Szu-Yu Wang commented on CXF-4221:
----------------------------------
and the code to use the attached FiqlParser:
{noformat}
public List<Merchant> getMerchants(SearchContext searchContext) throws
DataNotFoundException {
try {
String searchExpression =
searchContext.getSearchExpression();
CriteriaBuilder builder = em.getCriteriaBuilder();
CriteriaQuery<Merchant> cq =
builder.createQuery(Merchant.class);
Root<Merchant> root = cq.from(Merchant.class);
Predicate pred = new FiqlParser<Merchant>(
Merchant.class).parse(searchExpression,
root, builder );
cq.where(pred);
TypedQuery<Merchant> q = em.createQuery(cq);
List<Merchant> results = q.getResultList();
return results;
} catch (FiqlParseException fpe) {
throw new
DataNotFoundException(DataExceptionEnum.DATA_NOT_FOUND);
}
}
{noformat}
> FIQL visitor to return a generic <K> instead of String

> It would be great if SearchConditionVisitor<T, K> where K was the return type
> of the getResult() call. This way, I can CriteriaQuery<T> instead of String.
> Also, incidentally, the operation isn't "getResult", it's more like
> "getPredicate" or "getFilter"...
