In other words, of all the join operations, outer join operations like
LEFT_JOIN are disallowed.
Besides performing self-join on a base table, this table lens might
cooperate with JoinTableLens or CrossJoinTableLens to
perform non-equal join operations on two base table lenses; in this case,
the JoinTableLens or CrossJoinTableLens should be the
base table lens of this table lens.
