Aleksandar Babic commented on JENA-1295:
----------------------------------------
It looks much better, but there is an error, addValues for ?x should be
{code}.addValues("?x", "foo", "fu"){code}
However, there should be a method overloading (or type checking) for those who
want to send a large list of values for single variable:
{code}
.addValues("?x", Arrays.asList("foo", "fu"))
{code}
as well as to add all at once:
{code}
Map<String, List<String>> values = new HashMap<>(2);
values.put("?x", Arrays.asList("foo", "fu"))
values.put("?y", Arrays.asList("bar", "baz"))
builder.addValues(values);
{code}
I forgot size of all collections should be the same, but it makes sense to
perform check. Additional, "Values builder" might be good fit here as well:
{code}
Values values = new Values.Builder("?x", "?y")
.withData(Arrays.asList("foo", "fu"))
.withData(Arrays.asList("bar", "baz"))
.build();
selectBuilder.setValues(values);
{code}
P.S. Note that values support
"[UNDEF|http://www.snee.com/bobdc.blog/2012/09/sparql-11s-new-values-keyword.html]";
as keyword, which should be also supported.
