public class SemanticSkeletonGenerator

extends java.lang.Object

This class can be called using SourceGenerator by commandline.

Generates Java code that contains empty method bodies for the implementation of a given Syntax. For every rule there will be a method with the name of the nonterminal on the left side and one argument for each symbol on the right side. All arguments are of type Object. The created implementation derives ReflectSemantic.

                File in = new File("MySyntax.grammar);
                String basename = "MySemantic";
                Writer out = new FileWriter(basename+".java");
                new SemanticSkeletonGenerator(in, basename, "my.pkg.name", out);
                // the Java source "my/pkg/name/MySemantic.java" will be generated

                          throws java.lang.Exception

Reads the passed Syntax and turns it into a semantic skeleton implementation. The passed Write will be closed.

Parameters:

syntax - Syntax the semantc is meant for

className - basname of the class to generate (without package)

pkgName - name of package, can be null

skeletonOutput - Writer where Java source should be written to
