Class DBControl

java.lang.Object
PamController.PamControlledUnit
generalDatabase.DBControl
All Implemented Interfaces:
PamSettings, PamSettingsSource, SettingsNameProvider
Direct Known Subclasses:
DBControlSettings, DBControlUnit
public abstract class DBControl extends PamControlledUnit implements PamSettings, PamSettingsSource
Database system for accessing data in just about any type of odbc database.

This gets used in two slightly different ways in Pamguard. The first is the obvious reading and writing of data to a variety of tables. The second is the loading of settings from the PAmguard_settings and the PamguardModules tables tables in which all program settings were serialised and stored as 6 bit ascii strings each time PAMGUARD started collecting data.

So that an instance of DBControl can be made that doesn't load settings, two sub classes have been made: DBContorlUnit for normal use and DBControlSettings for reading in settings information.
