public function simplify(graphics:Array, responder:IResponder = null):AsyncToken
Alters the given geometries to make their definitions topologically legal with respect to their geometry type.
On completion, the simplifyComplete event is fired and the optional callback function is invoked.
Both the callback and event handlers receive an array of Graphic that contains the simplified geometries.
Note: The XY tolerance property of the geometry's associated spatial reference is used during the simplify operation for polylines and polygons,
which might slightly change exact locations.
Parameters
| graphics:Array — Array of graphics.

| |
| responder:IResponder (default = null) |

public static const SPATIAL_REL_COINCIDENCE:String = "esriGeometryRelationLineCoincidence"
The boundaries of the geometries must share an intersection, but the relationship between the interiors of the shapes is not considered (they could overlap, one could be contained in the other, or their interiors could be disjoint).
This relation applies to polylines and polygons.
public static const SPATIAL_REL_CROSS:String = "esriGeometryRelationCross"
Two polylines cross if they share only points in common, at least one of which is not an endpoint.
A polyline and a polygon cross if they share a polyline in common on the interior of the polygon which is not equivalent to the entire polyline.
Cross is a Clementini operator.
If either one of the geometries is empty, the geometries do not cross.
public static const SPATIAL_REL_DISJOINT:String = "esriGeometryRelationDisjoint"
Two geometries are disjoint if their intersection is empty.
Two geometries intersect if disjoint is "false".
Disjoint is a Clementini operator.
public static const SPATIAL_REL_IN:String = "esriGeometryRelationIn"
The base geometry is within the comparison geometry if the base geometry is the intersection of the geometries and the intersection of their interiors is not empty.
Within is a Clementini operator.
Within is the opposite operator of contains.
An empty geometry is within another geometry, unless the other geometry is empty.
public static const SPATIAL_REL_INTERIORINTERSECTION:String = "esriGeometryRelationInteriorIntersection"
Geometries intersect excluding boundary touch.
public static const SPATIAL_REL_INTERSECTION:String = "esriGeometryRelationIntersection"
Geometry interiors intersect or boundaries touch, same as 'not disjoint'.
public static const SPATIAL_REL_LINETOUCH:String = "esriGeometryRelationLineTouch"
Two geometries are said to touch when the intersection of the geometries is non-empty, but the intersection of their interiors is empty.
This evaluates if the touch occurs along a boundary (not a point).
Valid for polygons.
public static const SPATIAL_REL_OVERLAP:String = "esriGeometryRelationOverlap"
Two polylines share a common sub-line, or two polygons share a common sub-area.
Overlaps is a Clementini operator.
Two geometries do not overlap if either one is empty.
public static const SPATIAL_REL_POINTTOUCH:String = "esriGeometryRelationPointTouch"
Two geometries are said to touch when the intersection of the geometries is non-empty, but the intersection of their interiors is empty.
This evaluates if the touch occurs at a point (not a boundary).
public static const SPATIAL_REL_RELATION:String = "esriGeometryRelationRelation"
Allows specification of any relationship defined using the Shape Comparison Language.
public static const SPATIAL_REL_TOUCH:String = "esriGeometryRelationTouch"
The union of esriGeometryRelationPointTouch and esriGeometryRelationLineTouch.
Two geometries are said to touch when the intersection of the geometries is non-empty, but the intersection of their interiors is empty.
Touches is a Clementini operator.
For example, a point touches a polyline only if the point is coincident with one of the polyline end points.
If either one of the two geometries is empty, the geometries are not touched.
public static const SPATIAL_REL_WITHIN:String = "esriGeometryRelationWithin"
Same as esriGeometryRelationIn but also allows polylines that are strictly on the boundaries of polygons to be considered 'in' the polygon.
