Class RandomAnt

java.lang.Object
  |
  +--ants.random.RandomAnt

All Implemented Interfaces:

Ant, Serializable

public class RandomAnt

extends Object

implements Ant, Serializable

This class contains the implementation of a simple ant which performs a random walk through the network. Ants move forward until they reach the searched resource; then, they move backward along the incoming path. When they reach the requestor nest, they copy the resource locally.

RandomAnt

public RandomAnt(RequestId rid,
                 String query)

Instantiate a new RandomAnt by setting the query to be satisfied and the hash value to be searched.

Method Detail

getSpecies

public String getSpecies()

Returns the identifier of the "species" of this ant. Different ant species may have access to different pheromone information in nests.

Specified by:

getSpecies in interface Ant

init

public void init(AntView view)

Description copied from interface: Ant

This method is called on ants at the initialization time. The view delivered to ants is not fully functional; for example, ants cannot move to other nests or create new ants during the execution of init(). FIXME Implement the control in LocalAntView.

Specified by:

init in interface Ant

run

public void run(AntView view)

This method encapsulate the computation performed by the ant.

Specified by:

run in interface Ant

Parameters:

view - reference to the AntView object which constitutes the controlled environment of the ant

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

IOException

readExternal

public void readExternal(ObjectInput in)
