Description tronicek 2009-01-25 21:54:33 UTC 
When I create an ExpressionTree for 1 & (2 & (3 & 4)), i.e. (make is of type TreeMaker)

            BinaryTree b = make.Binary(Kind.AND,
                    make.Literal(Integer.valueOf(1)),
                    make.Binary(Kind.AND,
                        make.Literal(Integer.valueOf(2)),
                            make.Binary(Kind.AND,
                                make.Literal(Integer.valueOf(3)),
                                make.Literal(Integer.valueOf(4)))));

and insert it into the source code, it is inserted WITHOUT parentheses, i.e. 1 & 2 & 3 & 4 is inserted.

Currently, the clients of TreeMaker are expected to create tree structure matching exactly the tree that would be
created by the parser for the desired output, including required make.Parenthesis. I agree that the behavior is not very
intuitive in the above case. It might be possible to improve the situation - this should be investigated. Does not
qualify as a defect IMO.

Overtake.
