The IWMDMStorage4 interface extends IWMDMStorage3 by providing methods for retrieving a subset of available metadata for a storage, and for setting and retrieving a list of references to other storages.
Inheritance
The IWMDMStorage4 interface inherits from IWMDMStorage3. IWMDMStorage4 also has these types of members:
Methods
The IWMDMStorage4 interface has these methods.
| IWMDMStorage4::FindStorage The FindStorage method retrieves a storage in the current root storage, based on its persistent unique identifier. |
| IWMDMStorage4::GetParent The GetParent method retrieves the parent of the storage. |
| IWMDMStorage4::GetReferences The GetReferences method retrieves an array of pointers to IWMDMStorage objects pointed to by this storage. An abstract album or playlist is typically stored as a collection of references on an MTP device. |
| IWMDMStorage4::GetRightsWithProgress The GetRightsWithProgress method retrieves the rights information for the storage object, providing a callback mechanism for monitoring progress. |
| IWMDMStorage4::GetSpecifiedMetadata The GetSpecifiedMetadata method retrieves one or more specific metadata properties from the storage. |
| IWMDMStorage4::SetReferences The SetReferences method sets the references contained in a storage that has references (such as a playlist or album), overwriting any previously existing references held by the storage. |
