Description

Create subclasses for all the driver classes that have async methods and handle both callback and promise returning support

AC

• Create wrappers that handle overload logic (options are optional usually)
• If callback is provided use callbackify if possible to wrap the driver's API
  • When we are returning an instance of our own class ensure you capture the result and return and instance of the LegacyX version of it.
• Add helper [Symbol.for('@@mdb.callback.toLegacy')] method to the prototype of each legacy class
• overload the constructor to handle creating a new legacy instance from a baseClass instance

Test AC

• Cover methods that convert to a legacy type with unit tests that prove we always convert to the legacy version of a class
