public abstract class AbstractDataStore

extends java.lang.Object

implements DataStore, Handler

the class implements the methods of the DataStore interface thats implementation is common to all data stores and some additional methods that will be used if the data store is controlled using observer/event handling mechanism.

Constructor Summary

protected

AbstractDataStore(java.net.URL datastoreConfigSource) Creates a new AbstractDataStore object.

Method Summary

protected void	fireResponse(OGCWebServiceEvent event) notifies the registered WFSResponseListener that the peromance of request has been finished and submits the result.
DatastoreConfiguration	getConfiguration() returns the configuration of the datastore
DBConnectionPool	getConnectionPool()
void	handleRequest(OGCWebServiceEvent event) implements the handleRequest(..)
void	handleResponse(OGCWebServiceEvent event) handles the response of an OGC web service
boolean	isInterested(OGCWebServiceEvent event) returns true if the handler is interested in a event
boolean	isKnownFeatureType(java.lang.String featureType) returns true if the submitted feature type is known by the data store
void	registerFeatureType(java.lang.String featureType) registers a feature type to the data store.
void	registerHandler(Handler handler) registers a Handler so this Handler is able to act as a proxy to the registered handler
void	removeFeatureType(java.lang.String featureType) the inverse operation to registerFeatureType
void	removeHandler(Handler handler)

AbstractDataStore

protected AbstractDataStore(java.net.URL datastoreConfigSource)
                     throws DataStoreException

Creates a new AbstractDataStore object.

Parameters:

datastoreConfigSource -

Throws:

DataStoreException

Method Detail

getConfiguration

public DatastoreConfiguration getConfiguration()

returns the configuration of the datastore

getConnectionPool

public DBConnectionPool getConnectionPool()

Returns:

registerFeatureType

public void registerFeatureType(java.lang.String featureType)

registers a feature type to the data store.

Specified by:

registerFeatureType in interface DataStore

removeFeatureType

public void removeFeatureType(java.lang.String featureType)

the inverse operation to registerFeatureType

Specified by:

removeFeatureType in interface DataStore

See Also:

registerFeatureType(String)

isKnownFeatureType

public boolean isKnownFeatureType(java.lang.String featureType)

returns true if the submitted feature type is known by the data store

Specified by:

isKnownFeatureType in interface DataStore

isInterested

public boolean isInterested(OGCWebServiceEvent event)

returns true if the handler is interested in a event

Specified by:

isInterested in interface Handler

registerHandler

public void registerHandler(Handler handler)
