  - ### Method Detail

    - #### fromConf

          public static InputStream fromConf(Map<String,Object> conf)

      Create an output stream from a config.

      Parameters:
        `conf` - the config to read from.
      Returns:
        the read OutputStream.

    - #### toConf

          public Map<String,Object> toConf()

      Convert this to a conf.

      Returns:
        the conf.

    - #### gsid

          public GlobalStreamId gsid()

      Get the global stream id for this input stream.

      Returns:
        the GlobalStreamId for this input stream.

    - #### remap

                                   Map<GlobalStreamId,GlobalStreamId> remappedStreams)

      Remap the names of components.

      Parameters:
        `remappedComponents` - old name to new name of components.
        `remappedStreams` - old ID to new ID of streams.
      Returns:
        a modified version of this with names remapped.

    - #### replaceShuffleWithLocalOrShuffle

          public InputStream replaceShuffleWithLocalOrShuffle()
