## Detailed Description

Configuration Backend Manager for DHCPv6 servers.

Implements the "manager" class which holds information about the supported and configured backends and provides access to those backends. This is similar to `HostMgr` and `LeaseMgr` singletons being used by the DHCP servers.

It is implemented as a singleton that can be accessed from any place within the server code. This includes server configuration, data fetching during normal server operation and data management, including processing of control commands implemented within hooks libraries.

Unlike `HostMgr`, the it does not directly expose the API to fetch and manipulate the data in the database. This is done via, the Configuration Backend Pool, see `ConfigBackendPoolDHCPv6` for details.

## Member Function Documentation

## ◆ create()

void isc::dhcp::ConfigBackendDHCPv6Mgr::create | ( |  | ) |
| static

Creates new instance of the `ConfigBackendDHCPv6Mgr`.

If an instance of the `ConfigBackendDHCPv6Mgr` already exists, it will be replaced by the new instance. Thus, all factories will be unregistered and config databases will be dropped.

Definition at line 22 of file config_backend_dhcp6_mgr.cc.

## ◆ destroy()

void isc::dhcp::ConfigBackendDHCPv6Mgr::destroy | ( |  | ) |
| static

Destroys the instance of the `ConfigBackendDHCPv6Mgr`.

If an instance of the `ConfigBackendDHCPv6Mgr` exists, it will be destroyed. Thus, all factories will be unregistered and config databases will be dropped.

Definition at line 27 of file config_backend_dhcp6_mgr.cc.

## ◆ instance()

ConfigBackendDHCPv6Mgr & isc::dhcp::ConfigBackendDHCPv6Mgr::instance | ( |  | ) |
| static

Returns a sole instance of the `ConfigBackendDHCPv6Mgr`.

This method should be used to retrieve an instance of the `ConfigBackendDHCPv6Mgr` to be used to gather/manage config backends. It returns an instance of the `ConfigBackendDHCPv6Mgr` created by the `create` method. If the instance doesn't exist yet, it is created using the `create` method with the an empty set of configuration databases.
