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.
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 |
public java.util.List getTransformations()
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.public OraExpressionTransform getExpressionTransform()
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.
