Hi,
I'm a brand new ANTLR user. I'm using the AST tree it produces to
create an interpreter for a small subset of the Java programming
language. I was looking at the Main.java file in the grammar examples
directory, and one of the last lines says:
'
JavaTreeParser tparse = new JavaTreeParser();
try
{
tparse.compilationUnit(t);
System.err.println("successful walk of result
AST for "+f);
}
catch (RecognitionException e) {
System.err.println(e.getMessage());
e.printStackTrace();
}
' Could anyone tell me what this block does in the program, what is
a JavaTreeParser?
Thanks,
Jon
