Indexing of a non database property variable in a class

OK so I have a variable in my class that contains several other variables that have an @Field and that are mapped to a database field value. I also have another variable that I want to set either true or false depending on what value a database field contains.

What I am trying to do is to make this un-mapped variable (doesn't correspond to a database field) to be indexed and saved along with the other indices. Is this possible?

Here is how I'm declaring my variable:

Code:

// un-mapped variable NOT INDEXED:
@Field(index = Index.UN_TOKENIZED, store = Store.YES)
@Transient
protected boolean ageSetField;

...

// mapped variable INDEXED:
@Field(index = Index.UN_TOKENIZED, store = Store.YES)
@Column(name = "age")
protected int age;

But it's not being added to the index. The way its getting set is in this method:

Code:

public void setAge(int age) {
        if (age  <= 0) {
            this.age = null;
            this.ageSetField = false;
        } else {
            this.age = age;
            this.ageSetField = true;
        }
    }

Any thoughts? I also tried making a setAgeSetField() that I would call from setAge() but it still didn't work.

Thank you!

could you try it on a getter method?
I know it worked as I've used the same strategy in the past, but I never annotate fields.

Hi thanks for the reply. I have both a getter and setter methods. I know the index is not being created because I am using Luke to check the indices. And the 'ageSetField' is the only one that is missing.

I am using annotations and not the xml...

Any thought are greatly appreciated!

Ok then try moving the annotations from the fields to the getters

Hi sorry for delayed reply, I have been out of town. OK I'm still trying to figure this out. I put the annotation by the method like you suggest but it still wont index. Here is what the replaced annotations now look like:

Code:

@Transient
protected boolean ageSetField;

...

@Field(index = Index.UN_TOKENIZED, store = Store.YES)
public Boolean getAgeSetField(int age) {
       return ageSetField;
}

public void setAgeSetField(Boolean ageSetField) {
       this.ageSetField = ageSetField;
}

If I move the @Transient from the field to the getter method I get exception thrown out.

you didn't post the exception, but a polite guess makes me thing that you have all annotations on fields. you can't jsut move one, you have to move all annotations to getters as one rule must be chosen consistently.

OK so I figured out the problem...the problem is in the method:

Code:

@Field(index = Index.UN_TOKENIZED, store = Store.YES)
public Boolean getAgeSetField(int age) {
       return ageSetField;
}

It's not returning anything and so I'm guessing that's why its not being created. Its not being set even though I havethis:

Code:

public void setAge(int age) {
        if (age  <= 0) {
            this.age = null;
            this.ageSetField = false;
        } else {
            this.age = age;
            this.ageSetField = true;
        }
    }

So what I had to do was to give the ageSetField a value directly in the method like so:

Code:

@Field(index = Index.UN_TOKENIZED, store = Store.YES)
public Boolean getAgeSetField(int age) {

       if (age  <= 0) {
           return false;
        } else {
            return true;
        }

}

And after I do that THEN the index is created for ageSetField. Any idea why that is? why isn't it set in the initials setAge() method??

Thanks!

that's your code :) Are you sure you're calling setAge() ?

This is where I'm ignorant with the workings of the indexing and such. The age IS set and saved and indexed for Age (which is a DB mapped field). That's where I was hoping you could shed some light. As far as I know a getter and setter method is required for each DB mapped class variable/property that has the @Field and @Column annotation. So again, age is a property in my class with its own @Field and @Column and it is mapped to a DB field in table. Age property is set correctly and indexed. However when I try to also set the non DB mapped variable that only has @Field but no @Column (ageSetField) then that is not set at all even though I'm setting it in the setter method for 'age' property which gets set just right!

So what I'm saying is that when I index with the .index() method I was under the impression that setter methods are called somewhere automatically....
