Class BNADataStore

java.lang.Object
  org.deegree_impl.services.wfs.AbstractDataStore
      org.deegree_impl.services.wfs.bna.BNADataStore

All Implemented Interfaces:

DataStore, java.util.EventListener, Handler

public class BNADataStore

extends AbstractDataStore

The class provides reading access to BNA files. The access is capsulated withing the query and transaction mechanism described at the OGC WFS specifications.

The data store uses a cache for keeping the entire featureset once read from a BNA file in memory to provide a much fast access to them.
