Instance variables and user-defined methods.
Use any instance or static variable or user-defined method you declared in the Helper Code tab.
For example, an active Java transformation has two input ports, BASE_SALARY and BONUSES, with an integer datatype, and a single output port, TOTAL_COMP, with an integer datatype. You create a user-defined method in the Helper Code tab, myTXAdd, that adds two integers and returns the result. Use the following Java code in the On Input Row tab to assign the total values for the input ports to the output port and generate an output row:
TOTAL_COMP = myTXAdd (BASE_SALARY,BONUSES);
When the Java transformation receives an input row, it adds the values of the BASE_SALARY and BONUSES input ports, assigns the value to the TOTAL_COMP output port, and generates an output row.
