The layer's capabilities.editing.supportsRollbackOnFailure property must be true if using this parameter. Applications can access and display feature layers that are hosted on ArcGIS Online or ArcGIS Enterprise.A hosted feature layer contains features (records) with a geometry and a set of attributes. This object can be either pre-uploaded data or base 64 encoded data. When creating a FeatureLayer from client-side features, the objectId field must be set either in the fields array or via objectIdField. Diese Feature-Classes sind häufig in einer Geodatabase enthalten. Fires after the layer's LayerView is created and rendered in a view. javascript arcgis esri arcgis-js-api. // the first layer in the service is returned, // Set hostname when using an on-premise portal (default is ArcGIS Online).

Indicates if the layer supports REST API queryAttachments operation, which is supported with hosted feature services at version 10.5 and greater. The imagery layer that contains land cover classification rasters. Indicates if the query response supports pagination. Object containing features and attachments to be added, updated or deleted. If it is fulfilled, true will be returned. See the documentation for Renderer and the Creating visualizations manually guide for more information about the various visualization options for Feature Layers. Indicates if the layer supports field-based statistical functions. For a layer to be visible in a view, it must be added to the Map referenced by the view. Only the features that satisfy the definition expression are displayed in the View. Fires after the layer's LayerView is destroyed and no longer renders in a view. Indicates if the layer's query response includes the extent of features. This is valid only for hosted feature services. Für Feature-Layer können Daten aus jeder Quelle verwendet werden, die Punkt-, Polylinien-, Polygon-, Multipoint- oder Multipatch-Vektor-Feature-Daten liefert. Specifies the attributes and spatial filter of the query. Very large datasets may require potentially long initial load times, particularly at small scales. Key in this case is the. HTML form that contains a file upload field pointing to the file to be added as an attachment. Use supportsAdd, supportsUpdate and supportsDelete to determine which editing operations are supported. Requires ArcGIS Server service 10.1 or greater. Example: The service has a horizontal spatial reference using feet units and the query is made with outSpatialReference based on meter units, then queryFeatures() automatically converts the values from feet to meter units. This property is required when constructing a FeatureLayer from a collection of client-side features. I have tried the following: options { ... where: whereClause } new FeatureLayer(url, options); The above does not work. The editor tracking fields, which record who adds or edits the data through the feature service and when edits are made. When false, the layer may still be added to a Map instance that is referenced in a view, but its features will not be visible in the view. Sample: Add multiple label classes to a layer, Sample: Flat vs. volumetric 3D symbol layers. Indicates whether to display the Attachments field in the table. The minimum scale (most zoomed out) at which the layer is visible in the view. Properties, i.e. Can be thought of as the opposite of, Colors in top and background layers are multiplied by their alphas (layer, Colors in top and background layers are added together. The right image shows when the overlay blend mode is applied to the buffer graphics layer. This is only applicable if the feature layer supports attachments. This value gets updated every time the layer's data is edited or when any of its properties change. Requires ArcGIS Server service 10.3 or greater. Indicates if m-values must be provided when updating features. Requires ArcGIS Server service 10.1 or greater. The color-burn mode works well with colorful top and background layers since it increases saturation in mid-tones. A value of 0 means the layer does not have a maximum scale. Array of Chart Items of type WebMapWebChart available on the feature layer. The invert blend mode inverts the layer similar to a photographic negative. The following screenshots show where the topo layer is blended with world hillshade layer with luminosity blend mode. Creates a brighter effect by decreasing the contrast between the top and background layers, resulting in saturated mid-tones and bright highlights. The maximum scale (most zoomed in) at which the layer is visible in the view. See the object specification table below for the required properties of this object. If it is rejected, true will be returned. Called by the views, such as MapView and SceneView, when the layer is added to the Map.layers collection and a layer view must be created for it. Black in the top layer will stay unchanged. If both view and layer time extents are set while this property is true, then the features that fall within the intersection of the view and layer time extents will be displayed. Specifies how features are placed on the vertical axis (z). Sample - Point clustering with visual variables. // Queries for the extent of all features matching the layer's configurations, // go to the extent of the results satisfying the query, // Queries for the count of all features matching the layer's configurations, // prints the number of results satisfying the query, // Queries for all the features matching the layer's configurations, // prints the array of features to the console, // query all features from the layer and only return, // Queries for all the Object IDs of features matching the layer's configurations, // prints the array of Object IDs to the console, // query related features for given objectIds, // print out the attributes of related features if the result, // is returned for the specified objectId, // Although this example uses MapView, any class instance that is a promise may use when() in the same way, // This function will execute once the promise is resolved, // This function will execute if the promise is rejected due to an error, // This function will fire each time applyEdits() is completed successfully, // This function will fire each time a layer view is created for this, // The LayerView for the layer that emitted this event, // This function fires when an error occurs during the creation of the layer's layerview, "LayerView failed to create for layer with the id: ", create a FeatureLayer with client-side graphics sample, add or remove graphics from a FeatureLayer sample, capabilities.editing.supportsRollbackOnFailure, capabilities.operations.supportsQueryAttachments. The globalId of the attachment to be added or updated. // The form is defined as below in the html. Loads the resources referenced by this class. isResolved() may be used to verify if creating an instance of the class is resolved. Indicates whether the client-side features in the layer have M (measurement) values. It sets the query parameter's outFields property to ["*"]. The spatial reference of the layer.
