public class SplitChain
extends OperatorChain

An operator chain that split an ExampleSet into two disjunct parts and applies the first child operator on the first part and applies the second child on the second part and the result of the first child. The total result is the result of the second operator.

Method Detail

apply

public IOObject[] apply()
                 throws OperatorException

Description copied from class: OperatorChain

Applies all inner operators. The input to this operator becomes the input of the first inner operator. The latter's output is passed to the second inner operator and so on. Note to subclassers: If subclasses (for example wrappers) want to make use of this method remember to call exactly this method (super.apply()) and do not call super.apply(IOContainer) erroneously which will result in an infinite loop. Subclasses who override this method without invoking super.apply() should at least invoke the method OperatorChain.clearStepCounter().

Overrides:

apply in class OperatorChain

Returns:

the last inner operator's output or the input itself if the chain is empty.

Throws:

OperatorException

getInnerOperatorCondition

public InnerOperatorCondition getInnerOperatorCondition()

Description copied from class: OperatorChain

Must return a condition of the IO behaviour of all desired inner operators. If there are no "special" conditions and the chain works similar to a simple operator chain this method should at least return a SimpleChainInnerOperatorCondition. More than one condition should be combined with help of the class CombinedInnerOperatorCondition.

Specified by:

getInnerOperatorCondition in class OperatorChain

getInputDescription

public InputDescription getInputDescription(java.lang.Class cls)

Description copied from class: Operator

The default implementation returns an input description that consumes the input IOObject without a user parameter. Subclasses may override this method to allow other input handling behaviors.

Overrides:

getInputDescription in class Operator

getMaxNumberOfInnerOperators

public int getMaxNumberOfInnerOperators()

Returns the maximum number of innner operators.

Specified by:

getMaxNumberOfInnerOperators in class OperatorChain

getMinNumberOfInnerOperators

public int getMinNumberOfInnerOperators()

Returns the minimum number of innner operators.

Specified by:

getMinNumberOfInnerOperators in class OperatorChain

getInputClasses

public java.lang.Class[] getInputClasses()

Returns the the classes this operator provides as output.

Specified by:

getInputClasses in class Operator

getOutputClasses

public java.lang.Class[] getOutputClasses()

Returns the the classes this operator expects as input.

Specified by:

getOutputClasses in class Operator

getNumberOfSteps

public int getNumberOfSteps()

Description copied from class: OperatorChain

Returns the number of steps performed by this chain.

Specified by:

getNumberOfSteps in class OperatorChain

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.

Overrides:

getParameterTypes in class Operator
