It allows you to maintain additional support services as well by implementing simple interfaces. Hibernate works with various support services such as connection pools, caching services, and transaction managers. Hibernate can be configured to adapt to different environments, whose requirements vary. Persistent class configuration allows you to bridge gaps between the class and databases.Īlthough it’s commonly used within J2EE (Java EE) application servers such as WebSphere and JBoss, Hibernate can also be used in standalone applications. Provide Hibernate with information about the classes to be persisted. ![]() This includes database connection parameters, caching, and the collection of persistent classes managed by Hibernate. Hibernate is typically configured in two steps. For instance, the differences in obtaining database connections can be significant. After all, running a standalone application can be quite different from running a Web application. Supporting these variations requires Hibernate to be highly configurable.

However, as long as you are not returning a value by using kotlin when, you will not be required to have a default content and product recommendations are editorially independent. ![]() In other words, should you use the kotlin when function to return a value, you will be forced to include an else block in the function or the compiler will flag an error. A default case is optional as long as when is not being used to return a value. Like switch and if-else, kotlin when allows you to specify a default case that will execute when none of the specified conditions have been found. Finally, when is also useful for exception handling. The second involves returning a value based on a try condition. The first case is comparing a value and then executing the proper branch of code when a true condition has been found. There are three primary different uses where using kotlin when is practical. It is critical that you understand when to use the kotlin when function because when used properly, when can greatly increase the readability of your code. The kotlin when extension function is part of the Kotlin standard library and it is used to replace both the switch statement as well as the if-else statements.
