Class DefaultDBGateway

java.lang.Object
  gov.usda.gdpc.AbstractDBGateway
      gov.usda.gdpc.DefaultDBGateway

All Implemented Interfaces:

DBGateway

public final class DefaultDBGateway

extends AbstractDBGateway

This is the default implementation of the database gateway. Most of the function comes from the abstract class that is extends, but it does provide the getInstance() method which returns the singleton instance of this class. In most cases, this gateway should be used. Only if you need more specialized function would you need to extend the abstract class and create a gateway of your own.
