Detailed Description

Parser for DnsServerInfo.

This class parses the configuration element "dns-server" and creates an instance of a DnsServerInfo.

Definition at line 821 of file d2_config.h.

Member Function Documentation

parse()

DnsServerInfoPtr isc::d2::DnsServerInfoParser::parse	(	data::ConstElementPtr	server_config,
		data::ConstElementPtr	domain_config,
		const TSIGKeyInfoMapPtr	keys
	)

Performs the actual parsing of the given "dns-server" element.

Parses a configuration for the elements needed to instantiate a DnsServerInfo, validates those entries, creates a DnsServerInfo instance and returns it.

Parameters

server_config	is the "dns-server" configuration to parse
domain_config	the parent domain's configuration
keys	map of defined TSIG keys

Returns

a pointer to the newly created server instance

Exceptions

D2CfgError

if: hostname is not blank, hostname is not yet supported ip_address is invalid port is 0

Todo:

when resolvable hostname is supported we create the entry as follows:

// When  hostname is specified, create a valid, blank IOAddress
// and then create the DnsServerInfo.
serverInfo.reset(new DnsServerInfo(hostname, io_addr, port));

Resolution will be done prior to connection during transaction processing. Until then we'll throw unsupported.
