de.rwth.i2.attestor.phases.modelChecking.modelChecker.Assertion

public class Assertion
extends Object

This class implements the states of the tableau method proof structure. Each state consists of a program state and a list of (sub)formulae, which together form an assertion, that has to be discharged.

Constructor Detail

Assertion

public Assertion(int progState,
                 Assertion parent)

Assertion

public Assertion(int progState,
                 Assertion parent,
                 de.rwth.i2.attestor.LTLFormula formula)

Assertion

public Assertion(Assertion assertion)

This constructor returns a new assertion as a copy of the provided one. Note that the new assertion receives a shallow copy of the formulae list.

Parameters:

assertion, - the assertion to be copied

Assertion

public Assertion(int progState,
                 Assertion parent,
                 boolean isContainedInTrace)

This constructor returns a new assertion as a copy of the provided one. Note that the new assertion receives a shallow copy of the formulae list.

Method Detail

getProgramState

public int getProgramState()

isTrue

public boolean isTrue()

getFirstFormula

public de.rwth.i2.attestor.generated.node.Node getFirstFormula()

removeFormula

public void removeFormula(de.rwth.i2.attestor.generated.node.Node formula)

addFormula

public void addFormula(de.rwth.i2.attestor.generated.node.Node formula)

This method adds a formula to the list of formulae in case it is not already contained (otherwise no action is performed). Note that add respects the insertion order forced by the tableau method, i.e. next formulae are inserted at the back of the list, while all remaining formulae are inserted at its beginning.

Parameters:

formula, - the formula to be added

setTrue

public void setTrue()

removeFirstFormula

public void removeFirstFormula(de.rwth.i2.attestor.generated.node.Node node)

stateIDAndFormulaeToString

public String stateIDAndFormulaeToString()

getParent

public Assertion getParent()
