Constructor Detail

BTModalFormulaCompound

public BTModalFormulaCompound(ModalConnective mainConnective,
                              BTModalFormula left,
                              BTModalFormula right)

Build an instance of a compound formula with a binary main connective.

Parameters:

mainConnective - the connective of the formula.

left - the left sub-formula.

right - the right sub-formula.

BTModalFormulaCompound

public BTModalFormulaCompound(ModalConnective mainConnective,
                              BTModalFormula sub)

Build an instance of a compound formula with an unary main connective.

Parameters:

mainConnective - the connective of the formula.

sub - the main sub-formula.

Method Detail

shortName

public java.lang.String shortName()

Description copied from interface: _AbstractFormula

Returns the short name of the formula. It is only used to provide information on the proof-search. Typically the short is the main connective of the formula

Returns:

returns the short name of the formula

immediateSubformulas

public BTModalFormula[] immediateSubformulas()

Description copied from interface: _ModalFormula

The immediate subformulas of this formula.

Specified by:

immediateSubformulas in interface _ModalFormula

Specified by:

immediateSubformulas in class BTModalFormula

Returns:

the subformulas of this formula.

mainConnective

public ModalConnective mainConnective()

Description copied from interface: _ModalFormula

The main logical operator of this formula.

Returns:

the main connective of this formula.

isAtomic

public boolean isAtomic()

Description copied from interface: _ModalFormula

Returns true iff this formula is atomic.

Specified by:

isAtomic in interface _ModalFormula

Specified by:

isAtomic in class BTModalFormula

Returns:

true iff this formula is atomic.

isCompound

public boolean isCompound()

Description copied from interface: _ModalFormula

Returns true iff this formula is compound.

Specified by:

isCompound in interface _ModalFormula

Specified by:

isCompound in class BTModalFormula

Returns:

true iff this formula is compound.
