    Session: How to Refresh an Entity

    To update an entity with the latest changes from the server, use the refresh method from advanced session operations.

    Syntax

    <T> void refresh(T entity);
    Parameter Type Description
    entity T Instance of an entity that will be refreshed

    Example

    Employee employee = session.load(Employee.class, "employees/1");
Assert.assertEquals("Doe", employee.getLastName());

// LastName changed to 'Shmoe'

session.advanced().refresh(employee);

Assert.assertEquals("Shmoe", employee.getLastName());

    Remarks

    Refreshing a transient entity (not attached) or an entity that was deleted on server-side will result in a IllegalStateException.
