how to add string lists

[vannur1 (vannur *)]

Hi,Please can you say how to add two string list and store that result in string list.each string has five elements and how to add document list also ?

Hi Vannur,

1.WmPublic/pub.list:appendToStringList
Map the Stringlist1 to toList serviceIn parameter and stringList2 map to fromList then serviceOut parameter toList parameter contains the both values.

do the same proceess for documentList also
2.WmPublic/pub.list:appendToDocumentList

Hi jeevan,sorry because I did not explain briefly,I want add two stringlist values as per their array position,i.e I expect as per below type,please can you say alternate way…

sl1[0]=10; sl2[0]=10; output string list sout[0]=20;
sl1[1]=20; sl2[1]=20; sout[1]=40;
sl1[2]=30; sl2[2]=30; sout[2]=60;
sl1[3]=40: sl2[3]=40; sout[3]=80;
sl1[4]=50; sl2[4]=50; sout[4]=100;

one way to achive it:

inputListA
InputListB

OutputList

Loop over inputListA (with no output array)
{
$Iteration = IterationA
Loop over InputListB (with output array as OutputList)
{
$Iteration = IterationB
If (IterationA=IterationB) —Implement with branch
{
a+b = tempout – (Use pub.math.addInts)
appendtoStringList/DocumentList (append tempout value in from item and constiture your outputList)
}
}

– Hope its simple n understandable, let me know if you got qustions

cheers!

In my opinion, your best bet would be to probably do it in Java. Here’s sample code for a Java service that takes two String Lists, a and b, and outputs c. NOTE: the code assumes b is the same length as a.

IDataCursor cursor = pipeline.getCursor();
String a = IDataUtil.getStringArray( cursor, “a” );
String b = IDataUtil.getStringArray( cursor, “b” );
int length = a.length;
String c = new String[ length ];
for( int i = 0; i < length; i++ )
{
c[i] = Integer.toString( Integer.parseInt( a[i] ) + Integer.parseInt( b[i] ));
}
IDataUtil.put( cursor, “c”, c );
cursor.destroy();

Now if you want to stick with Flow, you can do something similar with three simple steps. Suppose the service takes the same inputs, a and b, and outputs c:

LOOP over ‘a’ (with output array as ‘c’)
– Invoke pub.math:subtractInts to subtract 1 from the variable $iteration and map the value to a variable called index, for example.
– Invoke pub.math:addInts: map a to num1, map b to num2 but click on the link, go to the Properties section (upper right corner), click on the Edit button next to Indices, and set the index of b to %index%. Map value to c.

That’s it!

Good luck,
Percio
