mxAutoSaveManager

Manager for automatically saving diagrams.  The save hook must be implemented.

Example

var mgr = new mxAutoSaveManager(editor.graph);
mgr.save = function()
{
  mxLog.show();
  mxLog.debug('save');
};

Functions

mxAutoSaveManager

function mxAutoSaveManager(graph)

Constructs a new automatic layout for the given graph.

Arguments

graphReference to the enclosing graph.

Variables

graph

mxAutoSaveManager.prototype.graph

Reference to the enclosing mxGraph.

autoSaveDelay

mxAutoSaveManager.prototype.autoSaveDelay

Minimum amount of seconds between two consecutive autosaves.  Eg. a value of 1 (s) means the graph is not stored more than once per second.  Default is 10.

autoSaveThrottle

mxAutoSaveManager.prototype.autoSaveThrottle

Minimum amount of seconds between two consecutive autosaves triggered by more than <autoSaveThreshhold> changes within a timespan of less than autoSaveDelay seconds.  Eg. a value of 1 (s) means the graph is not stored more than once per second even if there are more than autoSaveThreshold changes within that timespan.  Default is 2.

autoSaveThreshold

mxAutoSaveManager.prototype.autoSaveThreshold

Minimum amount of ignored changes before an autosave.  Eg. a value of 2 means after 2 change of the graph model the autosave will trigger if the condition below is true.  Default is 5.

ignoredChanges

mxAutoSaveManager.prototype.ignoredChanges

Counter for ignored changes in autosave.

lastSnapshot

mxAutoSaveManager.prototype.lastSnapshot

Used for autosaving.  See <autosave>.

enabled

mxAutoSaveManager.prototype.enabled

Specifies if event handling is enabled.  Default is true.

changeHandler

mxAutoSaveManager.prototype.changeHandler

Holds the function that handles graph model changes.

Functions

isEnabled

mxAutoSaveManager.prototype.isEnabled = function()

Returns true if events are handled.  This implementation returns enabled.

setEnabled

mxAutoSaveManager.prototype.setEnabled = function(value)

Enables or disables event handling.  This implementation updates enabled.

Parameters

enabledBoolean that specifies the new enabled state.

setGraph

mxAutoSaveManager.prototype.setGraph = function(graph)

Sets the graph that the layouts operate on.

save

mxAutoSaveManager.prototype.save = function()

Empty hook that is called if the graph should be saved.

graphModelChanged

mxAutoSaveManager.prototype.graphModelChanged = function(changes)

Invoked when the graph model has changed.

reset

mxAutoSaveManager.prototype.reset = function()

Resets all counters.

destroy

mxAutoSaveManager.prototype.destroy = function()

Removes all handlers from the graph and deletes the reference to it.
