DECODE |
Searches a port for a value you specify. If the function finds the value, it
returns a result value, which you define. You can build an unlimited number

Below is an example of how to use the DECODE routine with a
tJava component. You need to add a tJava
component to a new Job, then enter the following code, which will search the value for
10, in the Code field on the
Basic settings view of the tJava
component.
TalendStringUtil<Integer,String> example = new TalendStringUtil<Integer,String>();
System.out.println(example.DECODE(10, "error", 5, "five", 10, "ten", 15, "fifteen", 20, "twenty"));Note that you need to create a new object of the TalendStringUtil type,
and better to use generic type to constrain the input data, then use the object to call the
DECODE routine.
Press F6 to run the Job. It will return ten, which
is the result of the value 10.
