Hi,
Needed some inputs on the following topics within
AltRMI :-
<1 topic="Method Invocation" >
We have method signature(string) being passed from
the client to the server for
carrying out the invocation of a specific method on
the server.
How about replacing it with a int value ,which is
nothing but a index to a method array maintained
on the server for that specific remote object & thus
in the process removing the string comparisons
involved ?
Comments ??

<2 topic="Pass-by-Reference & Pass-by-value decision "
>
Right now CallbackEnabled client stream treats ALL of
its arguments , which are interfaces ,
as pass-by-reference entities and transports its stub
instead of passing it by value(serializing) to the
server.
We might need to employ some means to indicate an
argument as either Pass-By-Reference or POV
entity in the arguments.
We can do something like:
callBackTestListenerImpl = new
CallBackTestListenerImpl(2);
//pass-by-value ..serialized across..this is the
default
addCallBackListener(callBackTestListenerImpl);
//pass-by-reference .callbacks can be made on this
reference by the server
addCallBackListener(new
PassReference(callBackTestListenerImpl));
===or===
We can use something like RMI's exportObject(..)
Therefore:
CallBackTestListenerImpl callBackTestListenerImpl_1
= new CallBackTestListenerImpl(2);
CallBackTestListenerImpl callBackTestListenerImpl_2
= new CallBackTestListenerImpl(2);
//This specific reference will be passed by value
when its passed on to the server as an argument
AltrmiHost.exposeObject(callBackTestListenerImpl_2);
addCallBackListener(callBackTestListenerImpl_1);//pass-by-value
.serialized across
addCallBackListener(callBackTestListenerImpl_2);//pass-by-reference
..
Comments?
