Method Detail

clone

public java.lang.Object clone()

Overrides Cloneable.

Overrides:

clone in class java.lang.Object

Returns:

a clone of this instance.

Throws:

OutOfMemoryError - if there is not enough memory.

Cloneable

setDebug

public void setDebug(boolean b)

Toggle debug status.

Parameters:

b - boolean.

buildPacket

public byte[] buildPacket(DNSName dnsname,
                          int globalIdx)
                   throws DNSNameException

Build and return the rdata packet on the internal state.

Parameters:

dnsname - used for domain name compression in the same message.

globalIdx - current index of the message being assembled. (Domain name compression)

Returns:

the rdata part of the message as a byte array.

Throws:

DNSNameException - if the domain name is invalid.

getDisassembledLen

public int getDisassembledLen()

Returns the length of the previously disassembled rdata part.

See Also:

disassemblePacket(DNSName, byte[], int, int)

disassemblePacket

public void disassemblePacket(DNSName dnsname,
                              byte[] pDat,
                              int pIdx,
                              int pLen)
                       throws DNSNameException,
                              DNSRDataException

Parses the rdata part of a record.

Parameters:

dnsname - used for domain name compression in the same message.

pDat - array containing the complete packet.

pIdx - index to where in the array the rdata part begins.

pLen - length of the whole packet.

Throws:

DNSRDataException - if the packet is corrupted.

DNSNameException - if the domain name is invalid.

getRType

public int getRType()

Get the record type.

Returns:

record type.

toString

public java.lang.String toString()

Returns a string representation of the internal state, mostly for debugging purposes.

Overrides:

toString in class java.lang.Object

Returns:

debug string.
