Detailed Description

Parser for IPv4 pool definitions.

This is the IPv4 derivation of the PoolParser class and handles pool definitions, i.e. a list of entries of one of two syntaxes: min-max and prefix/len for IPv4 pools. Pool4 objects are created and stored in chosen PoolStorage container.

It is useful for parsing Dhcp4/subnet4[X]/pool parameters.

Member Function Documentation

◆ poolMaker() [1/2]

PoolPtr isc::dhcp::Pool4Parser::poolMaker	(	asiolink::IOAddress &	addr,
		uint32_t	len,
		int32_t	ignored
	)

protectedvirtual

Creates a Pool4 object given a IPv4 prefix and the prefix length.

Parameters

addr	is the IPv4 prefix of the pool.
len	is the prefix length.
ignored	dummy parameter to provide symmetry between the PoolParser derivations. The V6 derivation requires a third value.

Returns: returns a PoolPtr to the new Pool4 object.

Implements isc::dhcp::PoolParser.

Definition at line 527 of file dhcp_parsers.cc.

◆ poolMaker() [2/2]

PoolPtr isc::dhcp::Pool4Parser::poolMaker	(	asiolink::IOAddress &	min,
		asiolink::IOAddress &	max,
		int32_t	ignored
	)

protectedvirtual

Creates a Pool4 object given starting and ending IPv4 addresses.

Parameters

min	is the first IPv4 address in the pool.
max	is the last IPv4 address in the pool.
ignored	dummy parameter to provide symmetry between the PoolParser derivations. The V6 derivation requires a third value.

Returns: returns a PoolPtr to the new Pool4 object.

Implements isc::dhcp::PoolParser.
