Question
What does the following code snippet do? Why the use of Evict
?
private void DoEvict(customer cust)
{
AddressRepository.Evict(cust.Address);
cust.Address = AddressRepository.Get(cust.Address.Id);
}
Solution
The evict removes that specific "Address" reference from the NHibernate first level cache.
If the first instruction in your code snippet was not executed, the second one, instead of fetching the item from the DB, would simply return it from the first level cache.
OTHER TIPS
Session.evict() is used to remove a particular object from Persistent state to Detached state.
