Constructor & Destructor Documentation

◆ DdnsParams() [1/2]

isc::dhcp::DdnsParams::DdnsParams ( )

inline

Default constructor.

Definition at line 26 of file ddns_params.h.

◆ DdnsParams() [2/2]

isc::dhcp::DdnsParams::DdnsParams	(	const ConstSubnetPtr &	subnet,
		bool	d2_client_enabled )

Member Function Documentation

◆ getConflictResolutionMode()

std::string isc::dhcp::DdnsParams::getConflictResolutionMode ( ) const

Returns the DDNS config resolution mode for kea-dhcp-ddns.

This value is communicated to D2 via the NCR.

Returns: the DDNS conflict resolution mode

Definition at line 32 of file ddns_params.cc.

◆ getEnableUpdates()

bool isc::dhcp::DdnsParams::getEnableUpdates ( ) const

Returns whether or not DHCP DDNS updating is enabled.

The value is the logical AND of d2_client_enabled_ and the value returned by subnet_'s getDdnsSendUpdates().

Returns: True if updates are enabled, false otherwise or if subnet_ is empty.

Definition at line 975 of file srv_config.cc.

Referenced by isc::dhcp::D2ClientMgr::analyzeFqdn(), and isc::dhcp::Dhcpv4Srv::createNameChangeRequests().

◆ getGeneratedPrefix()

std::string isc::dhcp::DdnsParams::getGeneratedPrefix ( ) const

Returns the Prefix Kea should use when generating domain-names.

Returns: The value from the subnet_ or an empty string if subnet_ is empty.

Definition at line 1038 of file srv_config.cc.

Referenced by isc::dhcp::D2ClientMgr::generateFqdn().

◆ getHostnameCharReplacement()

std::string isc::dhcp::DdnsParams::getHostnameCharReplacement ( ) const

Returns the string to replace invalid characters when scrubbing hostnames.

Meaningful only if hostname_char_set_ is not empty.

Returns: The value from the subnet_ or an empty string if subnet_ is empty.

Definition at line 1079 of file srv_config.cc.

Referenced by getHostnameSanitizer().

◆ getHostnameCharSet()

std::string isc::dhcp::DdnsParams::getHostnameCharSet ( ) const

Returns the regular expression describing invalid characters for client hostnames.

If empty, host name scrubbing should not be done.

Returns: The value from the subnet_ or an empty string if subnet_ is empty.

Definition at line 1070 of file srv_config.cc.

Referenced by getHostnameSanitizer().

◆ getHostnameSanitizer()

util::str::StringSanitizerPtr isc::dhcp::DdnsParams::getHostnameSanitizer ( ) const

Returns a regular expression string sanitizer.

If the value returned by getHostnameCharSet() is not empty, then it is used in conjunction the value returned by getHostnameCharReplacment() (which may be empty) to create and return a StringSanitizer instance. Otherwise it will return an empty pointer.

Returns: pointer to the StringSanitizer instance or an empty pointer

Exceptions

BadValue if the compilation fails.
