java - Hibernate 3.6 customize the setter of one to many mapping -


i have simple @onetomany mapping:

public class member(){     ....     @onetomany(fetch = fetchtype.lazy, mappedby="member", orphanremoval=true)     private list<user> users;      @transient     private user firstuser;     ...      public setusers(list<user> users){       //if(users.size() > 0) this.firstuser = users.get(0);       this.users = users;     }  }  public class user(){     .....     @manytoone     @joincolumn(name = "user_id")     private member member; }

here i'd set this.firstuser = users.get(0) if mapped users length greater 0. doesn't work if put code directly setter method commented line in member, example, read member object users size 5, tried print firstuser, firstuser still null, expected result should users.get(0).

any idea?

you try following:

public class member(){     ....     @onetomany(fetch = fetchtype.eager, mappedby="member", orphanremoval=true)     private list<user> users;      @transient     private user firstuser;     ...      public setuser(list<user> users){       if(users.size() > 0) this.firstuser = users.get(0);       this.users = users;     }      @postload     public void settransientuser() {         this.setusers(this.users);     }  }

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.
