Class OfflineMapParametersKey

java.lang.Object

com.esri.arcgisruntime.tasks.offlinemap.OfflineMapParametersKey

public final class OfflineMapParametersKey
extends Object

Represents a key comprised of a service URL and a type of an online service. The key is used to lookup values in a dictionary exposed by a GenerateOfflineMapParameterOverrides.

GenerateOfflineMapParameterOverrides consist of instances of data type specific parameters GenerateGeodatabaseParameters, ExportTileCacheParameters and ExportVectorTilesParameters.

Each instance is associated with the service URL that the parameters will be sent to when taking the given data offline. The data type specific parameters can be retrieved from their respective dictionaries on GenerateOfflineMapParameterOverrides with an instance of OfflineMapParametersKey.

A key instance for a particular layer can be constructed by calling OfflineMapParametersKey(Layer). For a table, call OfflineMapParametersKey(ServiceFeatureTable). For a utility network, call OfflineMapParametersKey(UtilityNetwork).

Use the key with the dictionary returned by one of these properties: GenerateOfflineMapParameterOverrides.getGenerateGeodatabaseParameters(), GenerateOfflineMapParameterOverrides.getExportVectorTilesParameters(), GenerateOfflineMapParameterOverrides.getExportTileCacheParameters(). The particular dictionary property will be determined by the getType() property.

Note that a given parameters key/value pair may be shared by multiple layers in the map: for example a single com.esri.arcgisruntime.tasks.geodatabase.GenerateGeodatabaseParameters could represent the online settings for multiple feature layers and tables which all access the same underlying feature service.

Constructor Detail

OfflineMapParametersKey

public OfflineMapParametersKey(Layer layer)

Creates an OfflineMapParametersKey for the given layer.

Layers that are supported for offline use are:

• FeatureLayer with a table which is a ServiceFeatureTable.
• ArcGISTiledLayer with an online URL.
• ArcGISVectorTiledLayer with an online URL.

To construct a key the layer must be loaded, or if not loaded have a service URL available in the layer's properties. The returned key can be used to retrieve a data type specific parameters object from one of the three parameter overrides dictionaries. The dictionary that the key is valid for is indicated by its getType() property:

Parameter Type	Dictionary
GENERATE_GEODATABASE	GenerateOfflineMapParameterOverrides.getGenerateGeodatabaseParameters()
EXPORT_TILE_CACHE	GenerateOfflineMapParameterOverrides.getExportTileCacheParameters()
EXPORT_VECTOR_TILES	GenerateOfflineMapParameterOverrides.getExportVectorTilesParameters()

Parameters:

layer - a layer that is to be used to access dictionaries in a GenerateOfflineMapParameterOverrides object

Throws:

IllegalArgumentException - if layer is null

Since:

100.4.0

OfflineMapParametersKey

public OfflineMapParametersKey(ServiceFeatureTable serviceFeatureTable)

Creates an OfflineMapParametersKey for the given ServiceFeatureTable.

Parameters:

serviceFeatureTable - a table that is to be used to access dictionaries in a GenerateOfflineMapParameterOverrides object

Throws:

IllegalArgumentException - if serviceFeatureTable is null

Since:

100.4.0

OfflineMapParametersKey

public OfflineMapParametersKey(UtilityNetwork utilityNetwork)

Create an offline map parameters key for the specified UtilityNetwork.

An UtilityNetwork with URI that points to a feature service which returns true for SyncCapabilities.isSupportsUtilityNetworkSystem() is supported for offline use.

The returned key can be used to retrieve a data type specific parameter object from the dictionary returned by GenerateOfflineMapParameterOverrides.getGenerateGeodatabaseParameters()

If the UtilityNetwork does not support taking Utility Network data offline, an error is returned with a null handle.

Parameters:

utilityNetwork - UtilityNetwork that is to be used to access dictionaries in GenerateOfflineMapParameterOverrides object

Throws:

IllegalArgumentException - if utilityNetwork is null

Since:

100.11.0

Method Detail

getServiceUrl

public String getServiceUrl()

Gets service URL of this key. This is the URL associated with a data specific parameter object in one of the dictionaries owned by an GenerateOfflineMapParameterOverrides instance.

Returns:

getType

public OfflineMapParametersKey.Type getType()

Gets the parameter type of this key. This indicates which GenerateOfflineMapParameterOverrides dictionary this key belongs to:

Parameter Type	Dictionary
GENERATE_GEODATABASE	GenerateOfflineMapParameterOverrides.getGenerateGeodatabaseParameters()
EXPORT_TILE_CACHE	GenerateOfflineMapParameterOverrides.getExportTileCacheParameters()
EXPORT_VECTOR_TILES	GenerateOfflineMapParameterOverrides.getExportVectorTilesParameters()

Returns:

the parameter type
