Class GridletPackets

Object
  GridletPackets

public class GridletPackets
extends Object

This class contains relevant information of a dropped Gridlet or File object. Since a gridlet or a file is broken into many packets according to the Maximum Transmission Unit (MTU), this class records the first packet ID, the last packet ID, and the Gridlet or File ID. This class is mainly used by the FnbInput and FnbOutput classes.

For example, a gridlet with id = 3 is made of 20 packets, e.g. from packet id 2 to 21. Then, this class stores the following information: the first packet number is 2, the last packet number is 21, the ID is 3, and isFile() returns false.

Since:

5.0
