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_listpointer to an element that holds entries for client class definitions.
familythe address family of the client class definitions.
check_dependenciesindicates if the parser should evaluate an expression to see if the referenced client classes exist.
Returns
a pointer to the filled dictionary
Exceptions
DhcpConfigErrorif configuration parsing fails.
