Detailed Description

Implementation of the mechanisms to control the use of the Configuration Backends by the DHCPv6 server.

It implements fetching and merging DHCPv6 server configuration from the database into the staging or current configuration.

Template Parameters

ConfigBackendMgrType

Type of the Config Backend Manager used by the server implementing this class. For example, for the DHCPv6 server it will be ConfigBackendDHCPv6Mgr.

Member Function Documentation

databaseConfigApply()

void isc::dhcp::CBControlDHCPv6::databaseConfigApply ( const db::BackendSelector & backend_selector, const db::ServerSelector & server_selector, const boost::posix_time::ptime & lb_modification_time, const db::AuditEntryCollection & audit_entries )

protectedvirtual

DHCPv6 server specific method to fetch and apply back end configuration into the local configuration.

Parameters

backend_selector	Backend selector.
server_selector	Server selector.
lb_modification_time	Lower bound modification time for the configuration elements to be fetched.
audit_entries	Audit entries fetched from the database since the last configuration update. This collection is empty if there were no updates.

Implements isc::process::CBControlBase< ConfigBackendMgrType >.
