public abstract class FeatureTable extends java.lang.Object implements Loadable, PopupSource
Represents a table ofFeature
s.A table defines a set of
Field
s, aGeometryType
and aSpatialReference
. FeatureTable can also represent non-spatial data that has no GeomeryType or SpatialReference. FeatureTables have a fixed schema.FeatureTable provides
queryFeaturesAsync(com.esri.arcgisruntime.data.QueryParameters)
for spatial and attribute querying, and methods to add, update, and delete features.Create instances of FeatureTable's subclasses using their constructors. A FeatureTable is used to create a
FeatureLayer
. The FeatureLayer, when added to a map, will display the table's features in the map.- Since:

Method Detail
-
getExtent
public Envelope getExtent()
Gets the geographic extent of features within the table.This is calculated differently for specific types and modes of feature tables.
For
ServiceFeatureTable
this can be used to determine the extent within which data can be edited. ServiceFeatureTables in manual cache mode will return the extent of the features which have been cached. All other modes will return the extent of the layer/table defined by the service (fromArcGISFeatureLayerInfo.getExtent()
).For GeodatabaseFeatureTables this returns the extent of the features which have been cached; this extent can grow as features are added or edited, but not shrink.

getLoadError
public ArcGISRuntimeException getLoadError()
Description copied from interface:Loadable
Returns the most recent error that was encountered when the loadable resource transitioned to theLoadStatus.FAILED_TO_LOAD
state, either due to calling theLoadable.loadAsync()
orLoadable.retryLoadAsync()
method.If the resource subsequently transitions to
LoadStatus.LOADED
(for example, if a call toretryLoadAsync
completes successfully) the error is cleared out.- Specified by:
getLoadError
in interfaceLoadable
- Returns:
- the most recent error that was encountered when the loadable resource transitioned to the
LoadStatus.FAILED_TO_LOAD
state.
-
getLoadStatus
public LoadStatus getLoadStatus()
Description copied from interface:Loadable
Returns theLoadStatus
of the loadable resource.- Specified by:
getLoadStatus
in interfaceLoadable
- Returns:
- the LoadStatus of the loadable resource
-
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
toLoadStatus.LOADING
. A listener can be added viaLoadable.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 callingLoadable.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) whenloadAsync
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
orLoadStatus.FAILED_TO_LOAD
state) whenloadAsync
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 callingLoadable.cancelLoad()
.
-
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 interfaceLoadable
-
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 fromLoadStatus.LOADING
toLoadStatus.FAILED_TO_LOAD
state. If the load operation was successfully cancelled, a CancellationException will be returned fromLoadable.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 interfaceLoadable
-
addDoneLoadingListener
public void addDoneLoadingListener(java.lang.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 interfaceLoadable
- Parameters:
listener
- a Runnable that is invoked upon completion of the load operation
-
removeDoneLoadingListener
public boolean removeDoneLoadingListener(java.lang.Runnable listener)
Description copied from interface:Loadable
Removes a done loading listener from the loadable resource.- Specified by:
removeDoneLoadingListener
in interfaceLoadable
- Parameters:
listener
- the listener to be removed- Returns:
- true if the listener was removed, otherwise false
-
onDoneLoadingInternal
protected void onDoneLoadingInternal()
-
addLoadStatusChangedListener
public void addLoadStatusChangedListener(LoadStatusChangedListener listener)
Description copied from interface:Loadable
Adds aLoadStatusChangedListener
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 interfaceLoadable
- Parameters:
listener
- theLoadStatusChangedListener
to be added
-
removeLoadStatusChangedListener
public boolean removeLoadStatusChangedListener(LoadStatusChangedListener listener)
