Detailed Description

template<typename CRC>
class FrameCPP::Common::cksum_impl< CRC >

Compute CRC checksum with length encoding.

---

This implements the calculation of a CRC checksum with

the addition of the number of bytes at the end.

Member Function Documentation

checksum() [1/2]

template<typename CRC >

value_type FrameCPP::Common::cksum_impl< CRC >::checksum ( ) const

inline

Retrieve the CRC value.

---

Returns

The calculated CRC value

checksum() [2/2]

template<typename CRC >

value_type FrameCPP::Common::cksum_impl< CRC >::checksum ( ) const

inline

Retrieve the CRC value.

---

Returns

The calculated CRC value

process_bytes() [1/2]

template<typename CRC >

void FrameCPP::Common::cksum_impl< CRC >::process_bytes ( void const * buffer, size_type byte_count )

inline

Updates the interim CRC.

---

Parameters

[in]	buffer	Buffer of bytes to be applied to the interim CRC
[in]	byte_count

Number of bytes in buffer to be applied to the interim CRC

process_bytes() [2/2]

template<typename CRC >

void FrameCPP::Common::cksum_impl< CRC >::process_bytes ( void const * buffer, size_type byte_count )

inline

Updates the interim CRC.

---

Parameters

[in]	buffer	Buffer of bytes to be applied to the interim CRC
[in]	byte_count

Number of bytes in buffer to be applied to the interim CRC

reset() [1/2]

template<typename CRC >

void FrameCPP::Common::cksum_impl< CRC >::reset ( )

inline

Allow the stucture to be reused.

---

This method resets the CRC state back to its initial configuration allowing it to be used to calculate

a new CRC checksum.

reset() [2/2]

template<typename CRC >

void FrameCPP::Common::cksum_impl< CRC >::reset ( )

inline

Allow the stucture to be reused.

---

This method resets the CRC state back to its initial configuration allowing it to be used to calculate

a new CRC checksum.
