UDF help -break statement

[Former Member]

Hi all,

I have a problem with my UDF. <i>A break statement doesnt break out of the for loop. </i>Please go thru the follwing and offer your helping hand.

<b>The Issue:</b>

In need to <i>check the value of a "child" element for each occurrence of the parent node </i>and if the condition is true then <i>map the value of "1" to the target element </i>with the same name and a same parent.

<b>Source Structure:</b>

ParentNode1 <1..1>

...Child Node1 <1.unbounded>

.... Flag_Source <1.1>

<b> Target Structure</b>

ParentNode1 <1..1>

....Child Node <1. unbounded>

Flag_Target <1.1.> Mapping

<b>GUI Mapping: </b>

(Flag Source) -

---

[UDF]>>>>>>FlagTarget

^-

(ChildNode1) -

---

^

<b>Condition:</b>

for each child node1

If ParentNode1>ChildNode1>FlagSource = 1

then Flag-Target = 1

<b>Global Integer Element flag</b>

int flag;

<b>UDF:</b>

<i>Info:</i> Type is Context;

Takes 2 Arguments

1. Flag_Source- <i>Context Set to ParentNode</i>

2.ChildNode1

AbstractTrace trace = container.getTrace();

for ( int j = 1; j < ChildNode1.length; j++)<i>

{

if ( Flag_Source[j].equals(" 1")){

trace.addInfo("retrieved the value"+Flag_Source[j]);

flag = 1;

break; <b>// the for loop does not terminate here</b>

}else

{

flag= 0;

}

}

if ( flag == 1) {

result.addValue("1");

}

else

{

result.addValue("0");

}

<b>Testing</b>

Also when i test the mapping , I get the following error

<b>

"Cannot produce target element..

Check xml instance is valid for source xsd and target-field mapping fulfills..."</b>

Please help me with your suggestions

Thanks

regards

Hi All

I have gone through both the solutions. Mudit has provided a right one but I would suggest that it ll affect the performance as the loop will run up till the end although the value "1" is encountered in between.

Follow this logic. i think it helps.

for ( int j = 1; j < ChildNode1.length; j++)

{

if ( Flag_Source[j].equals(" 1")){

trace.addInfo("retrieved the value"+Flag_Source[j]);

result.addValue("1");

exit(0);

}else

{

result.addValue("0");

}

}

Thanks

Hi Amit,

Your logic is right.But i do not understand about "exit(0)".When i implement exit(0) my system gives

<b>cannot resolve symbol symbol : method exit (int) location: class com.sap.xi.tf._XX_XXXX_ exit(0); ^ 1 error</b>

Do you explain this?

We have a blog that gives us concept about System.exit(0)

Hi all,

I have successfully mapped the source to the target.

I was working simultaneously on the issue. I just saw your responses and i appreciate all of your feedback.

Mudit,

As per your soultion, I would not achieve the desire result because I need to read the value of "flag_source" for every instance of childnode1 and i can only achieve this by havin

ffor(int i=0; i< childnode1.length;i++) and not flagnode.length as you have suggested.

Samarajit,

Nice observation about the blanks space:) but you know what I spent a lot of time just to figure that there was a blank comming up before 1:)

Amit,

Your solution closely matches up my "Working" function though I had to fix some context related issues. I used "SplitByValue"for that .

Thank you all again for your inputs

Regards

Hi Krish,

In your code i found a blank space...remove that and run UDF again...Thats why can not entered the loop.

>> if ( Flag_Source[j].equals(" 1"))

if ( Flag_Source[j].equals("1"))

>>for ( int j = 1; j < ChildNode1.length; j++)

why you staring with j=1?It should be j=0

for ( int j = 0; j < ChildNode1.length; j++)

Cheers!

Hi;

You mean to say that if under any of your child nodes if flag has value 1 then you have to map 1 to the target flag node.

One question is target flag node has a single occurance or its under child node.

Use this UDF

Type context

Input flagnode(contxt set to parent)

int count =0;

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

{

if(flagnode<i>.equals("1"))

{

count++;

}

}

if(count>0)

{

result.addValue("1");

}

else

{

result.addValue("0");

}
