  - ### Method Detail

    - #### read

          public int read()
                   throws java.io.IOException

      Specified by:
        `read` in class `java.io.InputStream`
      Throws:
        `java.io.IOException`

    - #### readFully

          public void readFully(byte[] buffer,
                                int offset,
                                int count)
                         throws java.io.IOException

      Description copied from class: `AbstractDataInput`
      Read bytes from this file into `buffer` starting at offset `offset`. This method blocks until `count` number of bytes have been read.
      Specified by:
        `readFully` in interface `java.io.DataInput`
      Overrides:
        `readFully` in class `AbstractDataInput`
      Parameters:
        `buffer` - the buffer to read bytes into.
        `offset` - the initial position in `buffer` to store the bytes read from this file.
        `count` - the maximum number of bytes to store in `buffer`.
      Throws:
        `java.io.EOFException` - if the end of this file is detected.
        `java.io.IOException` - if this file is closed or another I/O error occurs.

    - #### seek

          public void seek(long pos)

      Specified by:
        `seek` in class `AbstractDataInput`

    - #### getPosition

          public long getPosition()

      Specified by:
        `getPosition` in class `AbstractDataInput`

    - #### getPositionLimit

          public long getPositionLimit()

      Specified by:
        `getPositionLimit` in class `AbstractDataInput`

    - #### length

          protected long length()

    - #### close

          public void close()

      Specified by:
        `close` in interface `java.io.Closeable`
      Specified by:
        `close` in interface `java.lang.AutoCloseable`
      Overrides:
        `close` in class `java.io.InputStream`
