Listening for subtable creation
package networktablesdesktopclient;
import edu.wpi.first.networktables.NetworkTable;
import edu.wpi.first.networktables.NetworkTableInstance;
public class SubTableListenerExample {
public static void main(String[] args) {
new SubTableListenerExample().run();
}
public void run() {
NetworkTableInstance inst = NetworkTableInstance.getDefault();
NetworkTable table = inst.getTable("datatable");
inst.startClientTeam(190);
table.addSubTableListener((parent, name, table) -> {
System.out.println("Parent: " + parent + " Name: " + name);
}, false);
try {
Thread.sleep(100000);
} catch (InterruptedException ex) {
System.out.println("Interrupted!");
}
}
}
In this example a listener is defined that listens for creation of subtables one level down from the listener. That is subtables with the key “/datatable/<any-table-name>”. This will fire the callback for each existing subtable, then continue to listen for new subtables created immediately below “datatable” in this case.
