read: function( encoded )
Deserialize an encoded polyline string and return a vector feature.
| encoded | {String} An encoded polyline string |
{OpenLayers.Feature.Vector} A vector feature with a linestring.
decode: function( encoded, dims, opt_factor )
Deserialize an encoded string and return an array of n-dimensional points.
| encoded | {String} An encoded string |
| dims | {int} The dimension of the points that are returned |
{Array(Array(int))} An array containing n-dimensional arrays of coordinates.
encode: function ( points, dims, opt_factor )
Serialize an array of n-dimensional points and return an encoded string
| points | {Array(Array(int))} An array containing n-dimensional arrays of coordinates |
| dims | {int} The dimension of the points that should be read |
{String} An encoded string
encodeDeltas: function( numbers, dimension, opt_factor )
