Constructor Detail

Quantifier

public Quantifier(Argument[] arguments)
           throws ArgumentException
Constructs a logical quantifier.
Parameters:
arguments - subject variable and formula to operate on
Throws:
ArgumentException - if there are not exactly two arguments ore the first argument is not an instance of SubjectVariableMarker or the second argument is not an instance of Formula or the subject variable is not free in the formula
Method Detail

getPartFormulaSize

public final int getPartFormulaSize()

Specified by:
getPartFormulaSize in interface Formula
Overrides:
getPartFormulaSize in class AbstractFormula
Returns:
always 1

getPartFormula

public final Formula getPartFormula(int i)
Description copied from interface: Formula
