| ObjectImpl | | abstract public class ObjectImpl implements org.omg.CORBA.Object(Code) | | The common base class for all stub classes; provides default implementations
of the org.omg.CORBA.Object methods. All method implementations are
forwarded to a Delegate object stored in the ObjectImpl
instance. ObjectImpl allows for portable stubs because the
Delegate can be implemented by a different vendor-specific ORB.

| _servant_postinvoke | | public void _servant_postinvoke(ServantObject servant)(Code) | | Is called by the local stub after it has invoked an operation
on the local servant that was previously retrieved from a
call to the method _servant_preinvoke.
The _servant_postinvoke method must be called
if the _servant_preinvoke
method returned a non-null value, even if an exception was thrown
by the method invoked by the servant. For this reason, the call
to the method _servant_postinvoke should be placed
in a Java finally clause.
Parameters:
servant - the instance of the ServantObjectreturned by the _servant_preinvoke method |
| _servant_preinvoke | | public ServantObject _servant_preinvoke(String operation, Class expectedType)(Code) | | Returns a Java reference to the local servant that should be used for sending
a request for the method specified. If this ObjectImpl
object is a local stub, it will invoke the _servant_preinvoke
method before sending a request in order to obtain the
ServantObject instance to use.
If a ServantObject object is returned, its servant
field has been set to an object of the expected type (Note: the object may
or may not be the actual servant instance). The local stub may cast
the servant field to the expected type, and then invoke the operation
directly. The ServantRequest object is valid for only one
invocation and cannot be used for more than one invocation.
Parameters:
operation - a String containing the name of the methodto be invoked. This name should correspond to the method name asit would be encoded in a GIOP request.
Parameters:
expectedType - a Class object representing theexpected type of the servant that is returned. This expected type is the Class object associated with theoperations class for the stub's interface. For example, a stub for an interface Foo would pass the Class object for the FooOperationsinterface. (1) a ServantObject object, which may or maynot be the actual servant instance, or (2) null if(a) the servant is not local or (b) the servant has ceased tobe local due to a ForwardRequest from a POA ServantManager
throws:
org.omg.CORBA.BAD_PARAM - if the servant is not the expected type |
| _set_delegate | | public void _set_delegate(Delegate delegate)(Code) | | Sets the Delegate for this ObjectImpl instance to the given
