org.geotools.data.store .ContentFeatureSource

All known Subclasses:   org.geotools.data.jdbc .JDBCFeatureSource,  org.geotools.data.store .ContentFeatureStore,
ContentFeatureSource
abstract public class ContentFeatureSource implements FeatureSource(Code)
Abstract implementation of FeatureSource.
Implementations are based around feature collections. Subclasses must implement the following methods to provide feature collection based data access:

ContentFeatureSource.all(ContentState) : Access to entire dataset
ContentFeatureSource.filtered(ContentState,Filter) : Access to filtered dataset
In addition, subclasses must implement ContentFeatureSource.buildFeatureType(SimpleTypeFactory) in which constructs the feature type for the feature.

Field Summary
protected ContentEntry entry
     The entry for the feautre source.
protected Transaction transaction


Constructor Summary
public ContentFeatureSource(ContentEntry entry)


Method Summary
final public void addFeatureListener(FeatureListener listener)

abstract protected FeatureCollection all(ContentState state)
     FeatureCollection representing the entire contents.
abstract protected FeatureType buildFeatureType()
     Creates a feature type for the entry.
An implementation of this method should create a new instance of SimpleTypeBuilder , injecting it with the factory provided by the datastore via.
abstract protected FeatureCollection filtered(ContentState state, Filter filter)
     FeatureCollection representing a subset of available content.

final public int getCount(Query query)

final public DataStore getDataStore()

public ContentEntry getEntry()

final public FeatureCollection getFeatures()

final public FeatureCollection getFeatures(Query query)

final public FeatureCollection getFeatures(Filter filter)

public Logger getLogger()
     Returns the data store logger.
