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 of
searches within a |

Below is an example of how to use the DECODE function 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.
