gnu.CORBA.Poa

Class LocalDelegate

Implemented Interfaces:
IorProvider
public class LocalDelegate
extends Delegate
implements IorProvider
A local delegate, transferring all object requests to the locally available servant. This class is involved in handling the method invocations on the local object, obtained by POA.create_reference_with_id.

Field Summary

gnuPOA
poa

Constructor Summary

LocalDelegate(gnuServantObject an_object, gnuPOA a_poa, byte[] an_id)
Create a local delegate, forwarding requests to the servant that must also be an invocation handler.

Method Summary

Request
create_request(Object target, Context context, String method, NVList parameters, NamedValue returns)
Create request for using with DII.
Request
create_request(Object target, Context context, String method, NVList parameters, NamedValue returns, ExceptionList exceptions, ContextList ctx_list)
Create request for using with DII.
Object
duplicate(Object target)
Return this.
InvokeHandler
getHandler(String method, CookieHolder cookie)
Return the associated invocation handler.
IOR
getIor()
Get the IOR of the connected object.
Object
get_interface_def(Object target)
Not in use.
int
hash(Object target, int maximum)
Get hash code.
InputStream
invoke(Object target, OutputStream output)
Make an invocation.
boolean
is_a(Object a_servant, String idl_id)
Check if this object could be named by the given repository id.
boolean
is_equivalent(Object target, Object other)
boolean
non_existent(Object target)
Always return false.
ORB
orb(Object target)
Return the ORB of the associated POA.
void
release(Object target)
void
releaseReply(Object target, InputStream input)
Request
request(Object target, String method)
OutputStream
request(Object target, String method, boolean response_expected)
