Java UDF One as Many

[Former Member]

Hi,

I would like a function to copy an array (my second queue) as many times as there are values in my first queue.

So for example

Queue 1

1

2

3

4

Queue2

A

B

Result

A

B

Context Change

A

B

Context Change

A

B

Context Change

Hi,

public void calculate(String[] Item, ResultList result, String[] repeat, Container container) throws StreamTransformationException{
for(int i=0;i<repeat.length;i++)
{
for(int j=0;j<Item.length;j++)
{
result.addValue(Item[j]);
}
result.addContextChange();
}
}

Input :

Queue1

A

B

Queue 2

Result

A

B

Context Change

use this UDF

for(int i=0;i<queue1.length;i++)

{

for(int j=0;j<queue2.length;j++)

{

result.addValue(queue2[j]);

}

result.addContextChange();

}
