Syntax

   @JSONGeometry( <command>, <json flavor>, <attrName> [, PREFER_ERROR_OVER_REJECTION] )

Arguments

   <command>

      To specify whether to import or export the geometry of a feature from/to
      an attribute.

      Range: TO_ATTRIBUTE | FROM_ATTRIBUTE

   <json flavor>

      The name of the JSON flavor in which the geometry will be read/written.
      Currently only GeoJSON and EsriJSON are supported.

      Range: GEOJSON | ESRIJSON

   <attrName>

      The name of the attribute to have the geometry saved to or retrieved from
      the feature.

      Range: String

    PREFER_ERROR_OVER_REJECTION

      When specified, this factory will error on sick features instead of rejecting them.

Description

      Note: For a method of storing and retrieving geometry in an attribute
      where the geometry is fully preserved (including measures and complex
      chains involving arcs), see @Geometry.

   This command is used to set or get the feature geometry. The <json flavor>
   string indicates the type of JSON object to read or write. Depending on the
   <command> string, the attribute given will be the source or destination for
   the geometry of the feature.

      Note: In TO_ATTRIBUTE mode, if the feature has no geometry, then the
      resulting attribute will have a blank value, because the GeoJSON
      specifications provide no way to represent a "null" geometry. Conversely,
      however, in FROM_ATTRIBUTE mode, if the specified attribute has a blank
      value, then the feature's geometry will be left untouched and a warning
      output.
