public NewsAddress() 
{

}

Default constructor.

 public NewsAddress(String newsgroup) 
{
	this(newsgroup, null);
}

Construct a NewsAddress with the given newsgroup.

Parameters:

newsgroup - the newsgroup

 public NewsAddress(String newsgroup,
    String host) 
{
	this.newsgroup = newsgroup;
	this.host = host;
}

Construct a NewsAddress with the given newsgroup and host.

Parameters:

newsgroup - the newsgroup

host - the host

 public boolean equals(Object a) 
{
	if (!(a instanceof NewsAddress))
	    return false;
	NewsAddress s = (NewsAddress)a;
	return newsgroup.equals(s.newsgroup) &&
	    ((host == null && s.host == null) ||
	     (host != null && s.host != null && host.equalsIgnoreCase(s.host)));
}

The equality operator.

 public String getHost() 
{
	return host;
}

Get the host.

 public String getNewsgroup() 
{
	return newsgroup;
}

Get the newsgroup.

 public String getType() 
{
	return "news";
}

Return the type of this address. The type of a NewsAddress is "news".

 public int hashCode() 
{
	int hash = 0;
	if (newsgroup != null)
	    hash += newsgroup.hashCode();
	if (host != null)
	    hash += host.toLowerCase(Locale.ENGLISH).hashCode();
	return hash;
}

Compute a hash code for the address.

 public static NewsAddress[] parse(String newsgroups) throws AddressException 
{
	// XXX - verify format of newsgroup name?
	StringTokenizer st = new StringTokenizer(newsgroups, ",");
	Vector nglist = new Vector();
	while (st.hasMoreTokens()) {
	    String ng = st.nextToken();
	    nglist.addElement(new NewsAddress(ng));
	}
	int size = nglist.size();
	NewsAddress[] na = new NewsAddress[size];
	if (size  > 0)
	    nglist.copyInto(na);
	return na;
}

Parse the given comma separated sequence of newsgroup into NewsAddress objects.

 public  void setHost(String host) 
{
	this.host = host;
}

Set the host.

 public  void setNewsgroup(String newsgroup) 
{
	this.newsgroup = newsgroup;
}

Set the newsgroup.

 public String toString() 
{
	return newsgroup;
}

Convert this address into a RFC 1036 address.

 public static String toString(Address[] addresses) 
{
	if (addresses == null || addresses.length == 0)
	    return null;
	StringBuffer s = 
		new StringBuffer(((NewsAddress)addresses[0]).toString());
	for (int i = 1; i <  addresses.length; i++)
	    s.append(",").append(((NewsAddress)addresses[i]).toString());
	return s.toString();
}

Convert the given array of NewsAddress objects into a comma separated sequence of address strings. The resulting string contains only US-ASCII characters, and hence is mail-safe.
