                                       Class expectedType)

Description copied from interface: LocalClientRequestDispatcher

Returns a Java reference to the servant which should be used for this request. servant_preinvoke() is invoked by a local stub. If a ServantObject object is returned, then 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.

Specified by:

servant_preinvoke in interface LocalClientRequestDispatcher

Parameters:

self - The object reference which delegated to this delegate.

operation - a string containing the operation name. The operation name corresponds to the operation name as it would be encoded in a GIOP request.

expectedType - a Class object representing the expected type of the servant. The expected type is the Class object associated with the operations class of the stub's interface (e.g. A stub for an interface Foo, would pass the Class object for the FooOperations interface).

Returns:

a ServantObject object. The method may return a null value if it does not wish to support this optimization (e.g. due to security, transactions, etc). The method must return null if the servant is not of the expected type.
