a-synchone construction of an object

[Anthony]

Hi,
Can anyone help me out here,

I'm looking for a design (pattern?) for a-synchronic construction of a
class.
I need this design in a framework which will run in a multithreaded system.
I want a class (client) in threadA to a-synchronously construct a class
(server) in threadB.
Both threads will probably need a kind of construction manager object.
For passing the request I will probably need to use a parameterised class.
The client class running in threadA sends a request, and the construction
manager running in threadB, will handle the request.

Does this problem sounds familiar to anyone? Is there a standard solution to
this problem?

Thanks in advance,
Anthony Lansbergen

Look at "factory method".

Doesn't sound right. You want the threadB to construct an object to
be used in the threadA, upon a request from threadA. Nothing asynch
in that, AFAICS.

Both threads will probably need a kind of construction manager object.

More like a request manager.

For passing the request I will probably need to use a parameterised class.

You just need a custom request.

The client class running in threadA sends a request, and the construction
manager running in threadB, will handle the request.
Yep.

this problem?

No. There are no threads in the standard. But you're on the right
track. ThreadA sends a request, threadB handles it. Once the object
has been created, threadB notifies threadA about the location of it.
After than threadA can use the object.

Not a C++ language problem, by the way.
