Example 1 with CompositeCurve

use of org.opengis.geometry.complex.CompositeCurve in project geotoolkit by Geomatys.

the class GeometryUtils method getLineCharSequences.

 * Recursively populates the specified List with LineCharSequences corresponding
 * to the primitive elements of the specified CompositeCurve.
 * Returns null if any element of the CompositeCurve cannot be converted
 * to a LineString.
 * @param cc The CompositeCurve of interest
 * @param lsList The ArrayList to be populated
 * @return The populated List, or null if not valid
