User Defined Function

[Former Member]

Hi all,

I need to create a message mapping where two output messages are involved. I need to map the input to one of the output messages based on the value of one of the parameters. How to create a user defind functionfor the same.

Input structure: name , age

Output 1 : name, age

Output 2 : name, age, status

Here status has to be "Elgible" if age is above 18 else "not eligible".

Can any one please provide me with the details like what kind of UDF it should be, Simple or Advanced ? How many input parameters? and the jave code to be written in UDF? also how to map this to output ?

Help will be appriciated.

Thanks and best regards,

Kulwant

There is no need for UDF. U can directly use standard function "If"

and map the constants to it.

Kulwant,

If the target is two messages, then follow the logic.

For Message 1

Name ---> Name

Age -

---

> Age

For Message 2

Name -

---

>Name

Age------>Age

Age & Constant(18) -

---

>greater------>IF Then Else -

---

>Eligibility

Then -

---

> Constant(Eligible)

Else -

---

>Constant(Not Eligible)

Hi Kulwant,

put this code in your udf for geting the status depending upon the age.

Step 1: Create a simple udf named getStatus with two arguments : name and age

Step 2: After creating paste the below code in the udf editor.

public String getStatus(String name,String age,Container container){

if(Integer.parseInt(age)>18)

return "Eligible";

else

return "Not Eligible";

}

Step 3: Save & Close the udf editor and test your mapping.

Please reward points if helpful.

Hi

u can use the foloowin udf.

the udf is having three inputs.

a----->age

b----->name

c----->status

for(int i=0;i<a.lrength;i++)

{

if(a<i>.equals("18"))

{

result.addValue(a);

result.addValue(b);

}

else

{

result.addValue(a);

result.addValue(b);

result.addVAlue(c);

}

}

if u still face the problem please reply me back.

Thanks

Kulwant,

You have one source message and two target messages is it?

hello raj,

yes. But only one of them needs to be mapped based on the value of age.

Hi,
