Class DBFeatureKeyIntFactory

java.lang.Object
  edu.indiana.iucbrf.feature.FeatureKeyFactory
      edu.indiana.iucbrf.feature.FeatureKeyIntFactory
          edu.indiana.iucbrf.feature.DBFeatureKeyIntFactory

All Implemented Interfaces:

java.io.Serializable

public class DBFeatureKeyIntFactory
extends FeatureKeyIntFactory

In contrast to FeatureKeyIntFactory, DBFeatureKeyIntFactory does not store the next key in memory. Rather, it reads from the database each time a new key is needed, and writes to the database each time the next available key is incremented.
