Method Detail

toPropositional

public net.sf.tweety.logics.pl.syntax.Proposition toPropositional(net.sf.tweety.logics.fol.syntax.FolAtom atom)

Translates the given FOL-Atom into a Proposition

Parameters:

atom - FOL-Atom, if the given Atom has arguments an exception is thrown.

Returns:

Propositional form of the given Atom

toFOL

public net.sf.tweety.logics.fol.syntax.FolAtom toFOL(net.sf.tweety.logics.pl.syntax.Proposition proposition)

Translates the given proposition into a FOL-Atom

Parameters:

proposition - The Proposition

Returns:

A FOL-Atom representing the given Proposition in first order logic.

toFOL

public net.sf.tweety.logics.fol.syntax.Disjunction toFOL(net.sf.tweety.logics.pl.syntax.Disjunction disjunction)

Translates the given propositional Disjunction to a FOL Disjunction

Parameters:

disjunction - a PL disjunction

Returns:

The FOL Disjunction

toPropositional

public net.sf.tweety.logics.pl.syntax.Disjunction toPropositional(net.sf.tweety.logics.fol.syntax.Disjunction disjunction)

Translates the given FOL Disjunction to a propositional Disjunction

Parameters:

disjunction - The FOL-Disjunction, if it contains formulas which are not expressible in propositional logic an exception is thrown.

Returns:

The propositional Disjunction

toFOL

public net.sf.tweety.logics.fol.syntax.Conjunction toFOL(net.sf.tweety.logics.pl.syntax.Conjunction conjunction)

Translates the given propositional Conjunction to a FOL Conjunction

Parameters:

conjunction - a PL conjunction

Returns:

The FOL Conjunction

toPropositional

public net.sf.tweety.logics.pl.syntax.Conjunction toPropositional(net.sf.tweety.logics.fol.syntax.Conjunction conjunction)

Translates the given FOL Conjunction to a propositional Conjunction

Parameters:

conjunction - The FOL-Conjunction, if it contains formulas which are not expressible in propositional logic an exception is thrown.

Returns:

The propositional Conjunction

toFOL

public net.sf.tweety.logics.fol.syntax.FolFormula toFOL(net.sf.tweety.logics.pl.syntax.PlFormula propFormula)

toPropositional

public net.sf.tweety.logics.pl.syntax.PlFormula toPropositional(net.sf.tweety.logics.fol.syntax.FolFormula folFormula)
