Member Function Documentation
ItemResourceCache::ItemResourceCache (const QString &path, QObject *parent = nullptr)
Constructor that takes a path to the item resource cache, and an optional parent object.
[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.
[signal] void ItemResourceCache::loadStatusChanged (Esri::ArcGISRuntime::LoadStatus loadStatus )
loadStatus See Loadable.
[override virtual] ItemResourceCache::~ItemResourceCache ()
Destructor
[override virtual] void ItemResourceCache::cancelLoad ()
Reimplements: Loadable::cancelLoad().
See Loadable.
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().
See Loadable.
[override virtual] Esri::ArcGISRuntime::Error ItemResourceCache::loadError () const
Reimplements: Loadable::loadError() const.
See Loadable.
[override virtual] Esri::ArcGISRuntime::LoadStatus ItemResourceCache::loadStatus () const
Reimplements: Loadable::loadStatus() const.
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().
See Loadable.
