Hi devs,
Right now the QueryFilter interface allows to modify the query statement and to filter
returned results but doesn't allow to pass dynamic value.
I'm currently implementing a filter that'll return only results for the current
language and thus I need this dynamicity.
Are you ok that I break the QueryFitler API to add a new method:
public interface QueryFilter
{
String filterStatement(String statement, String language);
List filterResults(List results);
// New method
Map<String, String> getParameters();
}
WDYT?
Thanks

Noe that the only other option I know of is to have a ParametrizedQueryFilter IF and do an
instanceof in HqlQueryExecutor.
It's less clean but would not break the API.

Actually I don't need this for my use case even though there could be other use cases
for this later on ;)
Thanks

This second proposal was to avoid breaking an API (I personally prefer the first
proposal). You need an IF in order to cast to ParametrizedQueryFilter and call the
getParameters()/bindParameters() method.
Note that in the end I didn't need anything since I was able to work around the issue
in my case:
// Note that we cannot have SQL injection here since getCurrentLanguage() will
always return a valid Locale
return insertWhereClause(String.format("(doc.language is null or doc.language
= '' or doc.language = '%s')",
getCurrentLanguage().toString()), statement, language);
So this need is less urgent. We can push it till we get the need again…
