5.5 Get Values: An Alternative to Data Collection
If the application needs only to read values from a single field in the datalogger
table, it can do so using the GetValuesTran class. This collection method
differs from data collection in that the client specifies the data type in which it
wants to receive values, only one field can be polled (if that field is an array,
multiple values from that field can be returned), time stamp and record number
information are not returned by the datalogger, and table definitions are not
required.
The following example illustrates the use of the get values transaction:
import java.net.*;
import java.io.*;
import com.campbellsci.pakbus.*;
public class Example5_5 implements GetValuesClient
{
public Example5_5()
{ }
public void on_complete(
GetValuesTran transaction,
int outcome,
Record values) throws Exception
