public class RemoteFlatFieldImpl
extends RemoteFieldImpl
implements RemoteFlatField

RemoteFlatFieldImpl is the VisAD remote adapter for FlatField.

Another way to approach the problem of moving data to a remote machine would be to have a remote class which serializes a sample and copies it over to the remote machine where it is cached for fast access. This would be a much better approach if the application does a lot of computations on a set of static samples.
