Interface FileTransferMessageFactory

All Known Implementing Classes:

DFSMessageFactory, TestFactory

public interface FileTransferMessageFactory

This interface describes the methods that must be implemented by a file transfer message factory.

The message factory is required in order to instantiate messages that will be correctly routed on reception. Indeed, there are 2 types of routing implemented by Communicator and DistributedAgent (see Communicator's message handling method). In the case where routing is delegated to DistributedAgent, the type (i.e. the class) of a message is used to route it to the good agent. The message factory is therefore used by file transfer components in order to instantiate messages with the right type in order to be routed correctly.
