Loading and saving

In order to keep loading and saving mechanisms reliable, the following rules apply:

• Only the following functions are allowed to call the read, write and adoptDocument methods of the *DocStorage classes or to create an instance of such a class.
  • EquationEnv.prototype.save
  • GemsePEditor.prototype.newDocStorageByURI
  • GemsePEditor.prototype.freeUnusedDocStorage
  • GemsePEditor.prototype.loadURI
  • GemsePEditor.prototype.loadFromOpenDocument
• The other methods defined in the DocStoragePrototype can be called from everywhere. Additional methods or variables of an instance of a *DocStorage must not be touched.
• All open documents are tracked in the storages array of the GemsePEditor instance.
• Closing an equation must be done by calling the method eliminateEquationEnv of the GemsePEditor instance, or close of the EquationEnv instance (which in turn calls eliminateEquationEnv).

The *DocStorage classes are defined in storage.js.
