Examples of DNSLookupContinuation

org.apache.james.jspf.core.DNSLookupContinuation
This object is used as the return value for spf resolving tasks. Every time a DNS resolution is needed the task should simply return this one including the DNSRequest and a listener to be invoked when the answer will be available.
