com.ph.pr.parser.vbs2java
Class VBSVisitor

java.lang.Object
  extended by com.ph.pr.parser.ReflectiveVisitor
      extended by com.ph.pr.parser.vbs2java.VBSVisitor
All Implemented Interfaces:
Visitor
public class VBSVisitor
extends ReflectiveVisitor

Translates a VBScript script into a Java class.

Notice that this was generated with the first draft of ASTBuilder, which had a little issue due to the silliness of the author. As a result, getters and setters for non-terminals in each implementation of ASTNodeare still used (whereas the fix is to use ASTNode.getNodes()). The ambiguous cases here have been fixed manually (such as visit(expr_7_AST)and similar ones).

A given VBScript script is translated into a Java class. Sample usage is: ASTNode start = ASTBuilder.singleton().parse(null, "com.sun.foo", "XXX.vbs");
VBSVisitor visitor = new VBSVisitor();
start.accept(visitor);
String code = visitor.getCode();

After which the code variable will contain the body of the class, without the class signature, package statements or imports. It currently the job of the caller (in our case, com.ph.pr.parser.vb2java.achapps.VBS2Java) to fill that out. However, the resulting class must import everything in this package, and extend com.ph.pr.parser.vb2java.VBS2JavaBase(or a subclass thereof).

Also, since we're only concerned with cases that appear in our VBScript files, some functionality of VBScript is not handled; the corresponding branches of its visit() methods throw UnsupportedOperationException.
