PolygonExtracter

public PolygonExtracter(java.util.List comps)

Constructs a PolygonExtracterFilter with a list in which to store Polygons found.

Method Detail

getPolygons

public static java.util.List getPolygons(Geometry geom)

Returns the Polygon components from a single geometry. If more than one geometry is to be processed, it is more efficient to create a single PolygonExtracterFilter instance and pass it to multiple geometries.

filter

public void filter(Geometry geom)

Description copied from interface: GeometryFilter

Performs an operation with or on geom.

Specified by:

filter in interface GeometryFilter

Parameters:

geom - a Geometry to which the filter is applied.
