Hi. good question. it's a view of list w/o making a copy for
efficiency.
that said, i think i've removed it; unnecessary. my dev branch shows
these ctors:
public CommonTreeNodeStream(Object tree) {
this(new CommonTreeAdaptor(), tree);
}
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
}
