I want to implement an iterative loop in my workbench. For this I have created a simple "While Loop" construct. The pseudo code is as below

 

var i, maxval;

 

i = 1;

 

maxval = 10

 

while (i < maxval)

 

{

 

i = i + 1;

 

print i;

 

}

I created a workbench

To implement the looping, the red line should be working but FME doesn't take it.

Please advise for any workarounds or what I may be missing?

Hi @josephjose, to perform iteration, you will have to create a custom transformer. See these links to learn more.

However, in some cases, creating copies of the feature could be enough and also effective, without creating a custom transformer.


Thanks for the feedback.

I read your link

https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Workbench/Workbench/transformers_custom_looping.htm

Don't find any option like described like

Right-click in the workspace and choose Insert Transformer Loop, or select the menu Insert > Transformer Loop.

I am using FME2017. Am I ahead of the game or behind?

I have posted two links. Why don't you read the first one - About Custom Transformers? There is another link to "Creating Custom Transformers" which you have to learn first if you want to implement a loop with a custom transformer.

 

Hi Takashi. I got it. Thanks

Wasn't checking it in the custom transformers
