Detailed Description

A wrapper class for NFLOG TLV fields. This class does not create or modify TLVs related to NFLOG, but rather serves as a wrapper and provides useful methods for setting and retrieving data to/from them

Constructor & Destructor Documentation

NflogTlv()

pcpp::NflogTlv::NflogTlv ( uint8_t *  recordRawData )

inlineexplicit

A c'tor for this class that gets a pointer to the option raw data (byte array)

Parameters

[in]

recordRawData

A pointer to the option raw data

Member Function Documentation

assign()

void pcpp::NflogTlv::assign ( uint8_t *  recordRawData )

inline

Assign a pointer to the TLV record raw data (byte array)

Parameters

[in]

recordRawData

A pointer to the TLV record raw data

canAssign()

static bool pcpp::NflogTlv::canAssign ( const uint8_t *  recordRawData, size_t  tlvDataLen  )

inlinestatic

Check if a pointer can be assigned to the TLV record data

Parameters

[in]	recordRawData	A pointer to the TLV record raw data
[in]	tlvDataLen	The size of the TLV record raw data

Returns

True if data is valid and can be assigned

getRecordBasePtr()

uint8_t* pcpp::NflogTlv::getRecordBasePtr ( ) const

inline

Returns

A pointer to the TLV record raw data byte stream

getTotalSize()

size_t pcpp::NflogTlv::getTotalSize ( ) const

inline

Returns

recordLen attribute in NflogTLVRawData

getType()

uint16_t pcpp::NflogTlv::getType ( ) const

inline

Returns

The type field of the record (the 'T' in Type-Length-Value)

getValue()

uint8_t* pcpp::NflogTlv::getValue ( ) const

inline

Returns

A pointer to the value of the record as byte array (the 'V' in Type-Length- Value)

isNull()

bool pcpp::NflogTlv::isNull ( ) const

inline

Returns

True if the TLV record raw data is nullptr, false otherwise
