class QgsProjectStorage
{
%Docstring
Abstract interface for project storage - to be implemented by various backends
and registered in QgsProjectStorageRegistry.

.. versionadded:: 3.2
%End

%TypeHeaderCode
#include "qgsprojectstorage.h"
%End
  public:

    class Metadata
{
%Docstring
Metadata associated with a project

.. versionadded:: 3.2
%End

%TypeHeaderCode
#include "qgsprojectstorage.h"
%End
      public:
        QString name;
        QDateTime lastModified;
    };

    virtual ~QgsProjectStorage();

    virtual QString type() = 0;
%Docstring
Unique identifier of the project storage type. If type() returns "memory", all project file names
starting with "memory:" will have read/write redirected through that storage implementation.
%End

    virtual QStringList listProjects( const QString &uri ) = 0;
%Docstring
Returns list of all projects for given URI (specific to each storage backend)
%End

    virtual bool readProject( const QString &uri, QIODevice *device, QgsReadWriteContext &context ) = 0;
%Docstring
Reads project file content stored in the backend at the specified URI to the given device
(could be e.g. a temporary file or a memory buffer). The device is expected to be empty
when passed to readProject() so that the method can write all data to it and then rewind
it using seek(0) to make it ready for reading in :py:class:`QgsProject`.
%End

    virtual bool writeProject( const QString &uri, QIODevice *device, QgsReadWriteContext &context ) = 0;
%Docstring
Writes project file content stored in given device (could be e.g. a temporary file or a memory buffer)
using the backend to the specified URI. The device is expected to contain all project file data
and having position at the start of the content when passed to writeProject() so that the method
can read all data from it until it reaches its end.
%End

    virtual bool removeProject( const QString &uri ) = 0;
%Docstring
Removes an existing project at the given URI. Returns true if the removal
was successful.
%End

    virtual bool renameProject( const QString &uri, const QString &uriNew );
%Docstring
Rename an existing project at the given URI to a different URI. Returns true if renaming
was successful.
%End

    virtual bool readProjectStorageMetadata( const QString &uri, QgsProjectStorage::Metadata &metadata /Out/ );
%Docstring
Reads project metadata (e.g. last modified time) if this is supported by the storage implementation.
Returns true if the metadata were read with success.
%End

    virtual QString visibleName();
%Docstring
Returns human-readable name of the storage. Used as the menu item text in QGIS. Empty name
indicates that the storage does not implement GUI support (showLoadGui() and showSaveGui()).
The name may be translatable and ideally unique as well.
%End

    virtual QString showLoadGui();
%Docstring
Opens GUI to allow user to select a project to be loaded (GUI specific to this storage type).
Returns project URI if user has picked a project or empty string if the GUI was canceled.
%End

    virtual QString showSaveGui();
%Docstring
Opens GUI to allow user to select where a project should be saved (GUI specific to this storage type).
Returns project URI if user has picked a destination or empty string if the GUI was canceled.
%End
};
