Detailed Description

A class that represents generic DNS RR data which cannot be represented in any of the other classes. It stores the DNS RR data as byte array

Constructor & Destructor Documentation

GenericDnsResourceData() [1/3]

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

A c'tor for this class

Parameters

[in]	dataPtr	A byte array that contains the raw data (as it written in the DNS packet). The data will be copied from this byte array to the object
[in]	dataLen	The byte array size

GenericDnsResourceData() [2/3]

pcpp::GenericDnsResourceData::GenericDnsResourceData ( const std::string &  dataAsHexString )

explicit

A c'tor for this class

Parameters

[in]

dataAsHexString

A hex string that represents the DNS RR data

GenericDnsResourceData() [3/3]

pcpp::GenericDnsResourceData::GenericDnsResourceData

(

const GenericDnsResourceData &

other

)

A copy c'tor for this class

Parameters

[in]

other

The instance to copy from

Member Function Documentation

operator==()

bool pcpp::GenericDnsResourceData::operator==

(

const GenericDnsResourceData &

other

)

const

Equality operator overload for this class that compares the raw data stored in each object

Parameters

[in]

other

The object to compare with

Returns

True if data is the same in both objects, meaning byte streams are equal, false otherwise

toByteArr()

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

virtual

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::GenericDnsResourceData::toString ( ) const

virtual

Returns

A string that represents the current DNS RR data

Implements pcpp::IDnsResourceData.
