Java org.omg.PortableServer Class Servant（JDK8）

Constructor Detail

• Servant

  public Servant()

Method Detail

• _get_delegate

  public final Delegate _get_delegate()

  Gets the ORB vendor-specific implementation of PortableServer::Servant.

  Returns:

  _delegate the ORB vendor-specific implementation of PortableServer::Servant.

• _set_delegate

  public final void _set_delegate(Delegate delegate)

  Supports the Java ORB portability interfaces by providing a method for classes that support ORB portability through delegation to set their delegate.

  Parameters:

  delegate - ORB vendor-specific implementation of the PortableServer::Servant.

• _this_object

  public final Object _this_object()

  Allows the servant to obtain the object reference for the target CORBA object it is incarnating for that request.

  Returns:

  this_object Object reference associated with the request.

• _this_object

  public final Object _this_object(ORB orb)

  Allows the servant to obtain the object reference for the target CORBA Object it is incarnating for that request.

  Parameters:

  orb - ORB with which the servant is associated.

  Returns:

  _this_object reference associated with the request.

• _orb

  public final ORB _orb()

  Returns the instance of the ORB currently associated with the Servant (convenience method).

  Returns:

  orb the instance of the ORB currently associated with the Servant.

• _poa

  public final POA _poa()

  Allows easy execution of common methods, equivalent to PortableServer::Current:get_POA.

  Returns:

  poa POA associated with the servant.

• _object_id

  public final byte[] _object_id()

  Allows easy execution of common methods, equivalent to calling PortableServer::Current::get_object_id.

  Returns:

  object_id the Object ID associated with this servant.

• _default_POA

  public POA _default_POA()

  Returns the root POA from the ORB instance associated with the servant. Subclasses may override this method to return a different POA.

  Returns:

  default_POA the POA associated with the Servant.

• _is_a

  public boolean _is_a(String repository_id)

  Checks to see if the specified repository_id is present on the list returned by _all_interfaces() or is the repository_id for the generic CORBA Object.

  Parameters:

  repository_id - the repository_id to be checked in the repository list or against the id of generic CORBA objects.

  Returns:

  is_a boolean indicating whether the specified repository_id is in the repository list or is same as a generic CORBA object.

• _non_existent

  public boolean _non_existent()

  Checks for the existence of an Object. The Servant provides a default implementation of _non_existent() that can be overridden by derived servants.

  Returns:

  non_existent true if that object does not exist, false otherwise.

• _get_interface_def

  public Object _get_interface_def()

  Returns an InterfaceDef object as a CORBA::Object that defines the runtime type of the CORBA::Object implemented by the Servant. The invoker of _get_interface_def must narrow the result to an InterfaceDef in order to use it.

  This default implementation of _get_interface_def() can be overridden by derived servants if the default behavior is not adequate. As defined in the CORBA 2.3.1 specification, section 11.3.1, the default behavior of _get_interface_def() is to use the most derived interface of a static servant or the most derived interface retrieved from a dynamic servant to obtain the InterfaceDef. This behavior must be supported by the Delegate that implements the Servant.

  Returns:

  get_interface_def an InterfaceDef object as a CORBA::Object that defines the runtime type of the CORBA::Object implemented by the Servant.

• _all_interfaces

  public abstract String[] _all_interfaces(POA poa,
                                           byte[] objectId)

  Used by the ORB to obtain complete type information from the servant.

  Parameters:

  poa - POA with which the servant is associated.

  objectId - is the id corresponding to the object associated with this servant.

  Returns:

  list of type information for the object.
