Couchbase java N1QL DSL query statement with IN expression

Trying to write a N1QL query like

    SELECT * from bucket
    WHERE s IN ["s1", "s2", ..., "sn"]
    END;

in DSL. Assuming I have a list of Strings called s_array, I need to write something like this:

select("*").from("bucket")
.where(x("s").in(s_array);

Whats the best way to write the IN expression in DSL without concatenating all list elements in a String or something?
