Field Details

Id

public final byte[] Id
The Id of this object.

manager

public final POAManager manager
The POA manager, used to control the work of this object.

The orb.

poa

public final gnuPOA poa
The poa that takes care about this object.

repository_ids

public final String[] repository_ids

Constructor Details

gnuServantObject

public gnuServantObject(String[] a_repository_ids,
                        byte[] an_id,
                        gnuPOA a_poa,
                        ORB_1_4 an_orb)
Create an object with no connected servant. The servant must be set later.
Parameters:
a_repository_ids - an array of repository ids, can be null (then ids will be requested from the servant).
an_id - the object id.
a_poa - the POA.

gnuServantObject

public gnuServantObject(Servant a_servant,
                        byte[] an_id,
                        ORB_1_4 an_orb,
                        gnuPOA a_poa)
Create a servant object, associated with the passed servant.
Parameters:
a_servant - a servant, serving this object.
an_id - an Object Id for this object.
Throws:
BAD_PARAM - if the passed servant is not an InvokeHandler.

gnuServantObject

public gnuServantObject(Servant a_servant,
                        gnuPOA a_poa)
Create a servant object, associated with the passed servant. Requests the object id from the servant. Depending on the policies of the servants POA, the calls are eithe not synchronized or synchronized on POA or ORB.
Parameters:
