7:00 – 5:30 VTX

• Finished Social Media and Trust during the Gezi Protests in Turkey.
• More Hibernate
  • After stepping through the ‘Showroom’ example on pg 54 (Using a Join Table), of Just Hibernate I think I see my problem. In my case, the corpus has already been created and exists as an entry in the corpora table. I need to add a relationship when a word is run against a new corpus. Which come to think about it, should have the word count in it. Maybe?
  • Ok, I don’t like the way that ManyToMany is implemented. Hibernate should be smart enough to figure out how to make a default mapping table. Sigh.
  • And you have to call each object with the other object or it doesn’t load properly.
  • After being annoyed for a while, I decided to try reflection as a making fewer calls. The following still needs the get/set member element calls, but I like the direction it’s going. Will work on it some more tomorrow (need to add the call on the this class):

    public void addM2M(Object obj){
        System.out.println("person.addM2M");
        Class thisClass = this.getClass();
        String thisName = thisClass.getName();
        Class thatClass = obj.getClass();
        Method[] thatMethods = thatClass.getMethods();
        Method thatMethod = null;
        for(int i = 0; i < thatMethods.length; ++i){
            Method m = thatMethods[i];
            Type[] types = m.getGenericParameterTypes();
            if (types.length == 1) { // looking for one arg setters
                for (int j = 0; j < types.length; ++j) {
                    Type t = types[j];
                    if ((t.getTypeName() == thisName)) {
                        thatMethod = m;
                        break;
                    }
                }
            }
            if(thatMethod != null){
                break;
            }
        }
        if(thatMethod != null){
            try {
                thatMethod.setAccessible(true);
                thatMethod.invoke(obj, this);
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                System.out.println("addM2M failed: "+e.getCause().getMessage());
                e.printStackTrace();
            }
        }
    }
