edu.udo.cs.yale.operator.MacroDefinitionOperator
public class MacroDefinitionOperator
(Re-)Define macros for the current experiment. Macros will be replaced in the value strings of parameters by the macro values defined in the parameter list of this operator. Please note that this features is basically only supported for string type parameter values (strings or files).
In the parameter list you have to define the macro name (without the enclosing brackets) and the macro value. The defined macro can then be used in all succeeding operators as parameter value for string type parameters. A macro must then be enclosed by "%{" and "}".
There are several predefined macros:
In addition to those the user might define arbitrary other macros which will be replaced by arbitrary string during the experiment run.

OperatorException
public java.lang.Class[] getInputClasses()
Operator
Operator.getOutputClasses()
and
Operator.apply()
if this is necessary. This default behavior can be
changed by overriding Operator.getInputDescription(Class)
. Subclasses
which implement this method should not make use of parameters since this
method is invoked by getParameterTypes(). Therefore, parameters are not
fully available at this point of time and this might lead to exceptions.
Please use InputDescriptions instead.

Operator

and can be changed by
overwriting this method. Objects which are not consumed must not be
defined as additional output in this method. May be null or an empy array
(no additional output is produced).
