Extract values from custom function for ValueSource with multiple indexable fields

[Costi Muraru]

Hi guys,

I have a custom FieldType that adds several IndexableFields for each
document.
I also have a custom function, in which I want to retrieve these indexable
fields. I can't seem to be able to do so. I have added some code snippets
below.
Any help is gladly appreciated.

Thanks,
Costi

public class MyField extends FieldType {
    @Override
    public final java.util.List<IndexableField> createFields(SchemaField
field, Object val, float boost) {
        List<IndexableField> result = new ArrayList<IndexableField>();
        result.add(new Field(field.getName(), "field1", FIELD_TYPE));
        result.add(new Field(field.getName(), "123", FIELD_TYPE));
        result.add(new Field(field.getName(), "ABC", FIELD_TYPE));
        return result;
    }
}


public class MyFunctionParser extends ValueSourceParser {
    @Override
    public ValueSource parse(FunctionQParser fqp) throws SyntaxError {
        ValueSource fieldName = fqp.parseValueSource();
        return new MyFunction(fieldName);
    }
}

public class MyFunction extends ValueSource {
    ...
    @Override
    public FunctionValues getValues(Map context, AtomicReaderContext
readerContext) throws IOException {
        final FunctionValues values = valueSource.getValues(context,
readerContext);
        LOG.debug("Value is: " + values.strVal(doc); *// prints "123" - how
can I retrieve the "field1" and "ABC" indexable fields as well?*
    }
}
