Class RulesExecutorMeta

java.lang.Object

org.pentaho.di.trans.step.BaseStepMeta

org.pentaho.di.trans.steps.rules.RulesExecutorMeta

All Implemented Interfaces:

Cloneable, StepAttributesInterface, StepMetaInterface

public class RulesExecutorMeta
extends BaseStepMeta
implements StepMetaInterface

This Transformation Step allows a user to execute a rule set against an individual rule or a collection of rules. Additional columns can be added to the output from the rules and these (of course) can be used for routing if desired.

getStep

public StepInterface getStep(StepMeta stepMeta,
                    StepDataInterface stepDataInterface,
                    int copyNr,
                    TransMeta transMeta,

Description copied from interface: StepMetaInterface

Get the executing step, needed by Trans to launch a step.

Specified by:

getStep in interface StepMetaInterface

Parameters:

stepMeta - The step info

stepDataInterface - the step data interface linked to this step. Here the step can store temporary data, database connections, etc.
