peersim.cdsim
Class FullNextCycle

java.lang.Object
  peersim.cdsim.FullNextCycle

All Implemented Interfaces:

Control

Direct Known Subclasses:

NextCycle

public class FullNextCycle
extends java.lang.Object
implements Control

Control to run a cycle of the cycle driven simulation. This does not need to be explicitly configured (although you can do it for hacking purposes).

Parameter Summary

getpair
The type of the getPair function.

shuffle
Shuffle iteration order if set.

Field Summary

protected boolean	getpair_rand
protected Scheduler[]	protSchedules Holds the protocol schedulers of this simulation
protected RandPermutation	rperm The random permutation to use if config par "shuffle" is set.
protected boolean	shuffle

Constructor Summary

FullNextCycle(java.lang.String prefix)
Reads config parameters and Schedulers.

Method Summary

boolean

execute() Execute all the CDProtocols on all nodes that are up.

Parameter Detail

getpair

The type of the getPair function. This parameter is of historic interest and was needed in a publication we wrote. You don't need to care about this. But if you wanna know: if set to "rand", then in a cycle the simulator does not simply iterate through the nodes, but instead picks a random one N times, where N is the network size.

shuffle

Shuffle iteration order if set. Not set by default. If set, then nodes are iterated in a random order. However, in the network the nodes actually stay in the order they originally were. The price for leaving the network untouched is memory: we need to store the permutation we use to iterate the network.

Field Detail

getpair_rand

protected final boolean getpair_rand

shuffle

protected final boolean shuffle

protSchedules

protected Scheduler[] protSchedules

Holds the protocol schedulers of this simulation

rperm

protected RandPermutation rperm

The random permutation to use if config par "shuffle" is set.

Constructor Detail

FullNextCycle

public FullNextCycle(java.lang.String prefix)

Reads config parameters and Schedulers.

Method Detail

execute

public boolean execute()

Execute all the CDProtocols on all nodes that are up. If the node goes down as a result of the execution of a protocol, then the rest of the protocols on that node are not executed and we move on to the next node. It sets the CDState appropriately.

Specified by:

execute in interface Control

Returns:

always false
