Detailed Description

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

Member Enumeration Documentation

NopEolOptionTypes

enum pcpp::TcpOptionBuilder::NopEolOptionTypes

An enum to describe NOP and EOL TCP options. Used in one of this class's c'tors

Enumerator
NOP	NOP TCP option
EOL	EOL TCP option

Constructor & Destructor Documentation

TcpOptionBuilder() [1/5]

pcpp::TcpOptionBuilder::TcpOptionBuilder ( TcpOptionType  optionType, const uint8_t *  optionValue, uint8_t  optionValueLen  )

inline

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

Parameters

[in]	optionType	TCP option type
[in]	optionValue	A buffer containing the option value. This buffer is read-only and isn't modified in any way.
[in]	optionValueLen	Option value length in bytes

TcpOptionBuilder() [2/5]

pcpp::TcpOptionBuilder::TcpOptionBuilder ( TcpOptionType  optionType, uint8_t  optionValue  )

inline

A c'tor for building TCP options which have a 1-byte value. The TcpOption object can be later retrieved by calling build()

Parameters

[in]	optionType	TCP option type
[in]	optionValue	A 1-byte option value

TcpOptionBuilder() [3/5]

pcpp::TcpOptionBuilder::TcpOptionBuilder ( TcpOptionType  optionType, uint16_t  optionValue  )

inline

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

Parameters

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

TcpOptionBuilder() [4/5]

pcpp::TcpOptionBuilder::TcpOptionBuilder ( TcpOptionType  optionType, uint32_t  optionValue  )

inline

A c'tor for building TCP options which have a 4-byte value. The TcpOption object can be later retrieved by calling build()

Parameters

[in]	optionType	TCP option type
[in]	optionValue	A 4-byte option value

TcpOptionBuilder() [5/5]

pcpp::TcpOptionBuilder::TcpOptionBuilder ( NopEolOptionTypes  optionType )

explicit

A c'tor for building TCP NOP and EOL options. These option types are special in that they contain only 1 byte which is the TCP option type (NOP or EOL). The TcpOption object can be later retrieved by calling build()

Parameters

[in]

optionType

An enum value indicating which option type to build (NOP or EOL)

Member Function Documentation

build()

TcpOption pcpp::TcpOptionBuilder::build

(

)

const

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

Returns

The TcpOption object
