Implementing custom storage

To implement a custom backend, you need to create your own implementation of the mindplot.PersistenceManager class.

Here is an example skeleton::

function createStorageManager(mindplot) { mindplot.RestStorageManager = new Class({ Extends:mindplot.PersistenceManager, initialize: function(url) { this.parent(); this.backendUrl = url; },

    saveMapXml : function(mapId, mapXml, pref, saveHistory, events) {
        var url = this.backendUrl  + mapId;
        var xmlRequest = new Request({
            url: url,
            method: 'post',
            async: false,
            onSuccess: function(responseText) {
                events.onSuccess();        
            }, 
            onError: function (text, error) {
                console.log("Error saving mindmap to: " + url, text, error);
                events.onError();
            }
        });
        xmlRequest.send();
    },

    loadMapDom : function(mapId) {
            var xmlRequest = new Request({
                url: this.backendUrl  + mapId,
                method: 'get',
                async: false,
                onSuccess: function(responseText) {
                    xml = responseText;
                }
            });
            xmlRequest.send();

            // If I could not load it from a file, hard code one.
            if (xml == null) {
                throw "Map could not be loaded";
            }
            var parser = new DOMParser();
            return parser.parseFromString(xml,  "text/xml");
       }

}
);
return new mindplot.RestStorageManager(url);

}

In your script for loading the mindmap you add a call to the callback into the loadcomplete method::

 $(document).addEvent('loadcomplete', function(resource) {
           //Asset.javascript("{{ asset('bundles/fpgadmin/js/FpgMindmapPersistence.js')}}");
           // Options has been defined in by a external ile ?
           var options = {
                'persistenceManager' : createStorageManager(mindplot, "http://localhost/my/rest/interface");    
                viewPort: {
                    height: parseInt(window.innerHeight - 70), // Footer and Header
                    width:  parseInt(window.innerWidth)
                },
                size : {
                height: parseInt(screen.height),
                width:  parseInt(screen.width)
            },
            "readOnly":false,
            "zoom":1.3,
            "container":"mindplot"
            "mapId" : "myMapId"
           };
           var designer = buildDesigner(options);
           var persistence = mindplot.PersistenceManager.getInstance();
           var mindmap;
           try {
               mindmap = persistence.load(mapId);
           } catch(e) {
               // If the map could not be loaded, create a new empty map...
               mindmap = mindplot.model.Mindmap.buildEmpty(mapId);
           }
           designer.loadMap(mindmap);
       });
