A LinearRing is a closed, one-dimensional feature. A LinearRing that crosses itself or touches itself at a single point is invalid and operations on it may fail. Parameters ---------- coordinates : sequence A sequence of (x, y [,z]) numeric coordinate pairs or triples, or an array-like with shape (N, 2) or (N, 3). Also can be a sequence of Point objects. Notes ----- Rings are automatically closed. There is no need to specify a final coordinate pair identical to the first. Examples -------- Construct a square ring. >>> from shapely import LinearRing >>> ring = LinearRing( ((0, 0), (0, 1), (1 ,1 ), (1 , 0)) ) >>> ring.is_closed True >>> list(ring.coords) [(0.0, 0.0), (0.0, 1.0), (1.0, 1.0), (1.0, 0.0), (0.0, 0.0)] >>> ring.length 4.0 Nc|tjdSt|tr7t |t ur|S|j s td|j}nt|drtj|}t|tjr/tj|jtjrned}tj |Dcgc] }|| c}}tj|jtjs t#dt%|dk(rtjdStj&|}t|t s t#d|Scc}w)z!Create a new LinearRing geometry.zLINEARRING EMPTYz"An input LineString must be valid. __array__c|t|tr|jdS|Dcgc] }t|c}Scc}wNr) isinstancercoordsfloat)ocs r_coordsz#LinearRing.__new__.._coordsWs2!!U+ xx{*234Qa444s9z&Inconsistent coordinate dimensionalityrz/Invalid values passed to LinearRing constructor)rfrom_wktrrtyper is_validrr hasattrnpasarrayndarray issubdtypedtypenumberarray ValueErrorlen linearrings)self coordinatesr$r"geoms r__new__zLinearRing.__new__=s>  ##$67 7  Z 0K J."" ))&'KLL*00 {K0 jj5 +rzz2r}}!!29985 !hhK'Hq 'HI }}[%6%6 B%%MNN { q ##$67 7"";/$ +NO O (IsFc2dt|jdS)z9Return a GeoJSON-like mapping of the LinearRing geometry.r r&r4)tupler r3s r__geo_interface__zLinearRing.__geo_interface__ms%U4;;5GHHrc>ttj|dffS)zPickle support.
