     * } catch (GeometryOperationNotSupportedException gonse) {

     * }

     * 

     *  // Fill the operation context with required params

     * FromWKBGeometryOperationContext ctx = new FromWKBGeometryOperationContext();

     * 

     *  // Here is the main loop where you call the operation

     * for (int i=0; i<myGeometriesWKB.length; i++) {

     *    ctx.setData(myGeometriesWKB[i]);

     *    Object result = geomOp.invoke(null, ctx);

     * @return Geometry operation

     * @throws GeometryOperationNotSupportedException

     *             Returns this exception if there is not a registered operation

     *             with
