BasicSubjectVariablePatternVariable

public BasicSubjectVariablePatternVariable(Argument[] arguments)
                                    throws ArgumentException
Constructs a pattern variable.
Parameters:
arguments - first argument is number of this pattern variable
Throws:
ArgumentException - if there is not exactly one argument that is an instance of Counter

BasicSubjectVariablePatternVariable

public BasicSubjectVariablePatternVariable(int number)
                                    throws ArgumentException
Constructs a pattern variable.
Parameters:
number - of this pattern variable
Throws:
ArgumentException - if there couldn't be made a Counter out of number
Method Detail

getPatternVariables

public final PatternVariables getPatternVariables()
Description copied from interface: Argument
Get all pattern variables that occur in this argument.
Specified by:
getPatternVariables in interface Argument

getPatternVariables in class AbstractArgument
Following copied from interface: com.meyling.principia.argument.Argument
Returns:
all pattern variables

isMatching

public boolean isMatching(Argument argument)
Is the argument matching the pattern variable? Here true is returned if argument is an SubjectVariable.
Overrides:
isMatching in class PatternVariable
Parameters:
argument - argument to match pattern variable
Returns:
true

create

public final Argument create(Argument[] arguments)
                      throws ArgumentException
Description copied from interface: Argument

Specified by:
create in interface Argument
Overrides:
create in class PatternVariable
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
