Method Detail

initialize

public MyTransform initialize(FeatureStore store,
                     java.lang.String geomName,
                     java.lang.String xname,
                     java.lang.String yname)
                       throws DataException

Initializes the transform by assigning the source store and the names of the necessary attributes.

Parameters:

store - source store.

geomName - name of the geometry attribute in the default feature type from the source store.

xname - name of the attribute containing the X coordinates

yname - name of the attribute containing the Y coordinates

Throws:

DataException

applyTransform

public void applyTransform(Feature source,
                  EditableFeature target)
                    throws DataException

Applies this transform to a target editable feature, using data from the source feature.

Parameters:

source - feature whose data will be used as source

target - feature in which the source data will be copied

Throws:

DataException
