Detailed Description

A singleton class that creates, stores and provides access to all PcapLiveDevice (on Linux) or WinPcapLiveDevice (on Windows) instances. All live devices are initialized on startup and wrap the network interfaces installed on the machine. This class enables access to them through their IP addresses or get a vector of all of them so the user can search them in some other way

Member Function Documentation

getDnsServers()

const std::vector<IPv4Address>& pcpp::PcapLiveDeviceList::getDnsServers ( ) const

inline

Returns

A list of all DNS servers defined for this machine. If this list is empty it means no DNS servers were defined or they couldn't be extracted from some reason

getInstance()

static PcapLiveDeviceList& pcpp::PcapLiveDeviceList::getInstance ( )

inlinestatic

The access method to the singleton

Returns

The singleton instance of this class

getPcapLiveDeviceByIp() [1/4]

PcapLiveDevice* pcpp::PcapLiveDeviceList::getPcapLiveDeviceByIp

(

const IPAddress &

ipAddr

)

const

Get a pointer to the live device by its IP address. IP address can be both IPv4 or IPv6

Parameters

[in]

ipAddr

The IP address defined for the device

Returns

A pointer to the live device if this IP address exists. NULL otherwise

getPcapLiveDeviceByIp() [2/4]

PcapLiveDevice* pcpp::PcapLiveDeviceList::getPcapLiveDeviceByIp

(

const IPv4Address &

ipAddr

)

const

Get a pointer to the live device by its IPv4 address

Parameters

[in]

ipAddr

The IPv4 address defined for the device

Returns

A pointer to the live device if this IPv4 address exists. NULL otherwise

getPcapLiveDeviceByIp() [3/4]

PcapLiveDevice* pcpp::PcapLiveDeviceList::getPcapLiveDeviceByIp

(

const IPv6Address &

ip6Addr

)

const

Get a pointer to the live device by its IPv6 address

Parameters

[in]

ip6Addr

The IPv6 address defined for the device

Returns

A pointer to the live device if this IPv6 address exists. NULL otherwise

getPcapLiveDeviceByIp() [4/4]

PcapLiveDevice* pcpp::PcapLiveDeviceList::getPcapLiveDeviceByIp

(

const std::string &

ipAddrAsString

)

const

Get a pointer to the live device by its IP address represented as string. IP address can be both IPv4 or IPv6

Parameters

[in]

ipAddrAsString

The IP address defined for the device as string

Returns

A pointer to the live device if this IP address is valid and exists. NULL otherwise

getPcapLiveDeviceByIpOrName()

PcapLiveDevice* pcpp::PcapLiveDeviceList::getPcapLiveDeviceByIpOrName

(

const std::string &

ipOrName

)

const

Get a pointer to the live device by its IP address or name

Parameters

[in]

ipOrName

An IP address or name of the interface

Returns

A pointer to the live device if exists, NULL otherwise

getPcapLiveDeviceByName()

PcapLiveDevice* pcpp::PcapLiveDeviceList::getPcapLiveDeviceByName

(

const std::string &

name

)

const

Get a pointer to the live device by its name

Parameters

[in]

name

The name of the interface (e.g eth0)

Returns

A pointer to the live device if this name exists. NULL otherwise

getPcapLiveDevicesList()

const std::vector<PcapLiveDevice*>& pcpp::PcapLiveDeviceList::getPcapLiveDevicesList ( ) const

inline

Returns

A vector containing pointers to all live devices currently installed on the machine

reset()

void pcpp::PcapLiveDeviceList::reset

(

)

Reset the live device list and DNS server list, meaning clear and refetch them
