Detailed Description

A node in the DNS tree.

Constructor & Destructor Documentation

DNSNode::DNSNode ( )

inline

DNSNode::DNSNode ( const DNSLabel &  lab, DNSNode *  parent  )

inline

DNSNode::~DNSNode ( )

default

Member Function Documentation

DNSNode * DNSNode::add

(

DNSName

name

)

This is an idempotent way to add a node to a DNS tree.

Idempotent way of creating/accessing the DNSName in a tree.

Here is the call graph for this function:

void DNSNode::addRRs

(

std::unique_ptr< RRGen > &&

a

)

add one RRGen to this node

template<typename... Types>

void DNSNode::addRRs ( std::unique_ptr< RRGen > &&  a, Types &&...  args  )

inline

add multiple RRGen to this node

Here is the call graph for this function:

const DNSNode * DNSNode::find	(	DNSName &	name,
		DNSName &	last,
		bool	wildcards = false,
		const DNSNode **	passedZonecut = 0,
		const DNSNode **	passedWcard = 0
	)		const

This is the key function that finds names, returns where it found them and if any zonecuts were passsed.

The big RFC 1034-compatible find function. Will perform wildcard synth if requested & let you know about it.

Here is the call graph for this function:

DNSName DNSNode::getName ( ) const

Here is the call graph for this function:

const DNSNode * DNSNode::next

const DNSNode * DNSNode::prev

Member Data Documentation

std::set<DNSNode, DNSNodeCmp> DNSNode::children

children, found by DNSLabel

DNSLabel DNSNode::d_name

DNSNode* DNSNode::d_parent {0}

uint16_t DNSNode::namepos {0}

for label compression, we also use DNSNodes

std::map<DNSType, RRSet > DNSNode::rrsets

std::unique_ptr<DNSNode> DNSNode::zone

if this is set, this node is a zone
