Method Detail

getDataStore

public DataStore getDataStore()

Description copied from interface: FeatureSource

Access to the DataStore implementing this FeatureStore.

You may use this to access such as namespace provided by DataStore.

Returns:

DataStore implementing this FeatureStore

See Also:

FeatureSource.getDataStore()

addFeatureListener

public void addFeatureListener(FeatureListener listener)

Description copied from interface: FeatureSource

Adds a listener to the list that's notified each time a change to the FeatureStore occurs.

Parameters:

listener - FeatureListener

See Also:

FeatureSource.addFeatureListener(org.geotools.data.FeatureListener)

removeFeatureListener

public void removeFeatureListener(FeatureListener listener)

Description copied from interface: FeatureSource

Removes a listener from the list that's notified each time a change to the FeatureStore occurs.

Parameters:

listener - FeatureListener

See Also:

FeatureSource.removeFeatureListener(org.geotools.data.FeatureListener)

getSchema

public FeatureType getSchema()

Description copied from interface: FeatureSource

Retrieves the featureType that features extracted from this datasource will be created with.

The schema returned is the LCD supported by all available Features. In the common case of shapfiles and database table this schema will match that of every feature available. In the degenerate GML case this will simply reflect the gml:AbstractFeatureType.

Returns:

the schema of features created by this datasource.

See Also:

FeatureSource.getSchema()

getBounds

public com.vividsolutions.jts.geom.Envelope getBounds()
                                               throws java.io.IOException

Description copied from class: AbstractFeatureSource

Retrieve Bounds of all Features.

Currently returns null, consider getFeatures().getBounds() instead.

Subclasses may override this method to perform the appropriate optimization for this result.

Specified by:

getBounds in interface FeatureSource

Overrides:

getBounds in class AbstractFeatureSource

Returns:

null representing the lack of an optimization

Throws:

java.io.IOException - DOCUMENT ME!

See Also:

FeatureSource.getBounds()

getBounds

public com.vividsolutions.jts.geom.Envelope getBounds(Query query)
                                               throws java.io.IOException

Description copied from class: AbstractFeatureSource

Retrieve Bounds of Query results.

Currently returns null, consider getFeatures( query ).getBounds() instead.

Subclasses may override this method to perform the appropriate optimization for this result.

Specified by:

getBounds in interface FeatureSource

Overrides:

getBounds in class AbstractFeatureSource

Parameters:

query - Query we are requesting the bounds of

Returns:

null representing the lack of an optimization

Throws:

java.io.IOException - DOCUMENT ME!

See Also:

FeatureSource.getBounds(org.geotools.data.Query)

getFeatures

public FeatureCollection getFeatures()

Description copied from class: AbstractFeatureSource

Retrieve all Features.

Specified by:

getFeatures in interface FeatureSource

Overrides:

getFeatures in class AbstractFeatureSource

Returns:

FeatureResults of all Features in FeatureSource

See Also:

FeatureSource.getFeatures()

getFeatures

public FeatureCollection getFeatures(Filter filter)

Description copied from class: AbstractFeatureSource

Retrieve all Feature matching the Filter.

Specified by:

getFeatures in interface FeatureSource

Overrides:

getFeatures in class AbstractFeatureSource

Parameters:

filter - Indicates features to retrieve

Returns:

FeatureResults indicating features matching filter

See Also:

FeatureSource.getFeatures(org.geotools.filter.Filter)

getFeatures

public FeatureCollection getFeatures(Query query)

Description copied from class: AbstractFeatureSource

Provides an interface to for the Resutls of a Query.

Various queries can be made against the results, the most basic being to retrieve Features.

Specified by:

getFeatures in interface FeatureSource

Overrides:

getFeatures in class AbstractFeatureSource

Parameters:

query -

Returns:

See Also:

FeatureSource.getFeatures(org.geotools.data.Query)

getTransaction

public Transaction getTransaction()

Description copied from class: AbstractFeatureSource

Retrieve the Transaction this FeatureSource is opperating against.

For a plain FeatureSource that cannot modify this will always be Transaction.AUTO_COMMIT.

Overrides:

getTransaction in class AbstractFeatureSource

Returns:

Transacstion FeatureSource is opperating against
