        return lookupTypeKey;
    }

    public void setLookupTypeKey(String key)
    {
        this.lookupTypeKey = key;
    }

    public List getLookupValues()
    {
        return lookupValueList;
    }

    public void addLookupValue(LookupLine line)
    {
        if (lookupValueList == null)
        {
            lookupValueList = new ArrayList();
        }
        lookupValueList.add(line);
    }
}

public class LookupLine 
{
    protected Long lookupValueId;
    protected LookupHeader lookupHeader;

    public Long getLookupValueId()
    {
        return lookupValueId;
