Constructor Detail

PredicateVariable

public PredicateVariable(Argument[] arguments)
                  throws ArgumentException
Constructs a predicate variable with an argument list.
Parameters:
arguments - identity number of predicate variable and a list of arguments that are all an instance of SubjectVariableMarker
Throws:
ArgumentException - if there are not exactly two arguments or the first argument is no instance of CounterMarker or the second argument is no instance of RegularArgumentList or the entries of the second argument are no instances of SubjectVariableMarker
Method Detail

getNumber

public int getNumber()

Description copied from interface: Formula
Get all free subject variables.
Specified by:
getFreeSubjectVariables in interface Formula
Overrides:
getFreeSubjectVariables in class AbstractFormula
Following copied from interface: com.meyling.principia.logic.basic.Formula
Returns:
all free subject variables

getBoundSubjectVariables

public final SubjectVariables getBoundSubjectVariables()
Description copied from interface: Formula

Specified by:
getSubjectVariables in interface Formula
Overrides:
getSubjectVariables in class AbstractFormula
Following copied from interface: com.meyling.principia.logic.basic.Formula
Returns:
all subject variables

create

public final Argument create(Argument[] arguments)
                      throws ArgumentException
Description copied from interface: Argument
Create a new Argument with given arguments.
Specified by:
create in interface Argument
Overrides:
create in class AbstractArgumentList
Following copied from interface: com.meyling.principia.argument.Argument
Parameters:
arguments - with these arguments the operator should be created
Returns:
new constructed Argument
Throws:
ArgumentException - if creation failed

toString

public final String toString()
Description copied from interface: Argument
