How to correctly use clear(), evict() and close() methods in Hibernate?

I have read more information about these commands but didn't understand exactly what a right way to use these commands?.

I want to discover deeply the difference between clear(), evict() and close() methods in details. As I know evict() will clear particular object from session in hibernate and clear() will clear all objects from session.

How to use them correctly? Thanks

Approximately the definition of the commands:

Clear (): When this method get called inside transaction boundry then all objects which are currently associate with particular session will be disconnected / clean or no longer associate with that Session instance. Therefore, after calling this method nothing will be performed on persistance layer or DB.

Evict(): Removes the object from the session. This method is used to dissociate/disconnect the specified object from the session.

Close() : Close session by calling session.close() method, means End the session and releasing the JDBC Connection and clean up.

Examples of using these commands you can find here.
