java - SocketInitiator getSession give session not at the same order as in the config file -


when try sessionconfig index exist in file contains sessionconfig (in our case "initiatorsettings.cfg")

[default] filestorepath=data filelogpath=log heartbtint=30 reconnectinterval=5  [session]  sessionname=badisinit1 beginstring=fix.4.2 sendercompid=client1 targetcompid=server1 connectiontype=initiator socketconnectport=9878 socketconnecthost=localhost usedatadictionary=n  [session]  sessionname=init0badis beginstring=fix.4.2 sendercompid=client1 targetcompid=server12 connectiontype=initiator socketconnectport=9878 socketconnecthost=localhost usedatadictionary=n  [session]  sessionname=test211 beginstring=fix.4.2 sendercompid=badis targetcompid=server connectiontype=initiator socketconnectport=9878 socketconnecthost=localhost usedatadictionary=n

i sessions in different orders, in first 2 sessionids:

 session id fix.4.2:client1->server12  session id fix.4.2:client1->server1  session id fix.4.2:badis->server

there code have used load sessions , print them don't know if normal have different orders in file , after load them, or there wrong config file ..

        sessionsettings sessionsettings = new sessionsettings("initiatorsettings.cfg");          applicationimp mainapplication = new applicationimp();          filestorefactory filestorefactory = new filestorefactory(sessionsettings);          filelogfactory logfactory = new filelogfactory(sessionsettings);          messagefactory messagefactory = new defaultmessagefactory();          socketinitiator = new socketinitiator( mainapplication,                 filestorefactory, this.sessionsettings, logfactory,                 messagefactory);          for(int i=0;i<socketinitiator.getsessions().size();i++)         {             system.out.println("get session id "+socketinitiator.getsessions().get(i));         }

thanks help.

it normal behavior sessions not ordered sessionid->sessions stored in hashmap , converted list on getsessions() method.

from sessionconnector (superclass of socketinitiator)

public arraylist<sessionid> getsessions() {     return new arraylist<sessionid>(sessions.keyset()); }

(as reminder, hashmap doesn't guarantee order of put() call. need linkedhashmap that.)

a suggestion aside modifying core code, add property ordered list of sessionids , iterate through property , in getsessionmap()

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
