nl_tokens: * @method union ( <range > ) @returns DateRange @short Returns a new DateRange with the earliest starting point as its start and the latest ending point as its end . If the two ranges do not intersect this will effectively remove the gap between them . @example
pl_tokens: function ( range ) { return <mask> DateRange ( this . start < range . start ? this . start : range . start , this . end > range . end ? this . end : range . end ) ; }
