compressChunk()

std::vector< uint8_t > o2::aod::native::test::compressChunk ( Algo  algo, std::span< const uint8_t >  in  )

inline

Definition at line 39 of file RootFraming.h.

makeBasket()

std::vector< uint8_t > o2::aod::native::test::makeBasket ( Algo  algo, std::span< const uint8_t >  values, int32_t  nevbuf, size_t  tailBytes = 0, size_t  chunkSize = 0xffffff  )

inline

A TBasket key as written on disk: key header, TBasket fields, then the payload holding values followed by a fake entry-offset tail.

Definition at line 114 of file RootFraming.h.

rootCompress()

std::vector< uint8_t > o2::aod::native::test::rootCompress ( Algo  algo, std::span< const uint8_t >  in, size_t  chunkSize = 0xffffff  )

inline

A ROOT compressed payload: chunks of at most chunkSize uncompressed bytes, each with its 9-byte header.
