    • get

      public ByteChunk get() throws AlreadyClosedException, ScxIOException
      Description copied from interface: ByteSupplier

      获取下一个数据块

      • 必须是推进式的阻塞拉取
      • 如果当前已经读取到有效数据 -> 返回 ByteChunk(len > 0)
      • 如果暂时无法输出数据, 但 I/O 状态确实推进了 -> 返回 EMPTY_BYTE_CHUNK
      • 如果 EOF 且不会再产生数据 -> 返回 null
      • 不允许无状态的空循环: 供应者不得无意义地连续返回 EMPTY_BYTE_CHUNK
      • 连续多次调用 get() 必须使底层数据源或解码状态单调推进
