Detailed Description

template<typename ParserBase>
class isc::host_cmds::HostDataParser< ParserBase >

A class for parsing extended host reservation data.

This template class provides a convenient interface for parsing extended host reservation data. Extended means that it is the typical host reservation as used in configuration file, with the addition of subnet-id parameter. It is not needed in the configuration file, because it's always obvious from the context (HR is defined in a subnet that has subnet-id). However, in reservation-add, reservation-del, reservation-update commands, the subnet-id parameter has to be specified explicitly.

Template Parameters

ParserBase

base class to be extended

Member Function Documentation

parseWithSubnet()

template<typename ParserBase>

isc::dhcp::HostPtr isc::host_cmds::HostDataParser< ParserBase >::parseWithSubnet ( isc::data::ConstElementPtr host_data, bool required = true )

inline

Parser specified parameter as host reservation data.

This method expects the input to be a ConstElementPtr tree structure that represents host reservation information. If parsing is successful, it returns HostPtr to the Host object that was created.

This method calls parse method from the ParserBase class. This method may throw additional exception types.

Parameters

host_data	Element tree to be parsed
required	True (default) if the subnet-id entry is required, false otherwise.

Returns

parsed host information

Exceptions

BadValue

if subnet-id is required but missing, or has invalid format.
