	moves pointer to bytes and returns a pointer to data there

	Fills the storage (with undefined values) up to the nearest position aligned in bytes

Detailed Description

emFixStorage is aligned storage for fix local data, i.e.

data stored for EACH cell. It's based on std::vector of char with custom allocator. Aligment 64 is enough for AVX512 vectors.

Member Function Documentation

jump_aligned()

void * emFixStorage::jump_aligned ( std::ptrdiff_t &  dif, size_t  bytes  ) const

inline

moves dif shift to the nearest position aligned in bytes

Returns

a pointer to the found position

push_back()

template<typename FixType >

std::size_t emFixStorage::push_back ( const FixType &  fix )

inline

There are two ways to write into this structure, one is to write whole class into it.

Both functions return shift of the written data start.

write()

std::size_t emFixStorage::write ( const void *  newdata, std::size_t  size  )

inline

The other way writes specified size in bytes from pointer If the pointer is NULL, no actual write is performed, only reserves space It also returns shift of the written data begining.
