6.2 Receiving a File
A file can be retrieved from one of the datalogger file systems using the
GetFileTran class. This class starts a file receive transaction with the
datalogger and delivers fragments of the file to the application as they are
received using
GetFileClient.on_fragment(com.campbellsci.pakbus.GetFileTran, byte[]).
The following example demonstrates this process:
import com.campbellsci.pakbus.*;
import java.net.*;
import java.io.*;
class Example6_2 implements GetFileClient
{
private Network network;
private Socket socket;
private boolean complete;
private Datalogger my_cr1000;
private OutputStream output;
