All Implemented Interfaces:: Transform

public class CustomTransformation
extends Transformation
extends Transformation

This class implements the Custom Transformation for Active and Passive type. It extends the base Transformation to provide this functionality.

Each Custom transformation specifies a module and a procedure name. You can create a Custom transformation based on an existing shared library or DLL containing the procedure, or you can create a Custom transformation as the basis for creating the procedure. When you create a Custom transformation to use with an existing shared library or DLL, make sure you define the correct module and procedure name

A Active Custom transformation has both input and output groups. It also can have input ports, output ports, and input/output ports. A Passive Custom transformation has only one input and one output group.

The Custom transformation is created using set of GroupSet. The GroupSet has InputSet (input/output ports) and OutputField (output ports) used in Custom Transformation. The apply method validates type of custom transformation. It throws InvalidTransformationException if Passive custom transformation has more than one input and output GroupSet.

The snippet code shows how to create the Custom Transformation,

         //Create a TransformationContext object using set of GroupSet
         TransformationContext tc = new TransformationContext(vgrpSet); 
         
         //Create a Active CustomTransformation using a  (group ports) 
         //For Passive Custom Transformation use Transformation type as TransformationConstants.PASSIVE_CUSTOM 
         customTransform = tc.createTransform(TransformationConstants.ACTIVE_CUSTOM, TransformName); 
         
         //Apply the Custom Transformation
         customTransform.apply();
         
         OR
         
          //you can use helper class
         helper.custom(vGroupSet, TransformationConstants.ACTIVE_CUSTOM , "Custom_Trnasformation_Name" )
        
        apply method returns OutputSet object
