Creates a new OverlayEngine.

Method Detail

overlay

public FeatureCollection overlay(FeatureCollection a,
                        FeatureCollection b,
                        TaskMonitor monitor)

Creates the overlay of the two datasets. The attributes from both datasets will be transferred to the overlay.

Parameters:

a - the first dataset involved in the overlay

b - the second dataset involved in the overlay

Returns:

intersections of all pairs of input features

overlay

public FeatureCollection overlay(FeatureCollection a,
                        FeatureCollection b,
                        AttributeMapping mapping,
                        TaskMonitor monitor)

Creates the overlay of the two datasets. The attributes from the datasets will be transferred as specified by the AttributeMapping.

Parameters:

a - the first dataset involved in the overlay

b - the second dataset involved in the overlay

mapping - specifies which attributes are transferred

Returns:

intersections of all pairs of input features

addFeature

protected void addFeature(com.vividsolutions.jts.geom.Geometry intersection,
              FeatureCollection overlay,
              AttributeMapping mapping,
              Feature a,
              Feature b)

setSplittingGeometryCollections
