Custom Transformer Parameters
Parameter | Description | ||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Password | If a custom transformer is exported, it can be password-protected. For more information, see Workspace Parameters. | ||||||||||||
Description | For information about Description parameters, see Workspace Parameters. | ||||||||||||
Incoming Attribute Preservation |
Use this parameter to optimize performance by controlling how workbench determines the output of attributes that enter the custom transformer. If you already know all incoming attributes either pass through or are dropped by the custom transformer, the All Attributes or Drop Attributes settings, respectively, allow workbench to avoid the calculations that are otherwise necessary to achieve the same results.

||||||||||||
Parallel Processing |
Specifies the number of threads the custom transformer can process in parallel.
For more information, see "About Parallel Processing" in the FME Transformers Help. |
||||||||||||
Parallel Process By | Specifies an attribute or parameter by which to group parallel processing threads. For example, if the attribute 'STATE' is specified, the transformer processes each state in parallel. | ||||||||||||
Parallel Process Groups are Ordered | If Yes, the FME engine can assume that data is inputted to the custom transformer in order for each 'Parallel Process By' parameter value. This setting provides a performance and memory boost, because the engine does not need to wait for all features to arrive before beginning a process. Set this value to Yes only if the structure of your dataset allows for data throughput in order by the 'Parallel Process By' setting. | ||||||||||||
Transformer Insert Mode | Determines how the transformer is referenced in workspaces. May depend on whether the transformer is exported or not. | ||||||||||||
Deprecated | If Yes, the transformer is no longer available for use in newly-created workspaces. It remains usable only in existing workspaces. | ||||||||||||
Check for missing attribute references | If Yes, the transformer returns a warning if an attribute is not present on the features entering the transformer. See Check for Missing Attribute References. | ||||||||||||
Enable Blocked Looping |
If Yes, the transformer can bypass its blocking behavior when used in a loop, and the following additional parameters apply:
