abstract fun read(offset: Long!, nofBytes: Long!): Future<ByteBuffer!>!
Read a chunk of the buffer. Reading past end is safe, and produce no data as a result.
offset - Long!: Where to start reading, in bytes. First byte is at offset 0.
nofBytes - Long!: The amount of bytes to try reading.
Return
Future<ByteBuffer!>!: the data read, of size equal to min(nofBytes, size - offset).
