Detailed Description

MySQL Host Context.

This class stores the thread context for the manager pool. The class is needed by all get/update/delete functions which must use one or more exchanges to perform database operations. Each context provides a set of such exchanges for each thread. The context instances are lazy initialized by the requesting thread by using the manager's createContext function and are destroyed when the manager's pool instance is destroyed.

◆ host_ipv46_exchange_

boost::shared_ptr<MySqlHostIPv6Exchange> isc::dhcp::MySqlHostContext::host_ipv46_exchange_

Pointer to an object representing an exchange which can be used to retrieve hosts, DHCPv4 and DHCPv6 options, and IPv6 reservations using a single query.

◆ host_ipv4_exchange_

boost::shared_ptr<MySqlHostWithOptionsExchange> isc::dhcp::MySqlHostContext::host_ipv4_exchange_

The exchange objects are used for transfer of data to/from the database.

They are pointed-to objects as the contents may change in "const" calls, while the rest of this object does not. (At alternative would be to declare them as "mutable".)

Pointer to an object representing an exchange which can be used to retrieve hosts and DHCPv4 options.
