Constructor & Destructor Documentation

murmur3() [1/2]

template<typename THash >

etl::murmur3< THash >::murmur3 ( value_type  seed_ = 0 )

inline

Default constructor.

Parameters

seed	The seed value. Default = 0.

murmur3() [2/2]

template<typename THash >

template<typename TIterator >

etl::murmur3< THash >::murmur3 ( TIterator  begin, const TIterator  end, value_type  seed_ = 0  )

inline

Constructor from range.

Parameters

begin	Start of the range.
end	End of the range.
seed	The seed value. Default = 0.

Member Function Documentation

add() [1/2]

template<typename THash >

template<typename TIterator >

void etl::murmur3< THash >::add ( TIterator  begin, const TIterator  end  )

inline

Adds a range.

Parameters

begin
end

add() [2/2]

template<typename THash >

void etl::murmur3< THash >::add ( uint8_t  value_ )

inline

Adds a uint8_t value. If the hash has already been finalised then a 'hash_finalised' error will be emitted.

Parameters

value

The char to add to the hash.
