Class ArgumentationEnvironment

java.lang.Object

net.sf.tweety.agents.dialogues.ArgumentationEnvironment

All Implemented Interfaces:

Environment, Perceivable

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

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

Constructor Detail

ArgumentationEnvironment

public ArgumentationEnvironment(DungTheory universalTheory)

Creates a new grounded environment.

Parameters:

universalTheory - the universal Dung theory used for argumentation.

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

Parameters:

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:

a set of percepts perceivable for the given agent.

getDialogueTrace

public DialogueTrace<Argument,Extension> getDialogueTrace()

Returns the current dialogue trace.

Returns:

the current dialogue trace.

reset

public boolean reset()

Description copied from interface: Environment

Resets the environment, i.e. brings it to its initialization state.

Specified by:

reset in interface Environment

Returns:

"true" iff reset was successful.

getPerceivedDungTheory

public DungTheory getPerceivedDungTheory(Extension arguments)

Returns the view of the universal Dung theory restricted to the given set of arguments.

Parameters:

arguments - a set of arguments.

Returns:

the projection of the universal theory.
