      The relative offset into the shared memory page where the bytes for this buffer starts

    • length

      public long length()
      The absolute length (in bytes) of the memory buffer. The memory is found from offset (inclusive) to offset + length (non-inclusive). When building messages using the encapsulated IPC message, padding bytes may be written after a buffer, but such padding bytes do not need to be accounted for in the size here.
