module RGeo
module Feature
# == SFS 1.1 Description
#
# A LinearRing is a LineString that is both closed and simple.
#
# == Notes
#
# LinearRing is defined as a module and is provided primarily
# for the sake of documentation. Implementations need not necessarily
# include this module itself. Therefore, you should not depend on the
# kind_of? method to check type. Instead, use the provided check_type
# class method (or === operator) defined in the Type module.
module LinearRing
include LineString
extend Type
# Returns +true+ if the ring is oriented in a counter clockwise direction
# otherwise returns +false+.
#
# == Notes
#
# Not a standard SFS method for linear rings, but added for convenience.
