Detailed Description

template<typename SubnetConfigParserType>
class isc::subnet_cmds::ConfigDiffManager< SubnetConfigParserType >

Manager which handles the delta (differences) between two subnets serialized as a JSON tree (usually a user provided subnet configuration and an already existing subnet configuration).

It uses an internal representation of the subnet parameters hierarchy to traverse the JSON tree, and functions to detect elements that match the same configuration element or to detect if the element itself is a key identifier of another configuration element. For more details, see isc::data::mergeDiffAdd isc::data::mergeDiffDel and isc::data::extend.

Template Parameters

SubnetConfigParserType

One of the Subnet4ConfigParser or Subnet6ConfigParser.

ConfigDiffManager()

template<typename SubnetConfigParserType>

isc::subnet_cmds::ConfigDiffManager< SubnetConfigParserType >::ConfigDiffManager ( std::string space )

inline

Constructor.

Parameters

space

The type of configuration to handle (dhcp4 or dhcp6).

function which returns true if there are no other parameters in the subnet beside the identification keys: 'id' and 'subnet'.

function which returns true if there are no other parameters in the pool beside the identification keys: 'pool' and an empty 'option-data'.

function which returns true if there are no other parameters in the pd-pool beside the identification keys: 'prefix', 'prefix-len', 'delegated-len' and an empty 'option-data'.

function which returns true if there are no other parameters in the option beside the identification keys: 'code' and 'name' and 'space'.

function which returns true for any pair of configuration elements.

function which returns true if the pair of subnet elements refer to the same subnet in the configuration.

function which returns true if the pair of pool elements refer to the same pool in the configuration.

function which returns true if the pair of pd-pool elements refer to the same pd-pool in the configuration.

function which returns true if the pair of option elements refer to the same option in the configuration.

function which returns true if the parameter name is an identification key for the subnet.

function which returns true if the parameter name is an identification key for the pool.

function which returns true if the parameter name is an identification key for the pd-pool.

function which returns true if the parameter name is an identification key for the option.

processDelta()

template<typename SubnetConfigParserType>

void isc::subnet_cmds::ConfigDiffManager< SubnetConfigParserType >::processDelta ( UpdateType type, ElementPtr & old_element, ConstElementPtr & subnet_element )

inline
