Syntax

   @Close([FORCE_CLOSE_Z])
   @Close([HANDLE_ARCS])
 
Arguments

   FORCE_CLOSE_Z

      Forces the z-value to be compared, in addition to the default comparison
      of the x/y values, when comparing equality between the start and end 
      point. If this is set to Yes, then the z-value will be checked to 
      determine if the input needs closing, otherwise, only the x/y values
      will be checked.
   
      Range: Yes | No

   HANDLE_ARCS

      Deprecated, but must be kept for legacy purposes.

      Range: N/A

Description

   This function takes a feature with linear geometry and closes it by 
   connecting the first point with the last point. It is used to artificially 
   close polygons with an edge missing. For example, some data sets do not 
   include the map neat line, so any areas abutting the map edge are not closed. 
   @Close is useful in these situations.
    
   Warning! Use this function with caution - in most situations, simply 
   connecting the first point with the last point will not produce a valid 
   polygon.

   If @Close is invoked on a feature that is already a polygon, it will do 
   nothing. If the feature was tagged as being a line and its first and last 
   points are the same, then this function will simply adjust the feature's 
   fme_geometry to be fme_polygon and no change is made to the geometry.
