Mapping query

[Former Member]

Hi all,

Have a queue as shown in the figure with 3 contexts each consisting of 2 values.I want as output the 2nd value from the contexts.(That is 120,6,6).The 2nd value from contexts.

Is there any way to achieve it using standard mapping functions.

Thanks

The queue looks as follows:

SUPRESS

120
CC
0
6
CC

6
FinalContext

Hi,

please try this:

TargetField --> index [1,1] --> equalsA --> ifWithoutElse --> SourceField

The second value for equalsA is 'Constant [2]'.

The value for if = true is the TargetField again.

Sorry, it's not so easy to describe a graphic...

Regards,

Juergen

function myudf(String a[[]], ResultList result, Container container)

{

for (int i=1;i<a.length;i+=2)

if (!a[<i>].equals(RESULTLIST.CC))

result.addValues(a[<i>]);

}

result.addValue(a[1]);

for (int i=2;i<a.length;i++)

if (!a<i>.equals(RESULTLIST.CC))

result.addValues(a[i+1]);

i++;

}

see that the forum replace the [
