Class EventThemeTransform

java.lang.Object
org.gvsig.fmap.dal.feature.AbstractFeatureStoreTransform
org.gvsig.app.eventtheme.dal.feature.EventThemeTransform
All Implemented Interfaces:
Cloneable, org.gvsig.fmap.dal.feature.FeatureStoreTransform, org.gvsig.tools.lang.Cloneable, org.gvsig.tools.persistence.Persistent
public class EventThemeTransform extends org.gvsig.fmap.dal.feature.AbstractFeatureStoreTransform
This class implements a transformation for a events theme. The original DataStore have to have a couple of attributes, one with the X coordinate and the second one with the Y coordinate. The result of the transformation is a DataStore that has a new geometric attribute and its value is a point with the coordinates specified in the original DataStore.
