Method Details

toPropositional

public Proposition toPropositional(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 FolAtom toFOL(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 Disjunction toFOL(Disjunction disjunction)

Translates the given propositional Disjunction to a FOL Disjunction

Parameters:

disjunction - a PL disjunction

Returns:

The FOL Disjunction

toPropositional

public Disjunction toPropositional(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

toPropositional

public ExclusiveDisjunction toPropositional(ExclusiveDisjunction xor)

Translates the given FOL Exclusive Disjunction to a propositional Exclusive Disjunction

Parameters:

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

Returns:

The propositional Exclusive Disjunction

toFOL

public Conjunction toFOL(Conjunction conjunction)

Translates the given propositional Conjunction to a FOL Conjunction

Parameters:

conjunction - a PL conjunction

Returns:

The FOL Conjunction

toPropositional

public Conjunction toPropositional(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 FolFormula toFOL(PlFormula propFormula)

Return FolFormula toFOL

Parameters:

propFormula - propFormula

Returns:

FolFormula toFOL

toPropositional

public PlFormula toPropositional(FolFormula folFormula)

Return PlFormula toPropositional

Parameters:

folFormula - folFormula

Returns:

PlFormula toPropositional
