    • getUpdateCapabilities

      public OfflineMapUpdateCapabilities getUpdateCapabilities()
      Gets a description of the methods used for obtaining updates to the offline map that was used to create this task.

      You can use this property to determine whether an offline map is configured to use the update packages (see OfflineMapUpdateCapabilities.isSupportsScheduledUpdatesForFeatures()) or to sync directly with feature services (see OfflineMapUpdateCapabilities.isSupportsSyncWithFeatureServices())). If the offline map was created using PreplannedUpdateMode.DOWNLOAD_SCHEDULED_UPDATES_AND_UPLOAD_NEW_FEATURES, it will support both update modes, but you will only be able to upload newly created features.

      Returns:
      the update capabilities, or null if this OfflineMapSyncTask is not loaded
      Since:
      100.6.0

    • checkForUpdatesAsync

      public ListenableFuture<OfflineMapUpdatesInfo> checkForUpdatesAsync()
      Executes an asynchronous operation to check what updates are available for the offline map that was used to construct this task. The result is an OfflineMapUpdatesInfo object that provides information on:
      • online changes that can be applied to update your offline map
      • local changes from your offline map that can be sent back to the online services
      Calling this method provides high-level information on the available updates. It can help you to determine whether to call syncOfflineMap(OfflineMapSyncParameters) immediately, based upon factors such as current disk space and network availability. Examine these properties before starting the potentially time-consuming offline map sync process.

      The resulting OfflineMapUpdatesInfo provides a snap-shot of available updates when this method was called. To check for new updates you need to call this method again.

      Returns:
      a ListenableFuture for tracking when the operation is done and getting the result; also allows cancellation
      Since:
      100.6.0

    • createDefaultOfflineMapSyncParametersAsync

      public ListenableFuture<OfflineMapSyncParameters> createDefaultOfflineMapSyncParametersAsync()
      Executes an asynchronous operation to create a set of default parameters that can be used to synchronize an offline map's geodatabases with their originating services. The result is an OfflineMapSyncParameters object.

      The parameters will be pre-populated with values appropriate for updating the feature data in this offline map.

      The default parameters will reflect the mobile geodatabases used by the offline map.

      Returns:
      a ListenableFuture for tracking when the operation is done and getting the result; also allows cancellation
      Since:
      100.6.0

    • syncOfflineMap

      public OfflineMapSyncJob syncOfflineMap(OfflineMapSyncParameters parameters)
      Creates an OfflineMapSyncJob that can be used to synchronize an offline map's geodatabases with their originating services.

      You should not execute more than one sync on a particular geodatabase at the same time. This includes any operations that export or import deltas from the local Geodatabase:

      Parameters:
      parameters - the parameters to be used to create the OfflineMapSyncJob
      Returns:
      the OfflineMapSyncJob; note you must call Job.start() to start the Job
      Throws:
      IllegalArgumentException - if parameters is null

    • getLoadStatus

      public LoadStatus getLoadStatus()
      Gets the value of the property loadStatus.
      Specified by:
      getLoadStatus in interface Loadable
      Property description:
      Returns:
      the LoadStatus of the loadable resource

    • getLoadError

      public ArcGISRuntimeException getLoadError()
      Gets the value of the property loadError.
      Specified by:
      getLoadError in interface Loadable
      Property description:
      Returns:
      the most recent error that was encountered when the loadable resource transitioned to the LoadStatus.FAILED_TO_LOAD state.

    • 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 listener)
      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:
      listener - a Runnable that is invoked upon completion of the load operation

    • removeDoneLoadingListener

      public boolean removeDoneLoadingListener(Runnable listener)
      Description copied from interface: Loadable
      Removes a done loading listener from the loadable resource.
      Specified by:
      removeDoneLoadingListener in interface Loadable
      Parameters:
      listener - 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

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