Method PopulateFromServiceAsync
PopulateFromServiceAsync(QueryParameters, Boolean, IEnumerable<String>)
Asynchronously populates the OGC API - Features feature collection table with the results of a query.
Declaration
public Task<FeatureQueryResult> PopulateFromServiceAsync(QueryParameters parameters, bool clearCache, IEnumerable<string> outFields)Parameters
| Type | Name | Description |
|---|---|---|
| QueryParameters | parameters | The QueryParameters used to filter feature results. |
| System.Boolean | clearCache | A value indicating whether to clear existing table data before loading new results. If |
| System.Collections.Generic.IEnumerable<System.String> | outFields | The optional list of attribute fields to include in the result. |
Returns
| Type | Description |
|---|---|
| System.Threading.Tasks.Task<FeatureQueryResult> | A System.Threading.Tasks.Task that represents the asynchronous populate from service operation. The value of the task result is a FeatureQueryResult object. |
Remarks
Use the default (empty) QueryParameters to get all features from a service.
Specifying null or an empty enumerable for outFields will result in the
default set of outfields being used. Spatial queries (those that set
Geometry) must use Intersects.
