[antlr-interest] A simple Type related question.

[Bharath Sundararaman]

Hi all,

If you had the following statement in your code: "int a := 100000000;" and
you wanted to prompt an error, how can it be done? I use the
integer.parseInt() method to check the range but I have a LONG INTEGER which
can go upto 2^64, which means I cant use Integer.parseInt() to check its
range. Also, how do I check real values? I have a REAL and a LONG REAL and
I'm not sure how to check if the values assigned to them will be acceptable.

Thanks,

Bharath.

Any particular reason the ones that currently exist don't fit your needs?
You might be better off enhancing an existing one, rather than starting from
scratch.

You'll probably want to have two Parsers here, one for the Java code and one
for the Javadoc comments.

I seem to remember this is in the tree construction documentation for antlr,
but could be mistaken.

One can be found on the antlr website, although it tosses comments, which is
why I suggested two parsers in 1.
