public abstract class AbstractWriter<T extends IOObject>
extends Operator

Superclass of all operators that take a single object as input, save it to disk and return the same object as output. This class is mainly a tribute to the e-LICO DMO. It defines precondition and a pass through rule for its output port.

Constructor Detail

AbstractWriter

public AbstractWriter(OperatorDescription description,
                      java.lang.Class<T> savedClass)
Method Detail

write

public abstract T write(T ioobject)
                                  throws OperatorException
Creates (or reads) the ExampleSet that will be returned by Operator.apply().

Returns:
the written IOObject itself
Throws:
OperatorException

doWork

public final 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

supportsEncoding

protected boolean supportsEncoding()

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. ATTENTION! This will create new parameterTypes. For calling already existing parameter types use getParameters().getParameterTypes();

Specified by:
getParameterTypes in interface ParameterHandler
Overrides:
getParameterTypes in class Operator
