The QLandmarkCategoryFetchByIdRequest class allows a client to asynchronously request a list of categories by ID from a landmark manager.
The categories fetched by the manager should have a one-to-one correspondence to the IDs passed into this class. That is, the nth category in the returned list should have an ID which is equal to the nth ID in the list of IDs. Any invalid ID should correspond to an empty QLandmarkCategory.
For a QLandmarkCategoryFetchByIdRequest, the resultsAvailable() signal will be emitted as resultant categories are found (these are retrievable by calling categories()), whenever individual items error out(individual errors may be retrieved by calling errorMap()), as well as if an overall operation error occurred(which may be retrieved by calling QLandmarkAbstractRequest::error()).
Please see the class documentation for QLandmarkAbstractRequest for more information about he usage of request classes and ownership semantics.
