Constructor Details

PEAFTheory

public PEAFTheory()

Default constructor; initializes an empty PEAFTheory

PEAFTheory

public PEAFTheory(Set<BArgument> noArguments)

Optional constructor; initializes an PEAFTheory with arguments

Parameters:

noArguments - the number of arguments

Method Details

addArgument

public BArgument addArgument(int identifier)

Add an argument with an integer identifier

Overrides:

addArgument in class AbstractEAFTheory<WeightedSetSupport>

Parameters:

identifier - the identifier of the argument

Returns:

EArgument object

addSupport

public void addSupport(Set<BArgument> froms,
 Set<BArgument> tos,
 double cp)

Add a support with sets for many to many mapping

Parameters:

froms - set with arguments that originate the support

tos - set with arguments that receive the support

cp - the result assigned to the support link (must be in range [0.0, 1.0])

addAttack

public void addAttack(BipolarEntity froms,
 BipolarEntity tos)

Add attack between arguments with indices

Overrides:

addAttack in class AbstractEAFTheory<WeightedSetSupport>

Parameters:

froms - the index of the EArgument that originates the attack

tos - the index of the EArgument that receieves the attack

getASCIITree

public String getASCIITree()

Returns an ascii tree for debug purposes. This is usually used in the unit tests.

Returns:

the ascii tree in string

printASCIITree

public void printASCIITree()

Helper function to print the ascii tree

isAcceptable

public boolean isAcceptable(BArgument argument,
 Collection<BArgument> ext)

Description copied from class: AbstractBipolarFramework

checks whether argument is acceptable wrt. ext

Specified by:

isAcceptable in class AbstractBipolarFramework

Parameters:

argument - some argument

ext - a set of arguments

Returns:

"true" if argument is acceptable wrt. ext

add

public boolean add(Support support)

Description copied from class: AbstractBipolarFramework

Adds the given support to this argumentation framework.

Specified by:

add in class AbstractBipolarFramework

Parameters:

support - a support

Returns:

"true" if the set of supports has been modified.

add

public boolean add(Attack attack)

Description copied from class: AbstractBipolarFramework

Adds the given attack to this argumentation framework

Specified by:

add in class AbstractBipolarFramework

Parameters:

attack - an attack

Returns:

"true" if the set of attacks has been modified.
