FeatureCollection QML Type

The item used to create this FeatureCollection.

Note that this property can only be changed or assigned before the FeatureCollection is loaded with layers.

See also Loadable.

JSON that can be used to instantiate the type instance.

Returns the load error (read-only).

Note: load errors are also reported on the error property and emit the errorChanged signal.

See also Loadable.

The Enums.LoadStatus of the Layer.

See also Loadable and Enums.LoadStatus.

The save status of one of the asynchronous save operations:

• save
• saveAs

Check this status when the saveStatusChanged signal emits.

This property was introduced in Esri.ArcGISRuntime 100.1.

See also Enums.TaskStatus.

Returns the list model of tables in this FeatureCollection (read-only).

See also FeatureCollectionTable.

Returns unknown JSON data from the source JSON. (read-only).

Unknown JSON data consists of values that are in the source JSON but not parsed by ArcGIS Runtime.

Returns unsupported JSON data from the source JSON. (read-only).

Unsupported JSON data consists of values that are supported by web maps, but are not exposed through the ArcGIS Runtime API.

Emitted when the item property changes.

Note: The corresponding handler is onItemChanged.

Emitted when the loadError property changes.

Note: load errors are also reported on the error property and emit the errorChanged signal.

Note: The corresponding handler is onLoadErrorChanged.

See also Loadable and Object.

Emitted when the loadStatus property changes.

Note: The corresponding handler is onLoadStatusChanged.

See also Loadable.

Emitted when the saveStatus property of this FeatureCollection changes.

Note: The corresponding handler is onSaveStatusChanged.

This signal was introduced in Esri.ArcGISRuntime 100.1.

Saves any changes that have been made to the FeatureCollection to the associated PortalItem.

The FeatureCollection must have been constructed using the PortalItem constructor to associate it with a PortalItem object, or must have been previously saved using saveAs.

Updates the FeatureCollection content data on the portal and also updates the portal item properties stored on the portal to match those stored within the FeatureCollection's PortalItem object.

If the portal associated with the item is not loaded, it will be loaded automatically. If the portal requires a credential that has not been supplied, it should be loaded before calling this function.

The FeatureCollection must be loaded to call this function. Calling this function will not force the FeatureCollection to start loading. If the FeatureCollection is not already associated with a PortalItem, calling save will emit loadErrorChanged.

The saveStatus property shows the progress of a save operation.

This method was introduced in Esri.ArcGISRuntime 100.1.

Saves the FeatureCollection to a new PortalItem.

• portal - The portal to save the PortalItem to.
• title - A title for the FeatureCollection.
• tags - A list of tags to associate with the FeatureCollection.
• folder - An optional PortalFolder belonging to the current user in which to save the FeatureCollection. If not specified the FeatureCollection will be saved in the user's root folder.
• description - An optional description for the FeatureCollection.
• localThumbnailImage - Optional thumbnail image which is converted into bytes.

The FeatureCollection does not need to be associated with an existing PortalItem object. Updates the FeatureCollection content data on the portal, and updates the portal item properties stored on the portal to match those stored within the FeatureCollection's PortalItem object.

The FeatureCollection must be loaded to call this function. Calling this function will not force the FeatureCollection to start loading.

Note: If the FeatureCollection was already associated with a PortalItem object (either because the FeatureCollection was created using a PortalItem or was previously saved), that object will be replaced with a new PortalItem, effectively duplicating the FeatureCollection on the portal.

The saveStatus property shows the progress of a saveAs operation.

This method was introduced in Esri.ArcGISRuntime 100.1.
