jsim.process
Class Signal

java.lang.Object
  jsim.process.DynamicNode
      jsim.process.Signal

All Implemented Interfaces:

java.lang.Runnable

public class Signal
extends DynamicNode
implements java.lang.Runnable

The Signal class allows resource capacity to be altered via signals. A Signal object can affect the behavior of servers, by alternatively, increasing or decreasing the number of tokens (service units).

Constructor Detail

Signal

public Signal(Prop props,
              Server serverList,
              Transport[] outgoing)

Constructs a Signal to control the operation of Servers. This constructor has sufficient information to draw the node and its outgoing edges.

Parameters:

property - properties of node

serverList - list of affected servers

outgoing - outgoing transports

Signal

public Signal(int id,
              Prop props,
              Server serverList,
              Transport[] outgoing,
              AnimationQueue sharedQueue)

Constructs a Signal to control the operation of Servers. This constructor has sufficient information to draw the node and its outgoing edges.

Parameters:

property - properties of node

serverList - list of affected servers

outgoing - outgoing transports

Method Detail

start

public void start()

This method starts the Signal thread.

stop

public void stop()

This method stops the Signal thread.

getStopped

public boolean getStopped()

This method returns the status of the Signal.

Returns:

boolean whether this signal is stopped

run

public void run()

The run method of Signal. This determines the lifetime of the Signal and the signaling cycles.

Specified by:

run in interface java.lang.Runnable
