Class IQReplyFilter

java.lang.Object

org.jivesoftware.smack.filter.IQReplyFilter

All Implemented Interfaces:

StanzaFilter

Direct Known Subclasses:

IQResultReplyFilter

public class IQReplyFilter
extends java.lang.Object
implements StanzaFilter

Filters for packets which are a valid reply to an IQ request.

Such a stanza(/packet) must have the same stanza(/packet) id and must be an IQ stanza(/packet) of type RESULT or ERROR. Moreover, it is necessary to check the from address to ignore forged replies.

We accept a from address if one of the following is true:

• It matches the to address of the request.
• The to address of the request was empty and the from address matches either the bare jid of the server or the (bare or full jid) of the client.
• To to was our bare address and the from is empty.

For a discussion of the issues, see the thread "Spoofing of iq ids and misbehaving servers" from 2014-01 on the jdev@jabber.org mailing list and following discussion in February and March.
