The web application obtains an access token instead of using Facebook user credentials to access protected resources. Facebook uses the OAuth 2.0 protocol framework, which enables web applications (called 'clients') that are not normally Facebook resource owners but represent Facebook users to request access to resources controlled by Facebook users and hosted by Facebook servers. This is an example of a UML sequence diagram, which shows how to authenticate Facebook users in a web application to allow access to their Facebook resources. This creates a Hibernate session behind the background interceptor and starts a Hibernate JDBC transaction, so the business method will run in the context of the new transaction.Įxample2: Facebook User Authentication Sequence Diagram of flip flops can be calculated as N 2n-1. When you create a scenario on an element and then generate a Sequence diagram, an Interaction is created as a child of the selected element to act as a container for the diagrams - the Basic, Alternate and Exception paths are each modeled as a separate Sequence diagram under the Interaction. First, count the number of zeros and ones in the given sequence. When a certain business method is called, Spring Transaction Interceptor may intercept it. The number of flip flops can be decided through the given sequence like the following. The Spring application development framework for enterprise Java integrates Hibernate transaction management. svg visualizes of the diagram files Run the following from the root folder that has all of your diagram files. (Optionally) Use the diagram CLI to automatically generate. Here, we provide an example of a UML sequence diagram that illustrates transaction management related to exception handling.
