# OpenLayers.Layer.ArcGIS93Rest

Instances of OpenLayers.Layer.ArcGIS93Rest are used to display data from ESRI ArcGIS Server 9.3 (and up?) Mapping Services using the REST API. Create a new ArcGIS93Rest layer with the OpenLayers.Layer.ArcGIS93Rest constructor. More detail on the REST API is available at http://sampleserver1.arcgisonline.com/ArcGIS/SDK/REST/index.html ; specifically, the URL provided to this layer should be an export service URL: http://sampleserver1.arcgisonline.com/ArcGIS/SDK/REST/export.html

### Constants

### DEFAULT_PARAMS

{Object} Hashtable of default parameter key/value pairs

### Properties

### isBaseLayer

{Boolean} Default is true for ArcGIS93Rest layer

### Constructor

### OpenLayers.Layer.ArcGIS93Rest

Create a new ArcGIS93Rest layer object.

#### Example

>     var arcims = new OpenLayers.Layer.ArcGIS93Rest("MyName",
>                                        "http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StateCityHighway_USA/MapServer/export",
>                                        {
>                                          layers: "0,1,2"
>                                        });

#### Parameters

name | {String} A name for the layer
url | {String} Base url for the ArcGIS server REST service
options | {Object} An object with key/value pairs representing the options and option values.

#### Valid Options

format | {String} MIME type of desired image type.
layers | {String} Comma-separated list of layers to display.
srs | {String} Projection ID.

### Functions

### clone

> clone: function ( | obj | )

Create a clone of this layer

#### Returns

{OpenLayers.Layer.ArcGIS93Rest} An exact clone of this layer

### getURL

> getURL: function ( | bounds | )

Return an image url this layer.

#### Parameters

bounds | {OpenLayers.Bounds} A bounds representing the bbox for the request.

#### Returns

{String} A string with the map image’s url.

### setLayerFilter

> setLayerFilter: function ( | id,
> | queryDef | )

addTile creates a tile, initializes it, and adds it to the layer div.

#### Parameters

id | {String} The id of the layer to which the filter applies.
queryDef | {String} A sql-ish query filter, for more detail see the ESRI documentation at http://sampleserver1.arcgisonline.com/ArcGIS/SDK/REST/export.html

### clearLayerFilter

> clearLayerFilter: function ( | id | )

Clears layer filters, either from a specific layer, or all of them.

#### Parameters

id | {String} The id of the layer from which to remove any filter. If unspecified/blank, all filters will be removed.

### mergeNewParams

> mergeNewParams:function( | newParams | )

Catch changeParams and uppercase the new params to be merged in before calling changeParams on the super class.

Once params have been changed, the tiles will be reloaded with the new parameters.

#### Parameters

newParams | {Object} Hashtable of new params to use

> clone: function ( | obj | )

Create a clone of this layer

> getURL: function ( | bounds | )

Return an image url this layer.

> setLayerFilter: function ( | id,
> | queryDef | )

addTile creates a tile, initializes it, and adds it to the layer div.

> clearLayerFilter: function ( | id | )

Clears layer filters, either from a specific layer, or all of them.

> mergeNewParams:function( | newParams | )

Catch changeParams and uppercase the new params to be merged in before calling changeParams on the super class.
