Detailed Description

Implementation of MurmurHash3 32-bit x32 hash.

This algorithm is the 32-bit MurmurHash3 hash, by Austin Appleby. It is optimized for 32-bit architectures.

The code here is adapted from the smhasher project at https://github.com/aappleby/smhasher. It has been placed in the public domain by the author.

No care has been taken to work with different endianness, etc, since that is beyond the scope of the project.

Member Function Documentation

HashValue bphash::detail::MurmurHash3_32_x32::finalize ( void  )

virtual

Finish hashing and report the hash.

Finish hashing any remaining data if necessary, and perform and last steps. Then, return the hash.

Returns

The computed hash of all the data that had been added

Here is the caller graph for this function:

MurmurHash3_32_x32& bphash::detail::MurmurHash3_32_x32::operator= ( const MurmurHash3_32_x32 &  )

default

MurmurHash3_32_x32& bphash::detail::MurmurHash3_32_x32::operator= ( MurmurHash3_32_x32 &&  )

default

void bphash::detail::MurmurHash3_32_x32::reset ( void  )

virtual

Zero out the hash.

After this, you can start hashing something else again. May be called before or after finalize.

Here is the caller graph for this function:

void bphash::detail::MurmurHash3_32_x32::update ( void const *  data, size_t  nbytes  )

virtual

Add some data to the hash.

Parameters

[in]	data	The raw data to hash
[in]	nbytes	Number of bytes pointed to by data
