public abstract class AbstractDynamicArgumentList
extends AbstractArgument
implements Argument

Every Operator with dynamic number of arguments must inherit from this class. Its main function is to provide the standard implemention of AbstractArgument.equals(java.lang.Object), AbstractArgument.matches(com.meyling.principia.argument.Argument, com.meyling.principia.argument.PatternVariables) and AbstractArgument.hashCode().

IllegalArgumentException - if the argument was a nullpointer
Method Detail

add

public void add(Argument argument)
Adds an argument to end of dynamic list.
Parameters:
argument - argument to add
Throws:
IllegalArgumentException - if the given argument was a nullpointer

insert

public void insert(int position,
                   Argument argument)
Inserts an argument to spezified position.
Parameters:
position - position of argument to add
argument - argument to add
Throws:
IllegalArgumentException - if the given argument was a nullpointer or the position was not valid

replace

public void replace(int position,
                    Argument argument)
Replaces an argument at spezified position.
Parameters:
position - position of argument to replace
argument - replacement argument
Throws:
IllegalArgumentException - if the given argument was a nullpointer or the position was not valid

remove

public void remove(int i)
Deletes an argument of dynamic list.
Parameters:
i - position of argument to delete
Throws:
IllegalArgumentException - if the given position was not valid
