Detailed Description

a common structure for IPv4 and IPv6 leases

This structure holds all information that is common between IPv4 and IPv6 leases.

Definition at line 31 of file lease.h.

Member Enumeration Documentation

◆ Type

enum isc::dhcp::Lease::Type

Type of lease or pool.

Enumerator
TYPE_NA	the lease contains non-temporary IPv6 address
TYPE_TA	the lease contains temporary IPv6 address
TYPE_PD	the lease contains IPv6 prefix (for prefix delegation)
TYPE_V4	IPv4 lease.

Definition at line 46 of file lease.h.

Constructor & Destructor Documentation

◆ Lease()

isc::dhcp::Lease::Lease	(	const isc::asiolink::IOAddress &	addr,
		uint32_t	valid_lft,
		SubnetID	subnet_id,
		time_t	cltt,
		const bool	fqdn_fwd,
		const bool	fqdn_rev,
		const std::string &	hostname,
		const HWAddrPtr &	hwaddr )

Constructor.

Parameters

addr	IP address
valid_lft	Lifetime of the lease
subnet_id	Subnet identification
cltt	Client last transmission time
fqdn_fwd	If true, forward DNS update is performed for a lease.
fqdn_rev	If true, reverse DNS update is performed for a lease.
hostname	FQDN of the client which gets the lease.
hwaddr	Hardware/MAC address

Note: When creating a new Lease object, current_cltt_ matches cltt_ and current_valid_lft_ matches valid_lft_. Any update operation that changes cltt_ or valid_lft_ in the database must also update the current_cltt_ and current_valid_lft_ after the database response so that additional operations can be performed on the same object. Failing to do so will result in the new actions to be rejected by the database.

Definition at line 43 of file lease.cc.

◆ ~Lease()

virtual isc::dhcp::Lease::~Lease ( )

inlinevirtual

Destructor.

◆ decline()

virtual void isc::dhcp::Lease::decline ( uint32_t probation_period )

pure virtual

Sets lease to DECLINED state.

All client identifying parameters will be stripped off (HWaddr, client_id, hostname), cltt will be set to current time and valid_lft to parameter specified as probation period. Note that This method only sets fields in the structure. It is caller's responsibility to clean up DDNS, bump up stats, log, call hooks ets.

Parameters

probation_period lease lifetime will be set to this value

Implemented in isc::dhcp::Lease4, and isc::dhcp::Lease6.

◆ expired()

bool isc::dhcp::Lease::expired ( ) const

returns true if the lease is expired

Returns: true if the lease is expired

◆ fromElementCommon()

void isc::dhcp::Lease::fromElementCommon	(	const LeasePtr &	lease,
		const data::ConstElementPtr &	element )

staticprotected

Sets common (for v4 and v6) properties of the lease object.

This method is called by the fromElement methods of the Lease class derivations.

Parameters
