

put

public void put(AOM.Obj obj)
Put back the definition structure that has probably been removed earlier.

remove

public void remove(byte[] key)
Remove the given object, indiciating it by the key.
