Detailed Description

template<typename ConfigBackendMgrType>
class isc::dhcp::CBControlDHCP< ConfigBackendMgrType >

Base class for implementing mechanisms to control the use of the Configuration Backends by DHCPv4 and DHCPv6 servers.

It includes common methods used by the DHCPv4 and DHCPv6 specific derivations.

Template Parameters

ConfigBackendMgrType

Type of the Config Backend Manager used by the server implementing this class. For example, for the DHCPv4 server it will be ConfigBackendDHCPv4Mgr.

Member Function Documentation

translateAndAddGlobalsToConfig()

template<typename ConfigBackendMgrType >

void isc::dhcp::CBControlDHCP< ConfigBackendMgrType >::translateAndAddGlobalsToConfig ( SrvConfigPtr external_cfg, data::StampedValueCollection & cb_globals ) const

inlineprotected

It translates the top level map parameters from flat naming format (e.g.

param-name.sub-param-name) to proper ElementMap objects and adds all globals fetched from config backend(s) to a SrvConfig instance

Iterates over the given collection of global parameters and adds them to the given configuration's list of configured globals.

Parameters

external_cfg	SrvConfig instance to update
cb_globals	collection of global parameters supplied by configuration backend

template<typename ConfigBackendMgrType >

static bool isc::dhcp::CBControlDHCP< ConfigBackendMgrType >::translateName ( std::string const & name, std::string & param_name, std::string & sub_param_name )

inlinestatic

It translates the top level map parameters from flat naming format (e.g.

param-name.sub-param-name) to the respective param-name and sub-param-name. If the name does not contain '.', the param-name will contain the initial name.

Parameters

	name	The name in flat format (e.g. map-name.element-name).
[out]	param_name	The resulting top level param name.
[out]	sub_param_name	The resulting sub param name inside the map.

Returns

The function returns true if any conversion is done, false otherwise.
