Class SDEDataStore

java.lang.Object
  org.deegree_impl.services.wfs.AbstractDataStore
      org.deegree_impl.services.wfs.sde.SDEDataStore

All Implemented Interfaces:

DataStore, java.util.EventListener, Handler

public class SDEDataStore

extends AbstractDataStore

The class provides reading and writing access to ESRI shape- 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 features once read from a shape-file in memory to provide a mauch fast access to them. The cache can be configured throw the configuration XML-document that also contains the names and locations of the shapes handled by an instance of the SDEDataStore.
