java.lang.Objectedu.udo.cs.yale.operator.Operator
edu.udo.cs.yale.operator.io.AttributeSetLoader
public class AttributeSetLoader
Loads an attribute set from a file and constructs the desired features. If keep_all is false, original attributes are deleted before the new ones are created. This also means that a feature selection is performed if only a subset of the original features was given in the file.

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.

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).
