To add the new type WORD, I think you need to do the following:
(1) Add a new type WORD in BaseType.java. (2) In TypeLattice.java, add the new type WORD to the lattice, remove the edge from INT to DOUBLE, and add the edges from INT to WORD, and from WORD to DOUBLE. (3) Modify DoubleToken.convert() so that this method can convert an instance of WordToken to DoubleToken. And in WordToken.conert(), convert an instance of IntToken to WordToken. I realize that it is not ideal that you have to modify the source code to add a new type. But I'm not sure how much automation can be done with respect to type conversion. If you have any problem, please let me know. -Yuhong On Mon, 22 Apr 2002, Bill Wood wrote: > I want to define a new Token type, Word, that has no more precision than > Double; > for inheritance purposes I can subclass DoubleToken.
