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()

Description copied from interface: Formula
