Constructor Summary

AbstractExampleSetEvaluator(OperatorDescription description)

Method Summary

void	doWork() Performs the actual work of the operator and must be implemented by subclasses.
abstract PerformanceVector	evaluate(ExampleSet exampleSet) Implements the evaluation.
boolean	shouldAutoConnect(OutputPort port) By default, all ports will be auto-connected by ExecutionUnit.autoWire(CompatibilityLevel, boolean, boolean).

Method Detail

evaluate

public abstract PerformanceVector evaluate(ExampleSet exampleSet)
                                    throws OperatorException

Implements the evaluation. Called by Operator.apply().

Throws:

OperatorException

doWork

public void doWork()
            throws OperatorException

Description copied from class: Operator

Performs the actual work of the operator and must be implemented by subclasses. Replaces the old method apply().

Overrides:

doWork in class Operator

Throws:

OperatorException

shouldAutoConnect

public boolean shouldAutoConnect(OutputPort port)

Description copied from class: Operator

By default, all ports will be auto-connected by ExecutionUnit.autoWire(CompatibilityLevel, boolean, boolean). Optional outputs were handled up to version 4.4 by parameters. From 5.0 on, optional outputs are computed iff the corresponding port is connected. For backward compatibility, operators can check if we should auto-connect a port by overriding this method (e.g. by checking a deprecated parameter). TODO: Remove in later versions

Overrides:

shouldAutoConnect in class Operator
