Login asynchronous UML

Sequence diagram for logIn using a delegate for asynchronous callbacks.

User can log in by calling login() submitting parameters with the credentials of:

• username
• password
• tenant

Create a Delegate that will get an input-callback of either:

• success
• error

Call the logIn() with credentials and the pointer to the delegate that is going to handle the callback.

Normally you need to wait for the completion and then, depending on if the result was success or error, take an appropriate action.
