Generates dynamic rendering options (see esri.ags.layers.supportClasses.LayerDrawingOptions class)
for Reviewer workspace results.
This class automatically generates symbols and colors based on the contents of your
Reviewer workspace. Unique values in a DashboardResult are used to build UniqueValueRenderers.
These renderers are applied through LayerDrawingOptions to the REVTABLEPOINT, REVTABLELINE,
and REVTABLEPOLY layers in the ArcGIS Data Reviewer for Server Map Server.
Instances of this
class keep a cache of the symbols and colors used to render the map so that if the extent
of the features being drawn changes, the colors are kept consistent.
The colors are selected based on a predefined color palette that helps make each unique value
distinguishable from each other. However, using more than 20 unique values is not recommended
because the resulting rendered map will not be helpful for analysis. Colors are not randomly
selected for Severity and LifecycleStatus fields. Instead, a predefined color scale is
applied.
If you use a custom color map, the auto generated or predefined palettes are not used. The following
rules apply if the color map doesn't contain enough values to represent all unique values in
the DashboardResult:
- If useDefaultColorForMissingValues is set to false (default), colors for any values missing from the colorMap are generated from the color palette.
- If useDefaultColorForMissingValues is set to true, the current defaultColor is assigned to all values missing from the colorMap.
defaultColor:uint [write-only]
Sets the default color. Used when the system cannot determine
a color to apply to a symbol.
Implementation public function set defaultColor(value:uint):voidgetLayerDrawingOptionsLastResult:Object
Object returned from the last call to the getLayerDrawingOptions function.
The object holds two properties:
- layerDrawingOptionsArray - an array of LayerDrawingOptions, for point, line and polygon layers.
- colorMap - a collection of keys (unique field values) and color values
This property can be used as the source for data binding.

Example
// Event result object example:
{
"layerDrawingOptionsArray": [pointLayerDrawingOptions, lineLayerDrawingOptions, polygonLayerDrawingOptions],
"colorMap":{'roads':0xFFFFFF, 'trees':0x00FF00, ...}
}
lineSymbol:SimpleLineSymbol [write-only]
Sets the symbol used to render the reviewer map server's REVTABLELINE layer.
You can define the alpha, style and width properties. Color is determined by the
DashboardResult and ColorMap parameters passed to the getLayerDrawingOptions function.
Implementation public function set lineSymbol(value:SimpleLineSymbol):voidSee also
pointSymbol:SimpleMarkerSymbol [write-only]
Sets the symbol used to render the reviewer map server's REVTABLEPOINT layer. You can define the alpha, angle, outline, size,
style, xoffset, and yoffset properties. Color is determined by the DashboardResult and ColorMap
parameters passed to the getLayerDrawingOptions function.
Implementation public function set pointSymbol(value:SimpleMarkerSymbol):voidSee also
polySymbol:SimpleFillSymbol [write-only]
Sets the symbol used to render the reviewer map server's REVTABLEPOLY layer.
You can define the alpha, style and outline properties. Color is determined by the
DashboardResult and ColorMap parameters passed to the getLayerDrawingOptions function.
Implementation public function set polySymbol(value:SimpleFillSymbol):voidSee also

public function getLayerDrawingOptions(dashboardResult:DashboardResult, colorMap:Object = null, useDefaultColorForMissingValues:Boolean = false, responder:IResponder = null):void
Creates LayerDrawingOptions for the reviewer map server's REVTABLEPOINT, REVTABLELINE, and REVTABLEPOLY layers.
Parameters
| dashboardResult:DashboardResult — Obtained from a query to Data Reviewer Server using the DashboardTask.getDashboardResult function.

ReturnsEvent Object Type: mx.rpc.events.FaultEvent
Dispatched when there is a problem accessing the Reviewer Map Server.
Event Object Type: com.esri.drs.DataReviewerTaskEventDataReviewerTaskEvent.type property = com.esri.drs.DataReviewerTaskEvent.GET_LAYER_DRAWING_OPTIONS_COMPLETE
Dispatched when the after the getLayerDrawingOptions operation successfully completes.
The event result object contains two properties:
