== Description ==

Returns the strings provided to constructor. The returned rows have one column with the default role.

== Constructor ==

Literals(String s1,...)

== Notes ==

The from method present in every directive can be given strings instead of directives. In this case a Literals directive is implicitly from the strings. A.from("b","c","d") resolves to new From(A,new Literals("b","c","d")).
