UDF

[Former Member]

Hi,

I want to use simple user defined function in xi to reverse a string .

I have written the java code :

public class StringRevChar {

public static void main(String[] argv) {

//+

String sh = "FCGDAEB";

System.out.println(sh + " -> " + new StringBuffer(sh).reverse());

//-

}

}

the code is working .

<b>But I dont know how to write this code in UDF portion of XI .</b>Pls help me .

Thanx & Regards,

somenath

Somenath,

Create simple UDF - Cache- Value ;

String sh ="FCGDAEB";

StringBuffer sb = new StringBuffer(sh);

sb.reverse();

return""sb.toString()"";

First double click on your target node which u wan2 assign the value,

Then double click on the source node

Drag your UDF in the Mapping editor area,

Then click and drag the arrow from source 2 UDF and UDF 2 target

Thanks

take a look into that link on how to create a UDF, and then try to implement the code that was provided in the above suggestion.

You don't need to use the Class name and Main methods in UDF. Just create a function with input parameter as the source string, and work on that string in order to get the output in reverse.

You can just use the logice which you have specified.

Hi

In the left hand side of Message Mapping Editor, there is an option User Defined.Use this and map it to the source and target.you will be successful in achieving your goal.

Hi Somenath,

The same code will work in XI also. Just few modification required.

1. take the your string as the input to the UDF and UDF type as value

2. Your input varible name is "sh"

3. Write the following logic

return( new StringBuffer(sh).reverse() );

This will work fine in XI. I hope you understand clearn.

Warm Regards,

Vijay

Please give your input tag as an argument to the UDF

Then in your udf do this

function(String arg, Container container)

{

String output = (new StringBuffer(arg).reverse()).toString();

return output;

}
