Detailed Description

A class for building IPv4 option records. This builder receives the IPv4 option parameters in its c'tor, builds the IPv4 option raw buffer and provides a build() method to get a IPv4Option object out of it

Constructor & Destructor Documentation

IPv4OptionBuilder() [1/4]

pcpp::IPv4OptionBuilder::IPv4OptionBuilder ( IPv4OptionTypes  optionType, const uint8_t *  optionValue, uint8_t  optionValueLen  )

inline

A c'tor for building IPv4 options which their value is a byte array. The IPv4Option object can be later retrieved by calling build()

Parameters

[in]	optionType	IPv4 option type
[in]	optionValue	A buffer containing the option value. This buffer is read-only and isn't modified in any way. For option types IPV4OPT_NOP and IPV4OPT_EndOfOptionsList this parameter is ignored (expected to be NULL) as these option types don't contain any data
[in]	optionValueLen	Option value length in bytes

IPv4OptionBuilder() [2/4]

pcpp::IPv4OptionBuilder::IPv4OptionBuilder ( IPv4OptionTypes  optionType, uint16_t  optionValue  )

inline

A c'tor for building IPv4 options which have a 2-byte value. The IPv4Option object can be later retrieved by calling build()

Parameters

[in]	optionType	IPv4 option type
[in]	optionValue	A 2-byte option value

IPv4OptionBuilder() [3/4]

pcpp::IPv4OptionBuilder::IPv4OptionBuilder	(	IPv4OptionTypes	optionType,
		const std::vector< IPv4Address > &	ipList
	)

A c'tor for building IPv4 options which their value is a list of IPv4 addresses, for example: IPV4OPT_RecordRoute, IPV4OPT_StrictSourceRoute, IPV4OPT_LooseSourceRoute. The IPv4Option object can be later retrieved by calling build()

Parameters

[in]	optionType	IPv4 option type
[in]	ipList	A vector of IPv4 addresses that will be used as the option value

IPv4OptionBuilder() [4/4]

pcpp::IPv4OptionBuilder::IPv4OptionBuilder ( const IPv4TimestampOptionValue &  timestampValue )

explicit

A c'tor for building IPv4 timestamp option (IPV4OPT_Timestamp). The IPv4Option object can be later retrieved by calling build()

Parameters

[in]

timestampValue

The timestamp value to build the IPv4 option with

const

Build the IPv4Option object out of the parameters defined in the c'tor

Returns

The IPv4Option object
