vb.net - Setting shared values in a for/next loop -


i have shared array needs calculation each index. right now, array initialized in new() , executes each time object created, redundant. how can set array initialized once, when created? static block in java?

i didn't include code because thought simple question. constructor called 64 times (working values of bits) , relevant code :

' decimal value of each bit public shared bitvalue(63) long  public sub new()     ' other non-relevant code here.      index = 0 63         bitvalue(index) = 1l << index     next end sub

just in case wondering heck i'm doing, i'm rewriting java program did works casting , bitwise operators. part of learning vb, i'm working on translation. can idea of headed going http://sourceforge.net/projects/javabitwise/.

you can initialize right away

class test1      private shared _list new list(of string) {"1", "2"}  end class

or in shared constructor

class test2      private shared _list list(of string)      shared sub new()         _list = new list(of string)         _list.add("1")         _list.add("2")     end sub  end class

or check if value initialized or not in new

class test3      private shared _list list(of string)      public sub new()          ' use synclock         if _list nothing             _list = new list(of string)             _list.add("1")             _list.add("2")         end if      end sub  end class

or put list in singleton

sequelize.js - Sequelize: sort by enum cases -

i have model ( article ) field (the name type ) of type enum('source', 'translated') , return 1 article ordered type field. source articles should returned before translated articles. like: article.findone(order: [ { type: [ 'source', 'translated' ] } ]); unfortunately there appears no built-in solution sorting enums. instead have sort by case , couldn't find documentation on how sequelize. what conventional approach here? sorting case hard in sequelize, sort field (the second answer in linked post) should possible: order: sequelize.fn('field', sequelize.col('type'), 'source', 'translated') it's supported mysql far know though
