## Detailed Description

Parser for a list of client class definitions.

This parser iterates over all configuration entries that define client classes and creates ClientClassDef instances for each. When the parsing successfully completes, the collection of created definitions is given to the CfgMgr.

## Member Function Documentation

## ◆ parse()

ClientClassDictionaryPtr isc::dhcp::ClientClassDefListParser::parse | ( | isc::data::ConstElementPtr | class_def_list,
|  | uint16_t | family,
|  | bool | check_dependencies = true )

Parse configuration entries.

This function parses configuration entries, creates instances of client class definitions and tries to adds them to the local dictionary. At the end the dictionary is returned.

Parameters

  class_def_list | pointer to an element that holds entries for client class definitions.
  family | the address family of the client class definitions.
  check_dependencies | indicates if the parser should evaluate an expression to see if the referenced client classes exist.

Returns
  a pointer to the filled dictionary

Exceptions

  DhcpConfigError | if configuration parsing fails.
