c# - designing virtual methods -

-

I wonder which situation you will choose first or second design:

The first design: The child method has to call the base method 

  public abstract class base {public virtual zero enabled () {IsEnable = true; } Disable Public Virtual Zero () {IsEnable = false; } Public Child Elastic (Receive; Private Set;}} Public Square Child: Base {Enabling Public Override Zero () (*) * * * / base.Enable ();} Disable the public override zero () {/ * Do not forget to call the base  / P> 
  Public intangible class base {Enable Public Zero () {IsEnable = true; OnEnable ();} Disable Public Zero () {IsEnable = false; OnDisable ();} Public Child Eligible (Receive; Private Set;} Public Virtual Zero OnEnable () {} Public Virtual Zero On-Disk Basic () {}} Public Class Child: Base {Override Zero Onable () / / Work * Overwrite Zero On Disabling () * / * Work * /}}  
 
 Thanks

 It depends if you really want to make sure  isEnable  gets set Whether or not you can visualize scenarios in which the user does not want to set it, I think that you leave them to call the base method. Otherwise, do this for them.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
