isGenerateIds

protected boolean isGenerateIds()

Description copied from class: AbstractFeatureFactory

Determines if the service automatically generates unique IDs for all queryable features. Note that if this operation returns true, the id expression is not evaluated.

Specified by:

isGenerateIds in class AbstractFeatureFactory<PostgisFeature,SimpleFeatureServiceSqlStatement>

Returns:

true if the service generates id}

createFeatures

public List<PostgisFeature> createFeatures(SimpleFeatureServiceSqlStatement sqlStatement,
                                           BoundingBox boundingBox,
                                           SwingWorker workerThread)
                                    throws FeatureFactory.TooManyFeaturesException,
                                           Exception

Description copied from interface: FeatureFactory

Returns instances of features FT that match the optional query and that fall into the optional BoundingBox.
Applies layerProperties (if set) on all Features (if the type of the feature implements the interface InheritsLayerProperties). The SwingWorker instance can be used to set the progress of the operation and to check the worker thread was canceled. The state of the features list after a the operation was canceled is undefined.

Parameters:

sqlStatement - optional query of type QT to select the features to be returned

boundingBox - optional BoundingBox to restrict the features to be returned

workerThread - an optional worker thread that is observed

Returns:

a list of matching features of type FT

Throws:

FeatureFactory.TooManyFeaturesException - if the maximum number of features is reached during processing

Exception - if something went wrong during parsing

createAttributes

public Vector createAttributes(SwingWorker workerThread)
                        throws FeatureFactory.TooManyFeaturesException,
                               Exception

Description copied from interface: FeatureFactory

Method that does not create FeatureServiceAttributes. In general, FeatureServiceAttributes need only to be created when the layer is initialized.

Parameters:

workerThread - DOCUMENT ME!

Returns:

a list of FeatureServiceAttributes.

Throws:

FeatureFactory.TooManyFeaturesException - if the maximum number of features is reached during processing

UnsupportedOperationException - if the factory does not support the creation attributes

Exception - if something went wrong during parsing

cleanup

protected void cleanup(Statement statement)

DOCUMENT ME!

Parameters:

statement - DOCUMENT ME!

clone

Description copied from interface: FeatureFactory

DOCUMENT ME!

Specified by:

clone in interface FeatureFactory<PostgisFeature,SimpleFeatureServiceSqlStatement>

Specified by:

clone in class AbstractFeatureFactory<PostgisFeature,SimpleFeatureServiceSqlStatement>

Returns:

Parameters:

query - DOCUMENT ME!

bb - DOCUMENT ME!

Returns:

Description copied from interface: FeatureFactory

Returns instances of features FT that match the optional query and that fall into the optional BoundingBox.
Applies layerProperties (if set) on all Features (if the type of the feature implements the interface InheritsLayerProperties).
