				package org.codehaus.groovy.tools;
				
				public class GroovyClass

				    private String name;
				    private byte[] bytes;
				
				    public GroovyClass(String name,
				                       byte[] bytes)
				    {
				        this.name  = name;
				        this.bytes = bytes;
				    }
				
				    public String getName()
				    {
				        return this.name;
				    }
				
				    public byte[] getBytes()
				    {
