Member Function Documentation

evaluate()

unsigned isc::dhcp::TokenLeaseIA_PDSuboption::evaluate ( Pkt & pkt, ValueStack & values )

inlinevirtual

Evaluate the expression using the TokenSubOption implementation.

Parameters

pkt	specified parent option will be extracted from this packet
values	value of the sub-option will be pushed here (or "")

Returns

0 which means evaluate next token if any.

Reimplemented from isc::dhcp::TokenOption.

getOption()

virtual OptionPtr isc::dhcp::TokenLeaseIA_PDSuboption::getOption ( Pkt & pkt )

inlinevirtual

Get the IA_PD (25) option containing the OPTION_IAPREFIX (25) option matching the respective lease.

Parameters

pkt	The packet containing options.

Returns

A copy of the IA_PD option containing only one OPTION_IAPREFIX option (but all other options of different type) matching the respective lease or null if none exists.

Reimplemented from isc::dhcp::TokenLeaseIA_PD.
