Constructor Details
Creates a new TiledMapServiceLayer object. (Added at v3.6)
Options:
< |
Optional | Class attribute to set for the layer's node. |
< |
Optional | An array of objects that define areas where a tiled map service should not display tiles. Each exclusion area object has the following properties:
min/maxZoom take precedence over min/maxScale. The value for geometry is of type Extent. Other geometry types might be supported in the future but are not currently supported. Geometry must be in the same spatial reference as the map. The exception is that a geographic extent (WGS84) can be used with web mercator maps and vice versa. Example:
var exclusionAreas = [{
minScale: 40000,
maxScale: 9028,
geometry: new Extent(
13871520.850500003,
3910293.086000003,
14574034.873400003,
4686306.161399998,
new SpatialReference(102100)
)
}];
Added at v3.10 |
< |
Optional | Refresh interval of the layer in minutes. Non-zero value sets up automatic layer refresh at the specified interval. |
< |
Optional | When true, tile resampling is enabled. It defaults to true if the service is part of the Esri basemaps. If not, it defaults to undefined until the layer is loaded, then to the value in the resourceInfo, otherwise it will be false. |
< |
Optional | Number of levels beyond the last level where tiles are available. If not specified, resampling is enabled at all levels where tiles are not available. |
Property Details
<String
StringThe URL, when available, where the layer's attribution data is stored. (Added at v3.1)
<Credential
CredentialProvides credential information for the layer such as userid and token if the layer represents a resource that is secured with token-based authentication. This value is available after the layer has been loaded i.e.
layer.loaded is true. (Added at v2.5)<Extent
ExtentFull extent as defined by the map service.
<Boolean
BooleanWhen true, the layer has attribution data. Use the getAttributionData method to retrieve this data as JSON. (Added at v3.1)
Known values:
true | falseDefault value:
false<String
StringID assigned to the layer. If not assigned, esri.Map assigns value. By default, the ID of the layer is "layer" followed by a number. The ID can be user defined only in the layer constructor.
Sample:
- Setting the layer ID in the layer constructor.
require([ "esri/layers/ArcGISDynamicMapServiceLayer", ... ], function(ArcGISDynamicMapServiceLayer, ... ) { var population = new ArcGISDynamicMapServiceLayer("http://myserver/arcgis/rest/population/MapServer/Layers", {id:"population"}); ... }); - Setting the layer ID after a layer is initialized.
population.id = "population";
- Retrieving the layer ID.
function getMapLayers() { for (var j=0, jl=map.layerIds.length; j<jl; j++) { var currentLayer = map.getLayer(map.layerIds[j]); alert("id: " + currentLayer.id); } }
<Extent
ExtentInitial extent as defined by the map service.
<Error
ErrorSet if the layer failed to load. (Added at v3.9)
<Boolean
BooleanWhen the layer is loaded, the value becomes "true", and layer properties can be accessed. The onLoad event is also fired.
Known values:
true | false<Number
NumberMaximum visible scale for the layer. If the map is zoomed in beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a maximum scale. (Added at v3.1)
Default value:
0<Number
NumberMinimum visible scale for the layer. If the map is zoomed out beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a visible scale. (Added at v3.1)
Default value:
0<Number
NumberOpacity or transparency of layer. Values range from 0.0 to 1.0, where 0.0 is 100% transparent and 1.0 has no transparency.
Known values:
0.0 - 1.0Default value:
1.0<Number
NumberRefresh interval of the layer in minutes. Non-zero value indicates automatic layer refresh at the specified interval. Value of 0 indicates auto refresh is not enabled. (Added at v3.7)
<Boolean
BooleanWhen true, the layer's attribution is displayed on the map. (Added at v3.1)
Known values:
true | falseDefault value:
true<SpatialReference
SpatialReferenceThe spatial reference of the map service. See Projected Coordinate Systems and Geographic Coordinate Systems for the list of supported spatial references.
<Boolean
BooleanWhen true, the layer is suspended. A layer is considered to be suspended when one of the following is true:
- The layer is hidden.
- The layer is not visible at the current map scale.
- The layer is explicitly suspended by calling the
Layer.suspendmethod.
Known values:
true | false<String

Event Details
[ On Style Events | Connect Style Event ]
Fires when there is a problem retrieving a layer. Should be used in favor of onError. (Added at v3.5)
Event Object Properties:
< |
ArcGIS Server error message returned in a JavaScript error object. |
Fires after layer properties for the layer are successfully populated. This event must be successful before the layer can be added to the map. Should be used in favor of onLoad. (Added at v3.5)
Event Object Properties:
< |
The loaded layer. |
Fires when the layer opacity has been changed, and returns an object with the opacity value. Should be used in favor of onOpacityChange. (Added at v3.5)
Event Object Properties:
< |
Fires when the layer opacity (transparency) changes. A number property named opacity that indicates the new opacity. Values range from 0.0 to 1.0, where 0.0 is 100% transparent and 1.0 has no transparency. |
This event is fired when the layer's
refreshInterval is modified. (Added at v3.7)Fires when a layer's minScale and/or maxScale is changed. Should be used in favor of onScaleRangeChange. (Added at v3.5)
Fires when a layer's scale visibility changes. The scale visibility changes when a layer is initially visible and becomes invisible because the map scale does not intersect the layer's scale range or vice versa. Should be used in favor of onScaleVisibilityChange. (Added at v3.5)
Fires any time a layer has finished loading or updating itself.
For an ArcGISTiledMapServiceLayer,
the event fires when all required tiles have been retrieved and displayed. For an
ArcGISDynamicMapServiceLayer or
ArcGISImageServiceLayer, the event fires
when the map image has been retrieved and displayed. For a GraphicsLayer,
the event fires when all graphics have been redrawn after a pan or zoom.
Deprecated at v2.0. Use update-start and update-end instead. (Added at v3.6)
Fires when a layer has finished updating its content. It is the responsibility of the subclass to determine when this event is fired. Should be used in favor of onUpdateEnd. (Added at v3.5)
Event Object Properties:
< |
Optional argument. The error object is available when an error occurs during the update. |
Fires when a layer begins to update its content. It is the responsibility of the subclass to determine when this event is fired. Should be used in favor of onUpdateStart. (Added at v3.5)
Fires when the layer visibility has been changed, and returns an object with a Boolean visible property containing the new visibility value of the layer. Should be used in favor of onVisibilityChange. (Added at v3.5)
Event Object Properties:
< |
Fires when the layer visibility changes. A boolean property named visible indicates whether or not the layer is visible after visibility changed. |
