Helper code

Helper code

Declare user-defined variables and methods for the Java transformation in the Helper Code section.
The Helper Code section defines the following variables that are used by the Java code in the On Input Row section:
Variable
Description
empMap
Map object that stores the identification number and employee name from the source.
lock
Lock object used to synchronize the access to empMap across partitions.
generateRow
Boolean variable used to determine whether an output row should be generated for the current input row.
isRoot
Boolean variable used to determine whether an employee is at the top of the company organizational chart (root).
Enter the following code in the Helper Code section:
// Static Map object to store the ID and name relationship of an employee. // If a session uses multiple partitions, empMap is shared across all partitions. private static Map <Integer, String> empMap = new HashMap <Integer, String> (); // Static lock object to synchronize the access to empMap across partitions. private static Object lock = new Object(); // Boolean to track whether to generate an output row based on validity of the // input data. private boolean generateRow; // Boolean to track whether the employee is root. private boolean isRoot;
Data Integration
adds the import statements to the Java code for the transformation.
