public NewsAddress(String newsgroup)
Construct a NewsAddress with the given newsgroup.

param
newsgroup the newsgroup

	this(newsgroup, null);
    
public NewsAddress(String newsgroup, String host)

	this.newsgroup = newsgroup;
	this.host = host;
    
Methods Summary
public booleanequals(java.lang.Object a)
The equality operator.

	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)));
    
public java.lang.StringgetHost()
Get the host.

return
host

	return host;
    
public java.lang.StringgetNewsgroup()
Get the newsgroup.

return
newsgroup

	return newsgroup;
    
public java.lang.StringgetType()
Return the type of this address. The type of a NewsAddress is "news".

	return "news";
    
public inthashCode()
Compute a hash code for the address.

	int hash = 0;
	if (newsgroup != null)
	    hash += newsgroup.hashCode();
	if (host != null)
	    hash += host.toLowerCase(Locale.ENGLISH).hashCode();
	return hash;
    
public static javax.mail.internet.NewsAddress[]parse(java.lang.String newsgroups)
Parse the given comma separated sequence of newsgroup into NewsAddress objects.

param
newsgroups comma separated newsgroup string
return
array of NewsAddress objects
exception
AddressException if the parse failed

	// 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;
    
public voidsetHost(java.lang.String host)
Set the host.

param
host the host

	this.host = host;
    
public voidsetNewsgroup(java.lang.String newsgroup)
Set the newsgroup.

param
newsgroup the newsgroup

	this.newsgroup = newsgroup;
    
public static java.lang.StringtoString(javax.mail.Address[] addresses)
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.

param
addresses array of NewsAddress objects
exception
ClassCastException, if any address object in the given array is not a NewsAddress objects. Note that this is a RuntimeException.
return
comma separated address strings

	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();
    
public java.lang.StringtoString()
Convert this address into a RFC 1036 address.

return
newsgroup

	return newsgroup;
