Detailed Description

base class for Pool4 and Pool6

Stores information about pool of IPv4 or IPv6 addresses. That is a basic component of a configuration.

Definition at line 30 of file pool.h.

Constructor & Destructor Documentation

◆ ~Pool()

virtual isc::dhcp::Pool::~Pool ( )

inlinevirtual

virtual destructor

We need Pool to be a polymorphic class, so we could dynamic cast from PoolPtr to Pool6Ptr if we need to. A class becomes polymorphic, when there is at least one virtual method.

Definition at line 78 of file pool.h.

◆ Pool()

isc::dhcp::Pool::Pool	(	Lease::Type	type,
		const isc::asiolink::IOAddress &	first,
		const isc::asiolink::IOAddress &	last
	)

protected

protected constructor

This constructor is protected to prevent anyone from instantiating Pool class directly. Instances of Pool4 and Pool6 should be created instead.

Parameters

type	type of lease that will be served from this pool
first	first address of a range
last	last address of a range

Definition at line 21 of file pool.cc.

◆ capacity_

uint64_t isc::dhcp::Pool::capacity_

This could be calculated on the fly, but the calculations are somewhat involved, so it is more efficient to calculate it once and just store the result. Note that for very large pools, the number is capped at max value of uint64_t.
