Detailed Description

A class that represents DNS RR IPv4 data, mainly used in DNS RRs of type DNS_TYPE_A

Constructor & Destructor Documentation

IPv4DnsResourceData() [1/3]

pcpp::IPv4DnsResourceData::IPv4DnsResourceData	(	const uint8_t *	dataPtr,
		size_t	dataLen
	)

A c'tor for this class

Parameters

[in]	dataPtr	A byte array of size 4 that contains an IPv4 address (each byte represents 1 octet)
[in]	dataLen	The byte array size, expected to be 4

IPv4DnsResourceData() [2/3]

pcpp::IPv4DnsResourceData::IPv4DnsResourceData ( const IPv4Address &  addr )

inlineexplicit

A c'tor for this class

Parameters

[in]

addr

The IPv4 address to store in this object

IPv4DnsResourceData() [3/3]

pcpp::IPv4DnsResourceData::IPv4DnsResourceData ( const std::string &  addrAsString )

inlineexplicit

A c'tor for this class

Parameters

[in]

addrAsString

A string representation of an IPv4 address to store in this object

Member Function Documentation

getIpAddress()

IPv4Address pcpp::IPv4DnsResourceData::getIpAddress ( ) const

inline

Returns

The IPv4 address stored in this object

operator==()

bool pcpp::IPv4DnsResourceData::operator== ( const IPv4DnsResourceData &  other ) const

inline

Equality operator overload for this class that compares the IPv4 addresses stored in each object

Parameters

[in]

other

The object to compare with

Returns

True if IPv4 addresses are the same in both objects, false otherwise

toByteArr()

bool pcpp::IPv4DnsResourceData::toByteArr ( uint8_t *  arr, size_t &  arrLength, IDnsResource *  dnsResource  ) const

overridevirtual

Convert the DNS RR data into a byte array

Parameters

[out]	arr	A pointer to a pre-allocated byte array where the result will be written to
[out]	arrLength	A reference to a 2-byte number where the result array length will be written to
[in]	dnsResource	A pointer to a DNS resource object where this DNS RR data will be stored

Returns

True if the DNS RR data was successfully converted into a byte array and written to the given array or false if stored DNS RR data is invalid or if it could not be written to the given array

Implements pcpp::IDnsResourceData.

toString()

std::string pcpp::IPv4DnsResourceData::toString ( ) const

inlineoverridevirtual

Returns

A string that represents the current DNS RR data

Implements pcpp::IDnsResourceData.
