Detailed Description

An IPv4 network.

Definition at line 718 of file IPRange.h.

Constructor & Destructor Documentation

IP4Net() [1/2]

swoc::IP4Net::IP4Net ( swoc::IP4Addr addr, swoc::IPMask mask )

inline

Construct from addr and mask.

Parameters

addr	An address in the network.
mask	The mask for the network.

The network is based on the mask, and the resulting network address is chosen such that the network will contain addr. For a given addr and mask there is only one network that satisifies these criteria.

Definition at line 2120 of file IPRange.h.

IP4Net() [2/2]

swoc::IP4Net::IP4Net ( swoc::TextView text )

inline

Definition at line 735 of file IPRange.h.

Member Function Documentation

as_range()

IP4Range swoc::IP4Net::as_range ( ) const

inline

Returns

A range that exactly covers the network.

Definition at line 2143 of file IPRange.h.

assign()

IP4Net::self_type & swoc::IP4Net::assign ( IP4Addr const & addr, IPMask const & mask )

inline

Assign an addr and mask to this.

Parameters

addr	Network addres.
mask	Network mask.

Returns

this.

Definition at line 2158 of file IPRange.h.

clear()

self_type & swoc::IP4Net::clear ( )

inline

Reset network to invalid state.

Definition at line 769 of file IPRange.h.

empty()

bool swoc::IP4Net::empty ( ) const

inline

Returns

true if the network contains no addresses (is invalid).

Definition at line 2128 of file IPRange.h.

load()

bool swoc::IP4Net::load

(

swoc::TextView

text

)

Parse network as text.

Parameters

text	String describing the network in CIDR format.

Returns

true if a valid string, false if not.

Definition at line 851 of file swoc_ip.cc.

mask()

IPMask const & swoc::IP4Net::mask ( ) const

inline

Returns

The mask for the network.

Definition at line 2123 of file IPRange.h.

max()

IP4Addr swoc::IP4Net::max ( ) const

inline

Returns

The largest address in the network.

Definition at line 2138 of file IPRange.h.

min()

IP4Addr swoc::IP4Net::min ( ) const

inline

Returns

Network address - smallest address in the network.

Definition at line 2133 of file IPRange.h.

operator!=()

bool swoc::IP4Net::operator!= ( self_type const & that ) const

inline

Inequality.

Definition at line 2153 of file IPRange.h.

operator==()

bool swoc::IP4Net::operator== ( self_type const & that ) const

inline

Equality.

Definition at line 2148 of file IPRange.h.
