Class LotteryArgumentationEnvironment

java.lang.Object

net.sf.tweety.agents.dialogues.LotteryArgumentationEnvironment

All Implemented Interfaces:

Environment, Perceivable

public class LotteryArgumentationEnvironment
extends java.lang.Object
implements Environment, Perceivable

This class models the environment for agents in argumentation games with lotteries. It consists of the universal Dung theory used for argumentation (but not completely revealed to all agents) and the current trace of disclosed Dung theories.

Method Detail

execute

public java.util.Set<Perceivable> execute(Executable action)

Description copied from interface: Environment

Executes the given action and returns the resulting percepts.

Specified by:

execute in interface Environment

Parameters:

action - an executable

Returns:

a set of percepts.

execute

public java.util.Set<Perceivable> execute(java.util.Collection<? extends Executable> actions)

Description copied from interface: Environment

Executes the given actions simultaneously and returns the resulting percepts.

Specified by:

execute in interface Environment

actions - a collection of executables.

Returns:

a set of percepts.

getPercepts

public java.util.Set<Perceivable> getPercepts(Agent agent)

Description copied from interface: Environment

Retrieves the current percepts for the given agent.

Specified by:

getPercepts in interface Environment

Parameters:

agent - an agent.

Returns the current dialogue trace.

Returns:

the current dialogue trace.

reset

public boolean reset()

Description copied from interface: Environment
