Class SorterTransformation

All Implemented Interfaces:: Transform

public class SorterTransformation
extends Transformation
extends Transformation

The class SorterTransformation implements a Sorter Transformation. This class extends Transformation

Sorter Transformation is used to sort the input based on the sort port. There can be more than one sort port and the user has to specify the sort direction as ascending or descending for every sorter port. When more than one port is specified the PowerCentre sorts each port sequentially. The order of port is the order specified in the input set. In the TransformationProperties of sorter transformation the user can specify the Sorter Cache Size. For better preformance the Sorter Cache size should be less than the available ram. Case Senstive property determines whether PowerCentre considers case while Sorting.

For Further details see Transformation Guide.

The code snippet for the SorterTransformation is

            //create a Sorter Transformation using the constructor given below: 
           Mapping mapping = ...; // mapping to which the transform should be added
           InputSet inputSetObj = ...; // the InputSet object
           String[] sorterPort = ...; // the ports on which the sorting is to be done 
           boolean[] ascending = ...; // ascending or descending sort
           TransformationProperties props = ...; // properties        
           Vector vTransformField = ...; // collection of TransformField objects   
           SorterTransformation sorterTrans = new SorterTransformation( "SorterTrans", "SorterTrans", 
                                                   "This is sorter transformation", "SorterTrans", 
                                                   mapping, inputSetObj, sorterPort, ascending, 
                                                   props, vTransformField);
           
           //apply the transformation
           OutputSet outputSet = sorterTrans.apply();
           
           //get the first rowset as Sorter always returns a RowSet
           RowSet outRowSet = (RowSet)outputSet.getRowSets().get(0);
