Class EventThemeTransform

java.lang.Object
  org.gvsig.fmap.dal.feature.AbstractFeatureStoreTransform
      org.gvsig.app.eventtheme.dal.feature.EventThemeTransform

All Implemented Interfaces:

java.lang.Cloneable, org.gvsig.fmap.dal.feature.FeatureStoreTransform, 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.

                throws org.gvsig.fmap.dal.exception.DataException

This method initializes the transformation, sets the name of the parameters and sets the value of the FeatureType returned by the transformation.

Parameters:

store - The original store.

geometryFieldName - The field that contains the geometric attribute.

xFieldName - The field that contains the X coordinate.

yFieldName - The field that contains the Y coordinate.
