Function

The following table provides information regarding the 'Function' SFCodeBlock.

Function SFCodeBlock

Category	Description
Description	Identifies the beginning of a function. All stacked SFCodeBlocks belong to the function. Functions are recursive and can call themselves during the execution. Functions are also re-entrant, but you have to consider that SFStudio handles global variables only, therefore you are responsible for it.
Input	Working Space of caller, i.e., all AFElement
Parameters	None
Pattern Support	No
Returns	Working space of the caller, i.e., all AFElements received in input.
Configuration	You are required to enter the function name. To enter a function name: 1. Click on the code block text. 2. In the Shape Name box, type a name for the function. 3. Click Save. It is your responsibility to avoid duplicated function names in the context of the same SFHubStudio analytic (duplicated names are not detected). You can rename an existing function by clicking in the text box and entering the new name in Edit Function Name pop-upwindow.

Iportant Note

Renaming a Function requires you to change the 'Call' and 'Task' code blocks that refer to the old function name. References to missing Functions raise the following error when the analytic is saved:
