Enum QueryMode

java.lang.Object
  java.lang.Enum<QueryMode>
      com.esri.map.QueryMode

All Implemented Interfaces:

Serializable, Comparable<QueryMode>

public enum QueryMode
extends Enum<QueryMode>

A feature layer can work in three modes. By default, the layer works on Snapshot mode. You can change the mode before initializing the layer.

Enum Constant Summary

ON_DEMAND
In OnDemand mode, the feature layer retrieves features from the server when needed based on the following criteria : Features within the current spatial extent.

SELECTION_ONLY
In SelectionOnly mode, features are retrieved from the server only when they are selected.

SNAPSHOT
In Snapshot mode, the feature layer retrieves all the features from the associated layer resource and displays them as graphics on the client.

Method Summary

static QueryMode	valueOf(String name) Returns the enum constant of this type with the specified name.
static QueryMode[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

SNAPSHOT

public static final QueryMode SNAPSHOT

In Snapshot mode, the feature layer retrieves all the features from the associated layer resource and displays them as graphics on the client. Definition expressions are honored in this mode.

ON_DEMAND

public static final QueryMode ON_DEMAND

In OnDemand mode, the feature layer retrieves features from the server when needed based on the following criteria :

Features within the current spatial extent.

Features matching the definition expression.

SELECTION_ONLY

public static final QueryMode SELECTION_ONLY

In SelectionOnly mode, features are retrieved from the server only when they are selected. Features are available on the client only while they are selected. To work with selected features call the ArcGISFeatureLayer.selectFeatures(Query,SELECTION_METHOD,CallbackListener) method.

Method Detail

values

public static QueryMode[] 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 (QueryMode c : QueryMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static QueryMode valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
