To return immediately if a cache lookup fails, use CacheOnly.Discover the native side of Android and inject the power of C/C++ in your applications Are you an Android Java programmer who needs more performance? Are you a C/C++ developer who doesn’t want to bother with the complexity of Java and its out-of-control garbage collector? Do you want to create fast intensive multimedia applications or games? If you’ve answered yes to any of these questions then this book is for you. To skip cache lookups and query the network right away, use OnlineOnly. (Default) To query network if the requested resource is not found in the cache, use OnlineIfNotFound. Olp ::client :: HRN (kCatalogHRN ), layer_id, version, client_settings ) Ĭreate the PartitionsRequest object with one of the following fetch options: Olp ::dataservice ::read ::VersionedLayerClient layer_client ( For the CacheOnly fetch option, only checks the cache. For the OnlineOnly fetch option, only queries the network. If the online version is higher than the cache version, the cache version is updated. For the OnlineIfNotFound fetch option, queries the network, and if an error occurs, checks the cache. Depending on the fetch option that you specified in your first API call to the client, the GetLatestVersion method automatically gets the latest version in one of the following ways: If you do not specify a catalog version, the latest version is used. Partition metadata consists of the following information about the partition:įor instructions, see Create platform client settings.ĭepending on the layer type, create a versioned or volatile layer client with the HERE Resource Name (HRN), layer ID, layer version, and platform client settings from step 1. ShouldRetry – returns true if this operation can be retried. GetMessage – returns a text description of the encountered error. GetHttpStatusCode – returns the HTTP response code. GetErrorCode – returns the ErrorCode value defined by the olp::client::ErrorCode enum. The ApiError class contains the following methods used to get details of the incurred error: GetNotifications – returns the catalog notification status. GetVersion – returns the current catalog version number. GetLayers – returns details of the layers contained in the catalog. GetCreated – returns the catalog creation time. GetBillingTags – returns the billing tags set on the catalog. GetTags – returns the catalog tags collection. GetOwner – returns the identity of the catalog owner.
