Methods Summary
public byte[]	activate_object(org.omg.PortableServer.Servant p_servant) This operation generates an Object Id and enters the Object Id and the specified servant in the Active Object Map. param p_servant servant to be associated with an object to be activated. return POA generated object id. exception ServantAlreadyActive is raised if the POA has UNIQUE_ID policy and servant is is already in the Active Object Map. exception WrongPolicy raised if the SYSTEM_ID and RETAIN policies are not specified.
public void	activate_object_with_id(byte[] id, org.omg.PortableServer.Servant p_servant) This operation enters an association between the specified Object Id and the specified servant in the Active Object Map. param id object id for the object to be activated. param p_servant servant to be associated with the object. exception ServantAlreadyActive raised if the POA has the UNIQUE_ID policy and the servant is already in the Active Object Map. exception ObjectAlreadyActive raised if the object is already active in the POA. exception WrongPolicy raised if the RETAIN policy is is not specified.
public org.omg.PortableServer.POA	create_POA(java.lang.String adapter_name, org.omg.PortableServer.POAManager a_POAManager, org.omg.CORBA.Policy[] policies) This operation creates a new POA as a child of the target POA. param adapter_name identifies the new POA with respect to other POAs with the same parent POA. param a_POAManager specifies the POA Manager to be associated with the new POA. param policies specifies policy objects to be associated with the POA to control its behavior. exception AdapterAlreadyExists specifies that the target POA already has a child POA with the specified name. exception InvalidPolicy is raised if any of the policy objects are not valid for the ORB, or are in conflict, or require an administrative action that has not been performed.
public org.omg.PortableServer.IdAssignmentPolicy	create_id_assignment_policy(org.omg.PortableServer.IdAssignmentPolicyValue value) These operations each return a reference to a policy object with the specified value. param value policy type return IdAssignmentPolicy Object.
public org.omg.PortableServer.IdUniquenessPolicy	create_id_uniqueness_policy(org.omg.PortableServer.IdUniquenessPolicyValue value) These operations each return a reference to a policy object with the specified value. param value policy type return IdUniquenessPolicy Object.
public org.omg.PortableServer.ImplicitActivationPolicy	create_implicit_activation_policy(org.omg.PortableServer.ImplicitActivationPolicyValue value) These operations each return a reference to a policy object with the specified value. param value policy type return ImplicitActivationPolicy Object.
public org.omg.PortableServer.LifespanPolicy	create_lifespan_policy(org.omg.PortableServer.LifespanPolicyValue value) These operations each return a reference to a policy object with the specified value. param value policy type return LifespanPolicy Object.
public org.omg.CORBA.Object	create_reference(java.lang.String intf) This operation creates an object reference that encapsulates a POA-generated Object Id value and the specified interface repository id. param intf rep id for creating an object reference. return object reference created using intf. exception WrongPolicy if SYSTEM_ID policy is not specified.
public org.omg.CORBA.Object	create_reference_with_id(byte[] oid, java.lang.String intf) This operation creates an object reference that encapsulates the specified Object Id and interface repository Id values. It does not cause an activation to take place. The resulting reference may be passed to clients, so that subsequent requests on those references will cause the object to be activated if necessary, or the default servant used, depending on the applicable policies. param oid object id for creating an objref param intf rep id for creating an objref return object reference created using oid and intf exception BAD_PARAM is raised if the POA has the SYSTEM_ID policy and it detects that the Object Id value was not generated by the system or for this POA.
public org.omg.PortableServer.RequestProcessingPolicy	create_request_processing_policy(org.omg.PortableServer.RequestProcessingPolicyValue value) These operations each return a reference to a policy object with the specified value. param value policy type return RequestProcessingPolicy Object.
public org.omg.PortableServer.ServantRetentionPolicy	create_servant_retention_policy(org.omg.PortableServer.ServantRetentionPolicyValue value) These operations each return a reference to a policy object with the specified value. param value policy type return ServantRetentionPolicy Object.
public org.omg.PortableServer.ThreadPolicy	create_thread_policy(org.omg.PortableServer.ThreadPolicyValue value) These operations each return a reference to a policy object with the specified value. param value policy type return ThreadPolcy Object
public void	deactivate_object(byte[] oid) This operation causes the ObjectId specified in the oid parameter to be deactivated. An ObjectId which has been deactivated continues to process requests until there are no active requests for that ObjectId. A deactivated ObjectId is removed from the Active Object Map when all requests executing for that ObjectId have completed. param oid Object Id for the object to be deactivated. exception ObjectNotActive if the object with the specified oid is not in the Active Object Map. exception WrongPolicy raised if the RETAIN policy is is not specified.
public void	destroy(boolean etherealize_objects, boolean wait_for_completion) This operation destroys the POA and all descendant POAs. All descendant POAs are destroyed (recursively) before the destruction of the containing POA. The POA so destroyed (that is, the POA with its name) may be re-created later in the same process. param etherealize_objects flag to indicate whether etherealize operation on servant manager needs to be called. param wait_for_completion flag to indicate whether POA and its children need to wait for active requests and the etherealization to complete.
public org.omg.PortableServer.POA	find_POA(java.lang.String adapter_name, boolean activate_it) If the target POA is the parent of a child POA with the specified name (relative to the target POA), that child POA is returned. param adapter_name POA name to be found. param activate_it if a POA with the specified name does not exist and the value of the activate_it parameter is TRUE, the target POA's AdapterActivator, if one exists, is invoked. return POA if one exists or is activated by the AdapterActivator. return AdapterNonExistent is raised if POA with a specified name cannot be found or activated using AdapaterActivator.
public org.omg.PortableServer.Servant	get_servant() This operation returns the default servant associated with the POA. return p_servant default servant associated with a POA. exception NoServant raised if no default servant is associated with the POA. exception WrongPolicy raised if the USE_DEFAULT_SERVANT policy is not specified.
public org.omg.PortableServer.ServantManager	get_servant_manager() If the ServantRetentionPolicy of the POA is RETAIN, then the ServantManager argument (imgr) shall support the ServantActivator interface. For a NON_RETAIN policy, the ServantManager shall support the ServantLocator interface. If the argument is nil, or does not support the required interface, then the OBJ_ADAPTER exception is raised. return ServantManager associated with a POA or null if none exists. exception WrongPolicy raised if the USE_SERVANT_MANAGER policy is not specified.
public byte[]	id() This returns the unique id of the POA in the process in which it is created. It is for use by portable interceptors. This id is guaranteed unique for the life span of the POA in the process. For persistent POAs, this means that if a POA is created in the same path with the same name as another POA, these POAs are identical and, therefore, have the same id. For transient POAs, each POA is unique.
public org.omg.CORBA.Object	id_to_reference(byte[] oid) If an object with the specified Object Id value is currently active, a reference encapsulating the information used to activate the object is returned. param oid id of the object for which the reference is returned. return the object reference exception ObjectNotActive if the Object Id value is not active in the POA. exception WrongPolicy if the RETAIN policy is not present.
public org.omg.PortableServer.Servant	id_to_servant(byte[] oid) If the POA has the RETAIN policy and the specified ObjectId is in the Active Object Map, this operation returns the servant associated with that object in the Active Object Map. Otherwise, if the POA has the USE_DEFAULT_SERVANT policy and a default servant has been registered with the POA, this operation returns the default servant. param oid object id for the which the servant is returned. return servant associated with oid. exception ObjectNotActive is raised if ObjectId is is not in the Active Object Map (for RETAIN policy), or no default servant is registered (for USE_DEFAULT_SERVANT policy). exception WrongPolicy is raised if the RETAIN policy or the USE_DEFAULT_SERVANT policy is not present.
public byte[]	reference_to_id(org.omg.CORBA.Object reference) This operation returns the Object Id value encapsulated by the specified reference. This operation is valid only if the reference was created by the POA on which the operation is being performed. The object denoted by the reference does not have to be active for this operation to succeed. param reference the object reference from which the object id needs to be returned. return object id encapsulated in the reference. exception WrongAdapter if the reference was not created by the POA specified in the reference. exception WrongPolicy declared to allow future extensions.
public org.omg.PortableServer.Servant	reference_to_servant(org.omg.CORBA.Object reference) If the POA has the RETAIN policy and the specified object is present in the Active Object Map, this operation returns the servant associated with that object in the Active Object Map. Otherwise, if the POA has the USE_DEFAULT_SERVANT policy and a default servant has been registered with the POA, this operation returns the default servant. If the object reference was not created by this POA, the WrongAdapter exception is raised. (OMG Issue on inconsistency with the POA.IDL. param reference object reference for which the servant is returned. return servant associated with the reference. exception WrongPolicy if neither the RETAIN policy or the USE_DEFAULT_SERVANT policy is present. exception ObjectNotActive if the servant is not present in the Active Object Map (for RETAIN) or no default servant is registered (for USE_DEFAULT_POLICY). exception WrongAdapter if reference was not created by this POA instance.
public byte[]	servant_to_id(org.omg.PortableServer.Servant p_servant) This operation has four possible behaviors. 1. If the POA has the UNIQUE_ID policy and the specified servant is active, the Object Id associated with that servant is returned. 2. If the POA has the IMPLICIT_ACTIVATION policy and either the POA has the MULTIPLE_ID policy or the specified servant is not active, the servant is activated using a POA-generated Object Id and the Interface Id associated with the servant, and that Object Id is returned. 3. If the POA has the USE_DEFAULT_SERVANT policy, the servant specified is the default servant, and the operation is being invoked in the context of executing a request on the default servant, then the ObjectId associated with the current invocation is returned. 4. Otherwise, the ServantNotActive exception is raised. param p_servant servant for which the object disi returned. return object id associated with the servant. exception ServantNotActive if the above rules and policy combination is not met. exception WrongPolicy if the USE_DEFAULT_SERVANT policy or a combination of the RETAIN policy and either the UNIQUE_ID or IMPLICIT_ACTIVATION policies are not present.
public org.omg.CORBA.Object	servant_to_reference(org.omg.PortableServer.Servant p_servant) This operation requires the RETAIN policy and either the UNIQUE_ID or IMPLICIT_ACTIVATION policies if invoked outside the context of an operation dispatched by this POA. It has four possible behaviors. 1. If the POA has both the RETAIN and the UNIQUE_ID policy and the specified servant is active, an object reference encapsulating the information used to activate the servant is returned. 2. If the POA has both the RETAIN and the IMPLICIT_ACTIVATION policy and either the POA has the MULTIPLE_ID policy or the specified servant is not active, the servant is activated using a POA-generated Object Id and the Interface Id associated with the servant, and a corresponding object reference is returned. 3. If the operation was invoked in the context of executing a request on the specified servant, the reference associated with the current invocation is returned. 4. Otherwise, the ServantNotActive exception is raised. param p_servant servant for which the object reference needs to be obtained. return object reference associated with the servant. exception WrongPolicy if the operation is not invoked in the context of executing a request on the specified servant and the required policies are not present. exception ServantNotActive if the above specified policies and rules are not met.
public void	set_servant(org.omg.PortableServer.Servant p_servant) This operation registers the specified servant with the POA as the default servant. This servant will be used for all requests for which no servant is found in the Active Object Map. param p_servant servant to be used as a default. exception WrongPolicy raised if the USE_DEFAULT_SERVANT policy is not specified.
public void	set_servant_manager(org.omg.PortableServer.ServantManager imgr) This operation sets the default servant manager associated with the POA. This operation may only be invoked once after a POA has been created. Attempting to set the servant manager after one has already been set will result in the BAD_INV_ORDER exception being raised. param imgr servant manager to be used as a default. exception WrongPolicy raised if the USE_SERVANT_MANAGER policy is not specified.
public org.omg.PortableServer.POAManager	the_POAManager() This attribute identifies the POA manager associated with the POA.
public org.omg.PortableServer.AdapterActivator	the_activator() This attribute identifies the adapter activator associated with the POA.
public void	the_activator(org.omg.PortableServer.AdapterActivator newThe_activator) This attribute identifies the adapter activator associated with the POA.
public org.omg.PortableServer.POA[]	the_children() This attribute identifies the current set of all child POAs of the POA. The set of child POAs includes only the POA's immediate children, and not their descendants.
public java.lang.String	the_name() This attribute identifies the POA relative to its parent. This name is assigned when the POA is created.
public org.omg.PortableServer.POA	the_parent() This attribute identifies the parent of the POA. The parent of the root POA is null.
