Interface OraTransformationSequence

All Superinterfaces:
javax.datamining.MiningObject

public interface OraTransformationSequence
extends javax.datamining.MiningObject

OraTransformationSequence represents a sequence of transformations. It is a new named object introduced in 11.1, so the user can reuse the defined transformations easily. First step is to create individual transformations that are to be performed on a dataset using OraTransformationFactory create methods. Collect them as an ordered list and give them as an input to OraTransformationFactory.createTransformationSequence method.

Since:
OJDM 11.1.0

Method Summary
 OraExpressionTransform getExpressionTransform()
          Returns OraExpressionTransform that is used to created the transformation sequence object.
 java.util.List getTransformations()
          Returns ordered list of transformations in this transformation sequence object.

Method Detail

getTransformations

public java.util.List getTransformations()
Returns ordered list of transformations in this transformation sequence object. List object contains the OraTransformation object, user can discover the type of transformation using instanceOf operation. Returns null when the transformation sequence is created as a stand-alone expression transform.
Returns:

getExpressionTransform

public OraExpressionTransform getExpressionTransform()
Returns OraExpressionTransform that is used to created the transformation sequence object. Method OraTranformationFactory.createTransformationSequence( String inputDataURI, OraExpressionTransform expressionTransform, String outputDataURI) is used to create transformation sequence with expression transform.
Returns:
