public class TransitionGraphOperator
extends Operator

This operator creates a transition graph from the given example set. The example set must have a specific structure with (at least) two columns where one column specifies the source of the transition and the second column specifies the target of the transition. Optionally, a third column can be specified in order to define the strength of the transition (this column can for example store the number of times this transition occurred after an aggregation).

The parameter "node_description" will be used for displaying information about the nodes if the information is made available via an example visualization operator. The string might contain macros pointing to attribute names.

Method Detail

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

createTransitionGraph

public TransitionGraph createTransitionGraph(ExampleSet exampleSet)
                                      throws UndefinedParameterError,
                                             UserError

Throws:

UndefinedParameterError

UserError

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
