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

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

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

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.

getCount

public int getCount(Query query)

Description copied from interface: FeatureSource

Gets the number of the features that would be returned by this query.

If getBounds(Query) returns -1 due to expense consider using getFeatures(Query).getCount() as a an alternative.

Specified by:

getCount in interface FeatureSource

Overrides:

getCount in class AbstractFeatureSource

Parameters:

query - Query we are requesting the count of

Returns:

-1 representing the lack of an optimization

getBounds

public com.vividsolutions.jts.geom.Envelope getBounds()

Description copied from interface: FeatureSource

Gets the bounding box of this datasource.

With getBounds(Query) this becomes a convenience method for getBounds(Query.ALL), that is the bounds for all features contained here.

If getBounds() returns null due to expense consider using getFeatures().getBounds() as a an alternative.

Specified by:

getBounds in interface FeatureSource

Overrides:

getBounds in class AbstractFeatureSource

Returns:

null representing the lack of an optimization
