temporalStep

public Formula temporalStep(BitSet valuation)

Description copied from class: Formula

Do a single temporal step. This means that one layer of X-operators is removed and literals are replaced by their valuations.

Specified by:

temporalStep in class Formula

substitute

public Formula substitute(Function<? super Formula.TemporalOperator,? extends Formula> substitution)

Specified by:

substitute in class Formula

accept

public int accept(IntVisitor v)

Specified by:

accept in class Formula

accept

public <R> R accept(Visitor<R> v)

Specified by:

accept in class Formula

accept

public <A,B> A accept(BinaryVisitor<B,A> v,
                            B parameter)

Specified by:

accept in class Formula

getAtom

public int getAtom()

isNegated

public boolean isNegated()

isPureEventual

public boolean isPureEventual()

Specified by:

isPureEventual in class Formula

isPureUniversal

public boolean isPureUniversal()

Specified by:

isPureUniversal in class Formula

nnf

public Formula nnf()

Specified by:

nnf in class Formula

not

public Literal not()

Description copied from class: Formula

Syntactically negate this formula.

If this formula is in NNF, the returned negation will also be in NNF.

Specified by:

not in class Formula

Returns:

the negation of this formula.

toString

public String toString()

Overrides:

toString in class Object

compareValue

protected int compareValue(Formula o)

Overrides:

compareValue in class Formula

equalsValue

protected boolean equalsValue(Formula o)

Overrides:

equalsValue in class Formula
