The Editor component provides out-of-the-box editing capabilities using an editable layer in a FeatureService.The Legend component displays labels and symbols for some or all of the layers in the map.The default navigation component of the map.The Scale Bar component for the Map.The minimum and maximum x- and y-coordinates of a bounding box.Base class for geometry objects.A location defined by an x- and y-coordinate (in map units).An array of MapPoints.An array of rings where each ring is an array of MapPoints.An array of paths where each path is an array of MapPoints.An extent defined using latitude and longitude, but stored internally in web mercator units.A location defined using latitude and longitude but stored in web mercator units.Allows you to work with a dynamic map service resource exposed by the ArcGIS Server REST API (available inArcGIS Server 9.3 and above).Allows you to work with an Image Service resource exposed by the ArcGIS Server REST API (available inArcGIS Server 9.3 and above).Allows you to work with a cached map service resource exposed by the ArcGIS Server REST API (available inArcGIS Server 9.3 and above).Base class for all dynamic layers that can be added to a map.The feature layer can be used to display features from one single layer of either a Feature Service or aMap Service.Allows you to view a geoprocessing task result.A layer that contains one or more Graphic features.Base class for all layers that can be added to a map.The MapImageLayer class is used to add georeferenced images to the map.Base class for all tiled layers that can be added to a map.A class break renderer symbolizes each graphic based on the value of some numeric attribute.Base class for all renderers - use SimpleRenderer, ClassBreaksRenderer or UniqueValueRenderer with aGraphicsLayer.A renderer that uses one symbol only.Temporal renderer which uses the time field of a FeatureLayer.A unique value renderer symbolizes groups of graphics that have matching attributes.Used to draw linear features on the graphics layer.Used to draw multiple symbols on a single graphic.Base class for polygon symbols.Used to display info markers (or bubble markers), containing your own content, at points (MapPoint) on thegraphics layer.Base class for line symbols.Base class for marker symbols.Used to draw polygon features on the graphics layer using an image that gets repeated over and over.Used to draw points and multipoints on the graphics layer using an image.Used to draw polygon features on the graphics layer using simple patterns.Used to draw linear features on the graphics layer using simple line patterns.Used to draw points and multipoints (or nodes of polylines and polygons) on the graphics layer usingsimple markers.Base class for all symbols.Used to display text at points on the graphics layer.Tool that supports functionality to create new geometries by drawing them: points (MAPPOINT orMULTIPOINT), lines (LINE, POLYLINE, or FREEHAND_POLYLINE), polygons (FREEHAND_POLYGON or POLYGON), rectangles (EXTENT) and circles (CIRCLE).Functionality to move graphics or modify individual vertices, i.e., edit the geometry of existinggraphics.Tool that supports basic navigation, such as pan and zoom.。
