      Modifier and Type Method Description
      abstract byte[] getAll()  
      byte[] getBlock​(int start, int length)  
      abstract byte[] getBlock​(long start, int length)  
      abstract java.lang.String getDescription()

      abstract java.io.InputStream getInputStream()  
      java.io.InputStream getInputStream​(long start)  
      abstract long getLength()
      This operation can be VERY expensive; for inputstream byte sources, the entire stream must be drained to determine its length.
