Function called before any insert, update and remove . Should be set manually since its only stored on the prototype and or your instance.

var db = new Mase('name', [1,2,3]);

db.changed = function(method, newDoc, oldDoc){
  switch(method){
    case 'insert':
      // call your websockets, etc.
    break;
    // etc
    default:
      return ;
    break;
  }
}

The oldDoc and newDoc are passed just before the change is done so beware to not mutate them. If you pass them to another function on the same process I would highly-super-obnoxiously tell you to clone them. If you are using this as is plotted above (for websocket action, etc.) it would be fine.

function changed(string method, object newDoc, object oldDoc)

arguments

• method type string, method that maked the change
• newDoc type object, change performed on document
• oldDoc type object, document to be changed
