Introduction

The Stack connector is designed to maintain a stack variable containing a list of input files for iterative processing using the 'Loop' connector.

Params

The connector accepts 2 params : 

• Variable name : that will be referred to inside the Loop connector
• Append : a checkbox, If checked, the files will be added to the end of the stack. Otherwise, they will be prepended.

Use

The 'Stack' must be combined with a 'Loop' connector to make it useful, depending on each use case.

Example:

we set a variable named 'var', and put the loaded files from 'LoadFile2' as value.

then, we retrieve this variable using the 'Loop' connector, and iterate over the set, and make a limit of iterations as 20. 

inside every iteration we add a new file coming from the 'XMLToXML1'. and we chose to append ie add files at the end of the array.
