Detailed Description
For example, an ArcGIS vector tile layer can have style resources, such as fonts and sprites.
Member Function Documentation
[explicit] ItemResourceCache::ItemResourceCache (const QString &path, QObject *parent = nullptr)
Creates an instance of this object with a path to a directory containing ItemResourceCache.
- path - path.
- parent - The optional parent QObject.
[override virtual] ItemResourceCache::~ItemResourceCache ()
Destructor
[override virtual] void ItemResourceCache::cancelLoad ()
Reimplements: Loadable::cancelLoad().
Cancels loading metadata for the object.
Cancels loading the metadata if the object is loading.
See Loadable.
[signal] void ItemResourceCache::doneLoading (const Esri::ArcGISRuntime::Error &loadError )
Signal emitted when this object is done loading.
- loadError - Details about any error that may have occurred.
If there is a load error, it will also be emitted on the errorOccurred signal.
Esri::ArcGISRuntime::LocalItem *ItemResourceCache::item() const
Returns the local item containing this item resource cache's thumbnail and metadata.
This property can be a nullptr if the LocalItem is not present within the ItemResourceCache directory. If the ItemResourceCache was taken offline using ExportVectorTilesTask or OfflineMapTask, the LocalItem will be populated from the online PortalItem. If the ItemResourceCache was created inside a MobileMapPackage authored from ArcGIS Pro, then this property will return a nullptr.
[override virtual] void ItemResourceCache::load()
Reimplements: Loadable::load().
Loads the metadata for the object asynchronously.
Loads the metadata if the object is not loaded.
See Loadable.
[override virtual] Esri::ArcGISRuntime::Error ItemResourceCache::loadError () const
Reimplements: Loadable::loadError() const.
Returns the load error.
See Loadable.
See also Error.
[override virtual] Esri::ArcGISRuntime::LoadStatus ItemResourceCache::loadStatus () const
Reimplements: Loadable::loadStatus() const.
Returns the load status.
See Loadable.
See also LoadStatus.
[signal] void ItemResourceCache::loadStatusChanged (Esri::ArcGISRuntime::LoadStatus loadStatus )
loadStatus See Loadable.
QString ItemResourceCache::path() const
Returns the path to the on-disk location containing this item resource cache.
The path can be a directory on disk that contains the ItemResourceCache. Alternatively, if the ItemResourceCache was loaded from a package file, such as a MobileMapPackage, the path is to the package.
[override virtual] void ItemResourceCache::retryLoad ()
Reimplements: Loadable::retryLoad().
Loads or retries loading metadata for the object asynchronously.
Will retry loading the metadata if the object is failed to load. Will load the object if it is not loaded. Will not retry to load the object if the object is loaded. Will always call the done loading if this is called.
See Loadable.
