Interface AddressResolver

All Known Implementing Classes:

DefaultAddressResolver

public interface AddressResolver

An interface that allows you to customize address lookup. The user can implement this interface to do DNS lookups or other lookup schemes and register it with the stack. The default implementation of the address resolver does nothing more than just return back the Hop that it was passed (fixing up the port if necessary). However, this behavior can be overriden. To override implement this interface and register it with the stack using SipStackExt.setAddressResolver(AddressResolver). This interface will be incorporated into version 2.0 of the JAIN-SIP Specification.

2.0
