Detailed Description

The IOAddress class represents an IP addresses (version agnostic)

This class is a wrapper for the ASIO ip::address class.

Constructor & Destructor Documentation

IOAddress() [1/3]

isc::asiolink::IOAddress::IOAddress

(

const std::string &

address_str

)

Constructor from string.

This constructor converts a textual representation of IPv4 and IPv6 addresses into an IOAddress object. If address_str is not a valid representation of any type of address, an exception of class IOError will be thrown. This constructor allocates memory for the object, and if that fails a corresponding standard exception will be thrown.

Parameters

address_str

Textual representation of address.

Definition at line 38 of file io_address.cc.

References isc_throw.

IOAddress() [2/3]

isc::asiolink::IOAddress::IOAddress

(

const boost::asio::ip::address &

asio_address

)

Constructor from an ASIO ip::address object.

This constructor is intended to be used within the wrapper implementation; user applications of the wrapper API won't use it.

This constructor never throws an exception.

Parameters

asio_address

The ASIO ip::address to be converted.

Definition at line 47 of file io_address.cc.

IOAddress() [3/3]

isc::asiolink::IOAddress::IOAddress

(

uint32_t

v4address

)

Constructor for ip::address_v4 object.

This constructor is intended to be used when constructing IPv4 address out of uint32_t type. Passed value must be in host byte order.

Parameters

v4address

IPv4 address represented by uint32_t

Definition at line 51 of file io_address.cc.

Member Function Documentation

equals()

bool isc::asiolink::IOAddress::equals ( const IOAddress &  other ) const

inline

Compare addresses for equality.

Parameters

other

Address to compare against.

Returns

true if addresses are equal, false if not.

Definition at line 176 of file io_address.h.

fromBytes()

IOAddress isc::asiolink::IOAddress::fromBytes ( short  family, const uint8_t *  data  )

static

Parameters

family	AF_INET for IPv4 or AF_INET6 for IPv6.
data	pointer to first char of data

Returns

Created IOAddress object

getFamily()

short isc::asiolink::IOAddress::getFamily

(

)

const

Returns the address family.

Returns

AF_INET for IPv4 or AF_INET6 for IPv6.

increase()

IOAddress isc::asiolink::IOAddress::increase ( const IOAddress &  addr )

static

Returns an address increased by one.

This method works for both IPv4 and IPv6 addresses. For example, increase 192.0.2.255 will become 192.0.3.0.

Address space is a finite field in the mathematical sense, so keep in mind that the address space "loops". 255.255.255.255 increased by one gives 0.0.0.0. The same is true for maximum value of IPv6 (all 1's) looping to ::.

Todo:

Determine if we have a use-case for increasing the address by more than one. Increase by one is used in AllocEngine. This method could take extra parameter that specifies the value by which the address should be increased.

Parameters

addr	address to be increased

Returns

address increased by one

Here is the call graph for this function:

subtract()

IOAddress isc::asiolink::IOAddress::subtract ( const IOAddress &  a, const IOAddress &  b  )

static

Subtracts one address from another (a - b)

Treats addresses as integers and subtracts them. For example:

192.0.2.5 - 192.0.2.0 = 0.0.0.5
fe80::abcd - fe80:: = ::abcd

It is possible to subtract greater from lesser address, e.g. 192.168.56.10 - 192.168.67.20, but please do understand that the address space is a finite field in mathematical sense, so you may end up with a result that is greater then any of the addresses you specified. Also, subtraction is not commutative, so a - b != b - a.

This operation is essential for calculating the number of leases in a pool, where we need to calculate (max - min).

Exceptions

BadValue

if addresses are of different family

Parameters

a	address to be subtracted from
b	address to be subtracted

Returns

IOAddress object that represents the difference
