      • refreshObjectId

        @Deprecated
public boolean refreshObjectId()
        Deprecated.
        As of 100.4.0, replaced by Feature.refresh().
        Updates both the object Id and global Id (if applicable) of the feature to get the permanent value after edits have been applied to the service with ServiceFeatureTable.applyEditsAsync().

        Note: Global Ids are assigned by the server and will always require calling this method to update the feature's attributes with the new value.

        Returns:
        true if the object Id and/or global Id was changed to a permanent Id, false if the Id was already a permanent value or none was available.
        Since:
        100.0.0

      • relateFeature

        public void relateFeature​(ArcGISFeature feature)
        Sets up a relationship between this feature and the provided feature.

        If this relationship is keyed on an object ID or global ID, and the origin feature in this call has been created locally, you must first call ServiceFeatureTable.applyEditsAsync() and refreshObjectId() to obtain the new object ID and global ID generated by the service. If this is not done, then the destination feature will end up referring to an outdated ID and will not be considered related.

        Parameters:
        feature - the feature to relate to
        Throws:
        IllegalArgumentException - if feature is null
        Since:
        100.1.0

      • relateFeature

        public void relateFeature​(ArcGISFeature feature,
                          RelationshipInfo relationshipInfo)
        Sets up a relationship between this feature and the provided feature based on the given relationship info.

        If this relationship is keyed on an object ID or global ID, and the origin feature in this call has been created locally, you must first call ServiceFeatureTable.applyEditsAsync() and refreshObjectId() to obtain the new object ID and global ID generated by the service. If this is not done, then the destination feature will end up referring to an outdated ID and will not be considered related.

        Parameters:
        feature - the feature to relate to
        relationshipInfo - the relationship info to use when relating the two features, can be null
        Throws:
        IllegalArgumentException - if feature is null
        Since:
        100.1.0

      • unrelateFeature

        public void unrelateFeature​(ArcGISFeature feature)
        Removes the relationship between this feature and the provided feature.
        Parameters:
        feature - the feature from which this feature should remove its relationship
        Throws:
        IllegalArgumentException - if feature is null
        Since:
        100.1.0

      • getLoadStatus

        public LoadStatus getLoadStatus()
        Description copied from interface: Loadable
        Returns the LoadStatus of the loadable resource.
        Specified by:
        getLoadStatus in interface Loadable
        Returns:
        the LoadStatus of the loadable resource

      • 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()
        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().

        An ArcGISFeature is loadable. Depending on a ServiceFeatureTable's feature request mode, queries on the table can return ArcGISFeature objects which have the minimum set of attributes required for rendering and labeling (and geometries do not include m values). For more details, see the following:

        To access all attributes in the returned ArcGISFeatures, call this method on each feature. For alternative ways to load all attributes in the returned features, see loadOrRefreshFeaturesAsync(Iterable<Feature>) or ServiceFeatureTable.queryFeaturesAsync(QueryParameters, ServiceFeatureTable.QueryFeatureFields)

        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, use the Loadable.addLoadStatusChangedListener(LoadStatusChangedListener) method 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

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

      • close

        public void close()
        Closes this ArcGISFeature, relinquishing any underlying resources. This method is invoked automatically on objects managed by the try-with-resources statement. Any method invoked on this ArcGISFeature instance after it has been closed throws an IllegalStateException. This method is idempotent, in other words it can be called more than once without any side effects.

        Calling this method is not mandatory, but recommended on Android if large amounts of ArcGISFeature instances are allocated, to ensure a deterministic and timely release of resources.

        Note that this method does not close the underlying geodatabase. For closing the geodatabase see Geodatabase.close().

        Specified by:
        close in interface AutoCloseable
