Class DynValuePOA

java.lang.Object
org.omg.PortableServer.Servant
org.omg.DynamicAny.DynValuePOA
All Implemented Interfaces:
InvokeHandler, DynAnyOperations, DynValueCommonOperations, DynValueOperations
Direct Known Subclasses:
DynValuePOATie

public abstract class DynValuePOA extends Servant implements DynValueOperations, InvokeHandler
DynValue objects support the manipulation of IDL non-boxed value types. The DynValue interface can represent both null and non-null value types. For a DynValue representing a non-null value type, the DynValue's components comprise the public and private members of the value type, including those inherited from concrete base value types, in the order of definition. A DynValue representing a null value type has no components and a current position of -1.

Warning: Indiscriminantly changing the contents of private value type members can cause the value type implementation to break by violating internal constraints. Access to private members is provided to support such activities as ORB bridging and debugging and should not be used to arbitrarily violate the encapsulation of the value type.

    • _invoke

      public OutputStream _invoke(String $method, InputStream in, ResponseHandler $rh)
      Description copied from interface: InvokeHandler
      Invoked by the ORB to dispatch a request to the servant. ORB passes the method name, an InputStream containing the marshalled arguments, and a ResponseHandler which the servant uses to construct a proper reply. Only CORBA SystemException may be thrown by this method. The method must return an OutputStream created by the ResponseHandler which contains the marshalled reply. A servant must not retain a reference to the ResponseHandler beyond the lifetime of a method invocation. Servant behaviour is defined as follows:

      1. Determine correct method, and unmarshal parameters from InputStream.

      2. Invoke method implementation.

      3. If no user exception, create a normal reply using ResponseHandler.

      4. If user exception occurred, create exception reply using ResponseHandler.

      5. Marshal reply into OutputStream returned by ResponseHandler.

      6. Return OutputStream to ORB.

      Specified by:
      _invoke in interface InvokeHandler
      Parameters:
      $method - The method name.
      in - The InputStream containing the marshalled arguments.
      $rh - The ResponseHandler which the servant uses to construct a proper reply
      Returns:
      The OutputStream created by the ResponseHandler which contains the marshalled reply
    • _all_interfaces

      public String[] _all_interfaces(POA poa, byte[] objectId)
      Description copied from class: Servant
      Used by the ORB to obtain complete type information from the servant.
      Specified by:
      _all_interfaces in class 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.
