Detailed Description

Acts as a storage vault for D2 client configuration.

A simple container class for storing and retrieving the configuration parameters associated with DHCP-DDNS and acting as a client of D2. Instances of this class may be constructed through configuration parsing.

	)

Constructor.

Parameters

enable_updates	Enables DHCP-DDNS updates
server_ip	IP address of the kea-dhcp-ddns server (IPv4 or IPv6)
server_port	IP port of the kea-dhcp-ddns server
sender_ip	IP address of the kea-dhcp-ddns server (IPv4 or IPv6)

Member Function Documentation

void isc::dhcp::D2ClientConfig::enableUpdates ( bool enable )

Sets enable-updates flag to the given value.

This is the only value that may be altered outside the constructor as it may be desirable to toggle it off and on when dealing with D2 IO errors.

Parameters

enable boolean value to assign to the enable-updates flag

Definition at line 118 of file d2_client_cfg.cc.

bool isc::dhcp::D2ClientConfig::getEnableUpdates ( ) const

inline

Return whether or not DHCP-DDNS updating is enabled.

Definition at line 114 of file d2_client_cfg.h.

size_t isc::dhcp::D2ClientConfig::getMaxQueueSize ( ) const

inline

Return Maximum sender queue size.

Definition at line 139 of file d2_client_cfg.h.

const dhcp_ddns::NameChangeFormat& isc::dhcp::D2ClientConfig::getNcrFormat ( ) const

inline

Return the kea-dhcp-ddns request format.

Definition at line 149 of file d2_client_cfg.h.

const dhcp_ddns::NameChangeProtocol& isc::dhcp::D2ClientConfig::getNcrProtocol ( ) const

std::string isc::dhcp::D2ClientConfig::replaceClientNameModeToString ( const ReplaceClientNameMode & mode )

static

Converts NameChangeFormat enums to text labels.

Parameters

mode	enum value to convert to label

Returns: std:string containing the text label if the value is valid, or "unknown" if not.

Definition at line 63 of file d2_client_cfg.cc.

D2ClientConfig::ReplaceClientNameMode isc::dhcp::D2ClientConfig::stringToReplaceClientNameMode ( const std::string & mode_str )

static

Converts labels to ReplaceClientNameMode enum values.

Parameters

mode_str text to convert to an enum. Valid string values: "never", "always", "when-present", "when-not-present" (case-insensitive)

Returns: NameChangeFormat value which maps to the given string.

Exceptions

isc::BadValue if given a string value which does not map to an enum value.
