Im currently trying to retrieve the column header used in a flexible search using java. However i cannot find any method in hybris to do so.
Here is my method to process the flexible search:
private List<List<Object>> processFlexibleQuery(final String flexibleQuery, final List<String> paramValues, final List<String> paramNames, final int headersCount) 
    {
        final Map<String, Object> params = new HashMap<>();
        final FlexibleSearchQuery query = new FlexibleSearchQuery(flexibleQuery);
        final Class[] resultTypesArray = new Class[headersCount];
        for (int i = 0; i < headersCount; i++)
        {
            resultTypesArray[i] = String.class;
        }           
        query.setResultClassList(Arrays.asList(resultTypesArray));
        if (paramValues.size() > 0 && paramNames.size() == paramValues.size())
        {
            for (int i = 0; i < paramValues.size(); i++)
            {
                params.put(paramNames.get(i).trim(), paramValues.get(i).trim());
            }
        }
        query.addQueryParameters(params);
        final SearchResult<List<Object>> result = flexibleSearchService.search(query);
        final List<List<Object>> productList = result.getResult();
       return productList;
    }
My method work fine. I have looked up a couple of class provided by hybris to put the column header of the flexible search in a list but i cannot find any method. Basically if i process this FS in my method:
SELECT {p.code} as potato,
       {p.name} as name
FROM {product as p}
I want to have "potato" and "name" in a list. I dont want to parse directly the query using the "as" because if there is a subquery in the flexible search this will bug out. Any idea?
