org.apache.directory.server.dns.messages.ResourceRecordImpl

All Implemented Interfaces:

ResourceRecord

public class ResourceRecordImpl
extends java.lang.Object
implements ResourceRecord

The answer, authority, and additional sections all share the same format: a variable number of resource records, where the number of records is specified in the corresponding count field in the header. Each resource record has the following format: 1 1 1 1 1 1 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | | / / / NAME / | | +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | TYPE | +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | CLASS | +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | TTL | | | +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | RDLENGTH | +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--| / RDATA / / / +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+

Field Detail

domainName

private java.lang.String domainName

An owner name, i.e., the name of the node to which this resource record pertains.

recordType

private RecordType recordType

Two octets containing one of the resource record TYPE codes.

recordClass

private RecordClass recordClass

Two octets containing one of the resource record CLASS codes. For example, the CLASS field is IN for the Internet.

timeToLive

private int timeToLive

A 32 bit signed integer that specifies the time interval that the resource record may be cached before the source of the information should again be consulted. Zero values are interpreted to mean that the resource record can only be used for the transaction in progress, and should not be cached. For example, SOA records are always distributed with a zero TTL to prohibit caching. Zero values can also be used for extremely volatile data.

attributes

private java.util.Map<java.lang.String,java.lang.Object> attributes

A variable length string of octets that describes the resource. The format of this information varies according to the TYPE and CLASS of the resource record.
