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.

Specified by:

createFeatures in interface FeatureFactory<DefaultFeatureServiceFeature,String>

Parameters:

query - 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

offset - the start index

limit - a limit

orderBy - the attributes, the features should be ordered by

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

getEnvelope

public com.vividsolutions.jts.geom.Geometry getEnvelope()

DOCUMENT ME!

Returns:

the envelope

setEnvelope

public void setEnvelope(com.vividsolutions.jts.geom.Geometry envelope)

DOCUMENT ME!

Parameters:

envelope - the envelope to set
