Class GeotriggersInfo

java.lang.Object
com.esri.arcgisruntime.geotriggers.GeotriggersInfo
All Implemented Interfaces:
Loadable
public class GeotriggersInfo extends Object implements Loadable
Presents information on a set of Geotrigger objects defined for a GeoModel.

The author of an ArcGISMap or an ArcGISScene can optionally specify one or more Geotrigger conditions to be monitored when using the data. Once this type is loaded, review the list of getGeotriggers() and create a GeotriggerMonitor to monitor each.

When a Geotrigger is defined with a GeotriggerFeed of type LocationGeotriggerFeed, you must supply a LocationDataSource to provide your device location. The general workflow is as follows:

Geotriggers can also take into account floors within buildings. If the GeotriggersInfo is defined as part of a GeoModel that includes a valid GeoModelFloorDefinition, then the list of GeotriggersInfo.getGeotriggers() can take floor information into account. All layers and tables that are used by the floor definition are loaded when a floor aware GeotriggerMonitor is started. To take floors into account when monitoring geotriggers, use a LocationDataSource that includes floor details.

    • getGeotriggers

      public List<Geotrigger> getGeotriggers()
      Gets the set of Geotrigger objects defined for a GeoModel.

      This list is populated with Geotrigger conditions defined by the author of the map or scene when the GeotriggersInfo is LoadStatus.LOADED. If no geotriggers are defined, this list will remain empty.

      You can add your own geotriggers to this property but be aware that when you save the map or scene any Geotrigger objects that reference local data (for example a GraphicsOverlayFenceParameters) will be omitted.

      Returns:
      the set of Geotrigger objects defined for a GeoModel

    • cancelLoad

      public void cancelLoad()
      Description copied from interface: Loadable
      Cancels loading metadata for the object.

      Cancels loading the metadata if the object is loading, and always invokes the done loading listener.

      A load operation that is in progress (LoadStatus.LOADING state) can be cancelled by calling this method and the resource will transition from LoadStatus.LOADING to LoadStatus.FAILED_TO_LOAD state. If the load operation was successfully cancelled, a CancellationException will be returned from Loadable.getLoadError().

      Cancellation should be used carefully because all enqueued done loading listeners for that resource instance will get invoked with an error stating that the operation was cancelled. Thus, one component in the application can cancel the load operation initiated by other components.

      This method does nothing if the resource is not in LoadStatus.LOADING state.

      Specified by:
      cancelLoad in interface Loadable

    • loadAsync

      public void loadAsync()
      Description copied from interface: Loadable
      Loads the metadata of the loadable resource asynchronously.

      The load status changes from LoadStatus.NOT_LOADED to LoadStatus.LOADING. A listener can be added via Loadable.addDoneLoadingListener(java.lang.Runnable) that is invoked upon completion of the asynchronous load operation.

      If the load operation completes successfully, the load status will be LoadStatus.LOADED, which means the resource has loaded its metadata.

      If the load operation failed, the load status will be LoadStatus.FAILED_TO_LOAD and the error can be retrieved by calling Loadable.getLoadError().

      This method can be called concurrently and repeatedly, but only one attempt is ever made to perform the load operation. If a load operation is already in progress (LoadStatus.LOADING state) when loadAsync is called, it simply piggy-backs on the outstanding operation and the done loading listener added to the loadable resource is enqueued to be invoked when that operation completes. If the operation has already completed (LoadStatus.LOADED or LoadStatus.FAILED_TO_LOAD state) when loadAsync is called, the done loading listener is immediately invoked when added to the loadable resource.

      If a loadable resource has failed to load, calling loadAsync on it subsequently will not change its state. The done loading listener will be invoked immediately when added to the loadable resource. In order to retry loading the resource, Loadable.retryLoadAsync() needs to be used.

      A load operation that is in progress (LoadStatus.LOADING state) can be cancelled by calling Loadable.cancelLoad().

      Specified by:
      loadAsync in interface Loadable

    • retryLoadAsync

      public void retryLoadAsync()
      Description copied from interface: Loadable
      Loads or retries loading metadata for the object asynchronously.

      Will retry loading the metadata if the object's load status is LoadStatus.FAILED_TO_LOAD. Will load the object if it is not loaded. Will not retry to load the object if the object is loaded.

      For more details on the load process see Loadable.loadAsync().

      Specified by:
      retryLoadAsync in interface Loadable

    • addDoneLoadingListener

      public void addDoneLoadingListener(Runnable runner)
      Description copied from interface: Loadable
      Adds a listener to the loadable resource that is invoked when loading has completed.

      The listener may be added at any point, whether the loadable resource has already completed loading or not.

      • For resources that are not loaded when the listener is added (LoadStatus is NOT_LOADED or LOADING): When the resource completes loading, the listener will be invoked on the UI thread if it is added from the UI thread, otherwise it is not guaranteed on which thread the listener is invoked.
      • For resources that are already loaded when the listener is added (LoadStatus is LOADED or FAILED_TO_LOAD): The listener will be called immediately, on the current thread.

      Alternatively, to be notified when there is any change in the load status, add a listener to the Loadable.loadStatusProperty() instead.

      Specified by:
      addDoneLoadingListener in interface Loadable
      Parameters:
      runner - a Runnable that is invoked upon completion of the load operation

    • removeDoneLoadingListener

      public boolean removeDoneLoadingListener(Runnable runner)
      Description copied from interface: Loadable
      Removes a done loading listener from the loadable resource.
      Specified by:
      removeDoneLoadingListener in interface Loadable
      Parameters:
      runner - the listener to be removed
      Returns:
      true if the listener was removed, otherwise false

    • addLoadStatusChangedListener

      public void addLoadStatusChangedListener(LoadStatusChangedListener listener)
      Description copied from interface: Loadable
      Adds a LoadStatusChangedListener to the loadable resource that is invoked whenever the load status changes.

      Adding this listener on the UI thread will cause it to be invoked on the UI thread, otherwise it is not guaranteed on which thread the listener is invoked.

      The listener will not be called if added to a loadable resource that has already completed loading. To be notified when a loadable resource has completed loading, including if the resource is already loaded when the listener is added, use the Loadable.addDoneLoadingListener(Runnable) method.

      Specified by:
      addLoadStatusChangedListener in interface Loadable
      Parameters:
      listener - the LoadStatusChangedListener to be added

    • removeLoadStatusChangedListener

      public boolean removeLoadStatusChangedListener(LoadStatusChangedListener listener)
      Description copied from interface: Loadable

      Specified by:
      removeLoadStatusChangedListener in interface Loadable
      Parameters:
      listener - the LoadStatusChangedListener to be removed
      Returns:
      true if the listener was removed, otherwise false
