java - Is this a DAO manager pattern? What are the appropriate class and interface names? -


i have interface, somethingdao, , implementing class, somethingdaoimpl. interface consists of 11 methods, each method requires 1 or more complex sql queries.

i broke implementing class several smaller classes, let's call them helper1, helper2, helper3, ... helpern lack of better names. somethingdaoimpl has instance of each, , routes method calls each.

public class somethingdaoimpl implements somethingdao {     private helper1 helper1;     private helper2 helper2;     private helper3 helper3;     // ...     private helper8 helper8;      public list<x> getx(...) {         return helper1.getx();     }      public list<y> gety(...) {         return helper2.gety();     }       public list<x> getdetailedx(...) {         list<x> ds = getx(...);           helper6.addto(ds);         helper7.addto(ds);         helper8.addto(ds);          return ds;     } }

is there name technique? complex dao has several "worker" bees work it, , manages them?

is dao manager pattern, helper1, helper2, helper3 dao objects? i'm interested in proper naming conventions, in case rename somethingdaoimpl somethingdaomanager, , helper become helperdao.

i have seen name 'service' used in place, in case somethingdao interface renamed somethingservice, , worker-bee classes carry dao @ end of names.

thanks... think looking naming conventions, , design pattern, associated scenario. implementation clear possible, , having names suggest pattern using helpful.

imo code 'bad code' pattern, more tight coupled code. 8 helpers lot , it's clealry badly designed object. know java , don't have c# extension methods ideally helpers, think way use dependency injection via di container.

every object needing dao or service abstract dependencies, constructor arguments. 

public class myobject {     public myobject(isomeservice serv,irepository repo){} }

the point is, use objects relevant context , code take dependencies. highly doubt might need 8 helpers anything. if that's case, code way , needs redesigned.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
