populateFromService method
- QueryParameters? parameters,
- required bool clearCache,
- required List<
String> outFields,
Populates the WFS feature table using the query parameters.
Use the default (empty) QueryParameters to get all features from the service. If you specify a null or an empty collection for outfields, then the default set of outfields are used.
WFS is compatible with a subset of possible queries defined by QueryParameters. The QueryParameters.whereClause only works when the table is backed by a service powered by a GeoServer. Spatial queries (those that specify geometries) must use the SpatialRelationship.intersects spatial relationship.
You must ensure that the WfsFeatureTable.featureRequestMode is set to FeatureRequestMode.manualCache before attempting to populate the table.
Parameters:
parameters
— Options for controlling the operation.clearCache
— If true, the existing table data is cleared before it is populated with the query result.outFields
— A List containing String.
Return Value: A Future that returns a FeatureQueryResult type.
