sameAs
boolean sameAs(DNSRecord other)
- True if this record is the same as some other record.
sameValue
abstract boolean sameValue(DNSRecord other)
- True if this record has the same value as some other record.
suppressedBy
boolean suppressedBy(DNSIncoming msg)
- True if this record is suppressed by the answers in a message.
suppressedBy
