    Detailed Description

    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 the GenerateOfflineMapParameterOverrides with an instance of an 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::generateGeodatabaseParameters, GenerateOfflineMapParameterOverrides::exportVectorTilesParameters, GenerateOfflineMapParameterOverrides::exportTileCacheParameters. The particular dictionary property will be determined by the type property.

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

    OfflineMapParametersKey::OfflineMapParametersKey(Esri::ArcGISRuntime::OfflineMapParametersKey &&other)

    Move operator from other OfflineMapParametersKey.

    OfflineMapParametersKey::OfflineMapParametersKey(const Esri::ArcGISRuntime::OfflineMapParametersKey &other)

    Copy constructor from other OfflineMapParametersKey.

    OfflineMapParametersKey::OfflineMapParametersKey(Esri::ArcGISRuntime::UtilityNetwork *utilityNetwork)

    Create an offline map parameters key for the specified UtilityNetwork.

    A UtilityNetwork with a URL that points to a feature service, supports offline use when it returns true for SyncCapabilities::isSupportsUtilityNetworkSystem.

    The returned key can be used to retrieve a data-type-specific parameter object from the dictionary returned by GenerateOfflineMapParameterOverrides::generateGeodatabaseParameters

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

    This function was introduced in Esri::ArcGISRuntime 100.11.

    OfflineMapParametersKey::OfflineMapParametersKey(Esri::ArcGISRuntime::ServiceFeatureTable *table)

    Create an offline map parameters key for the given table.

    The returned key can be used to retrieve a data type specific parameters object from the dictionary returned by GenerateOfflineMapParameterOverrides::generateGeodatabaseParameters.

    If the table is not supported, the constructed key will return true for the isEmpty property and the keyError property will provide details of the problem.

    OfflineMapParametersKey::OfflineMapParametersKey(Esri::ArcGISRuntime::Layer *layer)

    Create an offline map parameters key for the given layer.

    Layers that are supported for offline use are:

    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 type property:

    If the layer type is not supported, the constructed key will return true for the isEmpty property and the keyError property will provide details of the problem.

    OfflineMapParametersKey::OfflineMapParametersKey()

    Constructor.

    This constructor create an empty (invalid) key - see isEmpty. You should use the constructors accepting a layer or table instead.

    Esri::ArcGISRuntime::OfflineMapParametersKey &OfflineMapParametersKey::operator=(Esri::ArcGISRuntime::OfflineMapParametersKey &&other)

    Move operator from other OfflineMapParametersKey.

    Esri::ArcGISRuntime::OfflineMapParametersKey &OfflineMapParametersKey::operator=(const Esri::ArcGISRuntime::OfflineMapParametersKey &other)

    Assignment operator from other OfflineMapParametersKey.

    OfflineMapParametersKey::~OfflineMapParametersKey()

    Destructor.

    bool OfflineMapParametersKey::isEmpty() const

    Returns whether this is a valid key object.

    Returns true when the key does not correspond to a valid set of parameters for taking a layer or table offline.

    Esri::ArcGISRuntime::Error OfflineMapParametersKey::keyError() const

    Returns an error describing any problems when creating this key object.

    If there were no issues, the error will be empty.

    QUrl OfflineMapParametersKey::serviceUrl() const

    Returns the service URL of this key.

    The service URL is the URL associated with a data specific parameter object in one of the dictionaries owned by a GenerateOfflineMapParameterOverrides instance.

    Esri::ArcGISRuntime::OfflineMapParametersType OfflineMapParametersKey::type() const

    Returns the type of parameters object used to take layers offline.

    The type of this key indicates which parameters dictionary this key belongs to:

    See also OfflineMapParametersType.

    bool OfflineMapParametersKey::operator<(const Esri::ArcGISRuntime::OfflineMapParametersKey &other) const

    Less than operator for other OfflineMapParametersKey.

    Returns true when this OfflineMapParametersKey is less than the other.

    bool OfflineMapParametersKey::operator==(const Esri::ArcGISRuntime::OfflineMapParametersKey &other) const

    Comparison operator with other OfflineMapParametersKey.

    Returns true when the two are equivalent.
