public interface IODescription

This interface describes the (expected) input and (guaranteed) output classes of operators.

Author:

Ingo Mierswa

Method Summary

java.lang.Class<?>[]	getInputClasses() Returns the classes that are expected as input.
java.lang.Class<?>[]	getOutputClasses(java.lang.Class<?>[] input, Operator operator) Returns the output classes dependent on the outputBehaviour PASS_UNUSED_INPUT_TO_OUTPUT:output classes are the classes used in the constructor plus those classes in input[] that were not consumed.

Method Detail

getInputClasses

java.lang.Class<?>[] getInputClasses()

Returns the classes that are expected as input.

getOutputClasses

java.lang.Class<?>[] getOutputClasses(java.lang.Class<?>[] input,
                                      Operator operator)
                                      throws IllegalInputException

Returns the output classes dependent on the outputBehaviour

• PASS_UNUSED_INPUT_TO_OUTPUT:output classes are the classes used in the constructor plus those classes in input[] that were not consumed. Classes are supposed to be consumed by the operator if they find a matching class in the input classes used in the constructor (which can be a superclass or interface)
• DELETE_UNUSED_INPUT:output classes are exactly those classes used in the constructor.

In either case the output classes precede the unused input classes. Their order is conserved.

Throws:

IllegalInputException
