custom yml get enum

Does anyone know how to get the value of an enum object from a custom yml file?

Code:

public static QuestTyp getQuestQuestTyp(String questname) {
        String questTyp = FileHandler.quests.getString(questname+".QuestTyp");
        QuestTyp quest = QuestTyp.valueOf(questTyp);
        return quest;
    }

I want to get the typ of the quest with the methode.
The methode should return the value of an enum object (QuestTyp).
How can I read a simple input in the yml file.
Thats my yml file:

Code:

quest1:
  Name: 'Killer'
  Description: 'We was conquered by Creepers. Kill them!'
  QuestTyp: 'kill' //Thats an enum value.
  ObjectTyp: 'Creeper' // Thats an enum value too
  reqAmount: 10
  MoneyReward: 40
quest2:

Does anyone know a good way to "read" and return it??
My code doesnt work. There is a Nullpointer error.
Hope you understand my problem.
Thanks.

 

Unfortunately YamlConfiguration doesn't have built in support for Enum values. You can use something like this;

Code:JAVA

public Enum getEnum(Class clazz, String string) throws Exception {
    if(!clazz.isEnum()) throw new Exception("Class "+clazz.getName()+" is not an enum.");
    for(Object constant : clazz.getEnumConstants()) {
        if(((Enum) constant).toString().equals(string)) {
            return (Enum) constant;
        }
    }
    throw new Exception("String "+string+" not a valid enum constant for "+clazz.getName());
}

That's the method I use in my SuperEasyConfig. To use it with your example it would be;

Code:JAVA

public static QuestTyp getQuestQuestTyp(String questname) {
    String questTyp = FileHandler.quests.getString(questname+".QuestTyp");
    QuestTyp quest = null;
    try {
        quest = getEnum(QuestTyp.class, questTyp);
    } catch(Exception ex) {
        ex.printStackTrace();
        return null;
    }
        return quest;
}

 

Thank you very much. I'll test it.

Im very worry about it but it doesnt work.
There is still a Nullpointer error. I casted
quest = getEnum(QuestTyp.class, questTyp);
to
quest = (QuestTyp) getEnum(QuestTyp.class, questTyp);
Please help me!

Sorry, forgot about the reflection trickiness I used around this. Try;

Code:JAVA

public static QuestTyp getQuestQuestTyp(String questname) {
    String questTyp = FileHandler.quests.getString(questname+".QuestTyp");
    QuestTyp quest = null;
    try {
        quest = QuestTyp.values()[getEnum(QuestTyp.class, questTyp).ordinal()];
    } catch(Exception ex) {
        ex.printStackTrace();
        return null;
    }
    return quest;
}

 

Sorry. It worked with my original code. I used a wrong variable to call the methode. I used not the username but a not inialized variable. Very nooby mistake. xDDD
But thanks for your source code examples.
