gold parser & java

How do you link a function call in a script with a java function ?

For example, if you have the "l = GetLength(str)" scipt line. How do
you link it with the "Integer GetLength(String str)" java function ?

Thanks for your help

You have to write yourself an interpreter. A Parser is just the front end.  Use the parser to build an Abstract Syntax tree.  Each of the nodes in the syntax tree needs to have an Execute or Evaluate method, which recursively calls evaluate on it's children and then itself. passing the values or actions up the tree. 

 

You apparently have greatly underestimated what you're trying to do here ;)

I'm using the hawkins java parser.
In the C langage, the link between the script and the functions is
done through a function pointers array.
How does it work in java ?

Thanks for your help

You build a tree. Check out the example that's on Devin's Site:

Finally at the top you can either call an executable
