Hello,

User Defined Functions are Visible only inside the <b>Message Mapping,</b>Contains 1)Label 2)Argument Count 3)Description

Contains two types of UDF

1) Simple UDF :

<b>Process individual field input for each function call.Expects only string input.Returns string.</b>

2) Adv UDF :

<b>Process non-single string field.Works on the whole queue .Input field is passed as string array.Returned values are stored in ResultList.</b>

Hi

Here i will give you one of the example which uses Advanced UDF

<b>for e.g.</b>

abcd#efgh#ghji~klm

<b>should result in</b>

abcd

efgh

ghij

klm

each in a different line.

besides I have a queue of such strings

Ans:

StringTokenizer st = null;

String var="";

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

{

st= new StringTokenizer(a<i>,"#~");

while (st.hasMoreElements())

{

var =(String)st.nextElement();

result.addValue(var);

}

result.addContextChange();

}

Hi shakif,

There are 2 types of UDF - Simple and Advanced

- Simple UDFs uses Value, wherein we can manipulate only one value (input is one String). Therefore a single string is expected, as input and the output would also be a single string.

- Advanced UDFs uses Context or Queue, where you manipulate many values (input is an array of Strings).

Regards,

Ramana.
