Method Detail

write

public ExampleSet write(ExampleSet exampleSet)
                 throws OperatorException

Description copied from class: AbstractWriter

Creates (or reads) the ExampleSet that will be returned by AbstractWriter.apply().

Specified by:

write in class AbstractWriter<ExampleSet>

Returns:

the written IOObject itself

Throws:

OperatorException

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.
