Detailed Description

DHCPv6 option space with enterprise number assigned.

This class extends the base class with the support for enterprise numbers. The enterprise numbers are assigned by IANA to various organizations and they are carried as uint32_t integers in DHCPv6 Vendor Specific Information Options (VSIO). For more information refer to RFC 8415. All option spaces that group VSIO options must have enterprise number set. It can be set using a constructor or setVendorSpace function. The extra functionality of this class (enterprise numbers) allows to represent DHCPv6 vendor-specific option spaces but this class is also intended to be used for all other DHCPv6 option spaces. That way all DHCPv6 option spaces can be stored in the container holding OptionSpace6 objects. Also, it is easy to mark vendor-specific option space as non-vendor specific option space (and the other way around) without a need to cast between OptionSpace and OptionSpace6 types.

Constructor & Destructor Documentation

OptionSpace6() [1/2]

isc::dhcp::OptionSpace6::OptionSpace6

(

const std::string &

name

)

Constructor for non-vendor-specific options.

This constructor marks option space as non-vendor specific.

Parameters

name	option space name.

Exceptions

isc::dhcp::InvalidOptionSpace

if given option space name contains invalid characters or is empty. This constructor uses OptionSpace::validateName function to check that the specified name is correct.

OptionSpace6() [2/2]

isc::dhcp::OptionSpace6::OptionSpace6	(	const std::string &	name,
		const uint32_t	enterprise_number )

Constructor for vendor-specific options.

This constructor marks option space as vendor specific and sets enterprise number to a given value.

Parameters

name	option space name.
enterprise_number	enterprise number.

Exceptions

isc::dhcp::InvalidOptionSpace

if given option space name contains invalid characters or is empty. This constructor uses OptionSpace::validateName function to check that the specified name is correct.
