ShapefileFeatureLocking

public ShapefileFeatureLocking(ShapefileDataStore shapefileDataStore,
                               Set hints,
                               SimpleFeatureType featureType)

Method Detail

getDataStore

public DataStore getDataStore()

Description copied from class: AbstractFeatureSource

Overrides to explicitly type narrow the return type to DataStore

Specified by:

getDataStore in interface FeatureSource<SimpleFeatureType,SimpleFeature>

Specified by:

getDataStore in class AbstractFeatureSource

Returns:

the data source providing this FeatureSource

addFeatureListener

public void addFeatureListener(FeatureListener listener)

Description copied from interface: FeatureSource

Registers a listening object that will be notified of changes to this FeatureSource.

Parameters:

listener - the new listener

removeFeatureListener

public void removeFeatureListener(FeatureListener listener)

Description copied from interface: FeatureSource

Removes an object from this FeatureSource's listeners.

Parameters:

listener - the listener to remove

getSchema

public SimpleFeatureType getSchema()

Description copied from interface: FeatureSource

Retrieves the schema (feature type) that will apply to features retrieved from this FeatureSource.

For a homogeneous data source such as a shapefile or a database table, this schema be that of all features. For a heterogeneous data source, e.g. a GML document, the schema returned is the lowest common denominator across all features.

Returns:

the schema that will apply to features retrieved from this FeatureSource

getBounds

public ReferencedEnvelope getBounds(Query query)
                             throws 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<SimpleFeatureType,SimpleFeature>

Overrides:

getBounds in class AbstractFeatureSource

Parameters:

query - Query we are requesting the bounds of

Returns:

null representing the lack of an optimization

Throws:

IOException - on any errors calculating the bounds

getInfo

public ResourceInfo getInfo()

Description copied from interface: FeatureSource

Returns information describing this FeatureSource which may include title, description and spatial parameters. Note that in the returned ResourceInfo object, the distinction between feature name and schema (feature type) name applies as discussed for FeatureSource.getName().

Specified by:

getInfo in interface FeatureSource<SimpleFeatureType,SimpleFeature>

Overrides:

getInfo in class AbstractFeatureSource
