  • Constructor Details

    • XXH32State

      public XXH32State(ByteBuffer container)
      Creates a XXH32State instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.

      public int total_len_32()
      total length hashed, modulo 2^32

    • large_len

      public int large_len()
      whether the hash is ≥ 16 (handles total_len_32 overflow)
