      Throws:
      IllegalArgumentException - if either no or more than one Geom type was found in the given struct

      public static Struct.StructMember findRequiredGeometryMember(Struct struct)

      Convenience version of findGeometryMember where required flag is set to true

    • hasGeometryMember

      public static boolean hasGeometryMember(Struct struct)

      Convenience version to check if the struct has a geometry member

    • getContentSummary

      public static String getContentSummary(Tuple tuple)
      Returns:
      a concise summary of the tuple's content. Values may be shortened, or in the case of geometries will be excluded completely.
