public static enum ServiceFeatureTable.FeatureRequestMode extends java.lang.Enum<ServiceFeatureTable.FeatureRequestMode>
The feature request mode for aServiceFeatureTable
. It determines (1) whether features are cached locally (for quicker access by map and scene layers) and (2) whether queries are performed on the local cache or on the server.- Since:
- 100.0.0

Enum Constant Summary
Enum Constants Enum Constant Description MANUAL_CACHE
The features are requested from the server by an explicit call topopulateFromServiceAsync(QueryParameters, boolean, Iterable<String>)
, which populates the local cache.ON_INTERACTION_CACHE
The features are requested from the server as they are needed, in response to user or developer interaction with the layer (pan, zoom).ON_INTERACTION_NO_CACHE
The features are always requested from the server and are never cached.UNDEFINED
The feature request mode is undefined.

UNDEFINED
public static final ServiceFeatureTable.FeatureRequestMode UNDEFINED
The feature request mode is undefined. The feature table has not been loaded and the mode has yet to be set.
-
MANUAL_CACHE
public static final ServiceFeatureTable.FeatureRequestMode MANUAL_CACHE
The features are requested from the server by an explicit call topopulateFromServiceAsync(QueryParameters, boolean, Iterable<String>)
, which populates the local cache. Queries performed on the table will be executed locally.In this mode, the features have all fields defined by the
Iterable<String>
you pass topopulateFromServiceAsync(QueryParameters, boolean, Iterable<String>)
.
-
ON_INTERACTION_CACHE
public static final ServiceFeatureTable.FeatureRequestMode ON_INTERACTION_CACHE
The features are requested from the server as they are needed, in response to user or developer interaction with the layer (pan, zoom). Features are cached in the local table for the duration of the session. Queries are executed on the local cache or (if requested features are not resident in the cache) on the server. This mode is the default.In this mode, features have a minimum set of attributes, and feature geometries have no m values even if m values are defined by the service. This is an optimization for faster rendering. To access all attributes or access geometries that contain m values, the features you get from a query must be loaded. You can load them yourself or request that the query method return them already loaded (see
ServiceFeatureTable.QueryFeatureFields.LOAD_ALL
. For more information, see the class description forServiceFeatureTable
.

ON_INTERACTION_NO_CACHE
public static final ServiceFeatureTable.FeatureRequestMode ON_INTERACTION_NO_CACHE
The features are always requested from the server and are never cached. This mode ensures that you are working against the latest data, but it has a high network bandwidth since it goes to the server for all interactions (pans, zooms, selects, or queries).In this mode, features have a minimum set of attributes, and feature geometries have no m values even if m values are defined by the service. This is an optimization for faster rendering. To access all attributes or access geometries that contain m values, the features you get from a query must be loaded. You can load them yourself or request that the query method return them already loaded (see
ServiceFeatureTable.QueryFeatureFields.LOAD_ALL
. For more information, see the class description forServiceFeatureTable

values
public static ServiceFeatureTable.FeatureRequestMode[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (ServiceFeatureTable.FeatureRequestMode c : ServiceFeatureTable.FeatureRequestMode.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static ServiceFeatureTable.FeatureRequestMode valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
