The CommonTreeNodeStream constructor fails to pass 'adaptor' into the
TreeIterator:
public CommonTreeNodeStream(TreeAdaptor adaptor, Object tree) {
super(adaptor.create(Token.EOF, "EOF")); // set EOF
this.root = tree;
this.adaptor = adaptor;
it = new TreeIterator(root);
it.eof = this.eof; // make sure tree iterator returns the EOF we want
}
This results in the following constructor being called:
public TreeIterator(Object tree) {
this(new CommonTreeAdaptor(),tree);
}
Which results in the UP, DOWN, and EOF tokens not being of the correct
class as created by the other TreeIterator constructor:
public TreeIterator(TreeAdaptor adaptor, Object tree) {
this.adaptor = adaptor;
this.tree = tree;
this.root = tree;
nodes = new FastQueue();
down = adaptor.create(Token.DOWN, "DOWN");
up = adaptor.create(Token.UP, "UP");
eof = adaptor.create(Token.EOF, "EOF");
}
Thanks.
