- All Implemented Interfaces:
- java.lang.Runnable
- public class DataStack
- extends ThreadSupport
The DataStack class accelerates communication between client and
Tunnel server. It packages several consiquen client's request in one package.
The package then is delivered to Tunnel server. Tunnel server unpack the request
and perform them in original sequence.
Results from performed sequence are also packaged and returned to client.
Not all remote calls may be used for such agregated calls. The Tunneling is aware
about calls that it may package. These calls are such as calls that return void or
remote object stubs or references.
There is one instance of DataStack for each Server URL.
