\class QLandmarkManager
\brief The QLandmarkManager class provides an interface for storage
and retrieval of landmarks from a landmark store.
\since 1.1
\inmodule QtLocation
\ingroup landmarks-main
The QLandmarkManager is the starting class to use when working with landmarks.
It effectively represents a landmark datastore and it provides the synchronous operations for the
creation, retrieval, updating and deletion of both landmarks and categories. For asynchronous operations
use the \l {Asynchronous Landmark Requests} {request classes} which use the manager as a parameter.
The manager provides notifications whenever landmarks or categories are added, updated or removed.
Each manager is identified by a manager name which typically takes the form of a reverse domain string
such as \c com.nokia.qt.landmarks.engines.sqlite. However every supported platform provides a default
manager which may be instantiated without having to provide a name like so:
\snippet doc/src/snippets/qtlandmarksdocsample/qtlandmarksdocsample.cpp Instantiate default QLandmarkManager
\section1 Retrieval Operations
To retrieve a set of landmarks we provide may provide a QLandmarkFilter, QLandmarkSortOrder and limit and offset as necessary.
The QLandmarkFilter defines the criteria for selecting landmarks; for example, a QLandmarkCategoryFilter may be used
to choose landmarks that belong to a certain category. A QLandmarkSortOrder order defines how the results should
be sorted. (Note that if you wish to sort by distance, you should use a proxmity filter, see QLandmarkProximityFilter).
The limit allows specification of the maximum number of items to
return and the offset defines the index of the first item. The following demonstrates how to search for the first 100
landmarks belonging to a given category, sorted by name.
\snippet doc/src/snippets/qtlandmarksdocsample/qtlandmarksdocsample.cpp Retrieve landmarks by category synchronously
The set of parameters described above are not always necessary as defaults are provided, if we wanted to retrieve
all landmarks, then the appropriate call is:
\snippet doc/src/snippets/qtlandmarksdocsample/qtlandmarksdocsample.cpp Retrieve all landmarks synchronously
\note Landmark retrieval is potentially a long operation, the synchronous API provided by the manager
is subject to blocking. It is generally recommended that the QLandmarkFetchRequest be used because
it behaves asynchronously.
Categories may be retrieved in a similar manner:
\snippet doc/src/snippets/qtlandmarksdocsample/qtlandmarksdocsample.cpp Retrieve categories synchronously simple
\section1 Saving and Deleting
Saving and deleting landmarks and categories are fairly straightforward. To add a new landmark or category
simply instantiate a QLandmark or QLandmarkCategory, set its data fields (e.g., name, coordinate, etc.) and pass
a pointer to the appropriate save operation. For example:
\snippet doc/src/snippets/qtlandmarksdocsample/qtlandmarksdocsample.cpp Add landmark synchronously simple
We pass the landmark by pointer bcause it will be assigned a new QLandmarkId when the function call is done.
Saving a landmark with a valid id already set will update the existing landmark.
Removal of landmark may be done as follows:
\snippet doc/src/snippets/qtlandmarksdocsample/qtlandmarksdocsample.cpp Remove landmark synchronously simple
\section1 Importing and Exporting
Import and export are potentially long operations, to perform these operations asynchronously
see QLandmarkImportRequest and QLandmarkExportRequest. The simplest way to perform an import
is to supply a file name while an export will need both a file name and format.
\snippet doc/src/snippets/qtlandmarksdocsample/qtlandmarksdocsample.cpp ImportExport landmark simple
The formats supported for import and export can be found by calling the
supportedFormats() function with the type of operation to be performed,
either ImportOperation or ExportOperation.
*/
/*!
\enum QLandmarkManager::Error
Defines the possible errors for the landmark manager.
\value NoError No error occurred
\value DoesNotExistError The most recent operation failed due to an item not being found, usually an import file.
\value LandmarkDoesNotExistError The most recent operation failed due to a specified landmark not being found.
\value CategoryDoesNotExistError The most recent operation faied due to a specified category not being found.
\value AlreadyExistsError The most recent operation failed because the specified landmark or category already exists.
\value LockedError The most recent operation failed because the datastore specified is currently locked.
\value PermissionsError The most recent operation failed because the caller does not have permission to perform the operation.
\value OutOfMemoryError The most recent operation failed due to running out of memory.
\value VersionMismatchError The most recent operation failed because the backend of the manager is not of the required version.
\value NotSupportedError The most recent operation failed because the requested operation is not supported by the manager.
\value BadArgumentError The most recent operation failed because one or more of the parameters to the operation were invalid.
\value InvalidManagerError The most recent operation failed because the manager failed to initialize correctly and is invalid.
This could be due using a manager name that is not recognised/available. A landmark request object will return this error if
if is assigned a null manager pointer.
\value ParsingError The most recent operation failed because the imported file could not be parsed.
\value CancelError The most recent operation failed to complete due to user cancelation.
\value UnknownError The most recent operation failed for an unknown reason.
*/
/*!
\enum QLandmarkManager::TransferOption
Defines the possible options when transferring landmarks during import or export.
\value IncludeCategoryData During an import, category data is included. If an imported category doesn't exist
the category is created. If the imported category name matches an existing
category name, then the landmark is added to that category. For exports, categories
are included in the exported file if the file format allows it.
\value ExcludeCategoryData Landmarks are imported or exported without any categories assigned to the landmarks.
\value AttachSingleCategory Only relevant for import operations. When landmarks are imported they are
all assigned to a given category.
*/
/*!
\enum QLandmarkManager::ManagerFeature
Defines the possible features the landmark manager can support.
\value ImportExportFeature The manager supports import and/or export operations
\value NotificationsFeature The manager will emit notification signals when landmarks/categories have
been added/modified/removed from the datastore it manages.
*/
/*!
\enum QLandmarkManager::SupportLevel
Defines the possible support levels the manager can provide for a given filter or sort order list.
\value NativeSupport The manager natively supports the filter or sort order list.
\value EmulatedSupport The manager emulates the behaviour of the filter or sort order list.
Emulated behaviour will inherently be slower than a natively supported implementation.
\value NoSupport The manager does not support the filter or sort order list at all.
*/
/*!
\enum QLandmarkManager::TransferOperation
Defines the type of transfer.
\value ImportOperation Landmarks are being copied from a file to the device.
\value ExportOperation Landmarks are being copied from the device to a file.
