Associated RRSIG methods
The associated RRSIG RRset is not supported in BasicRRset. For ease of use, getRRsig() returns a null pointer (indicating no RRset). The addRRsig()/removeRRsig() methods throw a "NotImplemented" exception - if you are using a BasicRRset, you should not be trying to modify signatures on it.

	Return pointer to this RRset's RRSIG RRset.
virtual uint32_t	getRRsigDataCount () const
	Returns the number of RRSIG records associated with the RRset.

Constructors and Destructor
Note: The copy constructor and the assignment operator are intentionally defined as private. The intended use case wouldn't require copies of a BasicRRset object; once created, it would normally be used as a const object (via references).
	BasicRRset (const Name &name, const RRClass &rrclass, const RRType &rrtype, const RRTTL &ttl)
	Constructor from (mostly) fixed parameters of the RRset.
virtual	~BasicRRset ()
	The destructor.

Detailed Description

The BasicRRset class is a concrete derived class of AbstractRRset that defines a straightforward RRset implementation.

This class is designed to be as portable as possible, and so it adopts the Pimpl idiom to hide as many details as possible. Performance is a secondary concern for this class.

This class is intended to be used by applications that only need moderate level of performance with full functionality provided by the AbstractRRset interfaces. Highly performance-sensitive applications, such as a large scale authoritative or caching name servers will implement and use a customized version of derived AbstractRRset class.

Constructor & Destructor Documentation

BasicRRset()

isc::dns::BasicRRset::BasicRRset	(	const Name &	name,
		const RRClass &	rrclass,
		const RRType &	rrtype,
		const RRTTL &	ttl )

Constructor from (mostly) fixed parameters of the RRset.

This constructor is normally expected to be exception free, but copying the name may involve resource allocation, and if it fails the corresponding standard exception will be thrown.

Parameters

name	The owner name of the RRset.
rrclass	The RR class of the RRset.
rrtype	The RR type of the RRset.
ttl	The TTL of the RRset.
