Method Details

rrFromWire

protected void rrFromWire(DNSInput in)
                   throws IOException

Description copied from class: Record

Converts the type-specific RR to wire format - must be overridden

Specified by:

rrFromWire in class Record

Throws:

IOException

rdataFromString

protected void rdataFromString(Tokenizer st,
 Name origin)
                        throws IOException

Description copied from class: Record

Converts the text format of an RR to the internal format - must be overriden

Specified by:

rdataFromString in class Record

Throws:

IOException

rrToString

protected String rrToString()

Converts the RRSIG/SIG Record to a String

Specified by:

rrToString in class Record

getTypeCovered

public int getTypeCovered()

Returns the RRset type covered by this signature

getRRsetType

public int getRRsetType()

Returns the type of RRset that this record would belong to. For all types except SIG/RRSIG, this is equivalent to getType().

Overrides:

getRRsetType in class Record

Returns:

The type of record

• Type
• RRset
• Record.getRRsetType()

getAlgorithm

public int getAlgorithm()

Returns the cryptographic algorithm of the key that generated the signature

getLabels

public int getLabels()

Returns the number of labels in the signed domain name. This may be different than the record's domain name if the record is a wildcard record.

getOrigTTL

public long getOrigTTL()

Returns the original TTL of the RRset

getExpire

public Instant getExpire()

Returns the time at which the signature expires

getTimeSigned

public Instant getTimeSigned()

Returns the time at which this signature was generated

getFootprint

public int getFootprint()

Returns the footprint/key id of the signing key.

getSigner

public Name getSigner()

Returns the owner of the signing key

getSignature

public byte[] getSignature()

Returns the binary data representing the signature

setSignature

void setSignature(byte[] signature)

rrToWire

protected void rrToWire(DNSOutput out,
 Compression c,
 boolean canonical)

Description copied from class: Record

Converts the type-specific RR to wire format - must be overridden.

Specified by:

rrToWire in class Record
