TempPathnameCreator

Reserves and returns a temporary file or folder path that will be deleted upon translation completion. An optional basename and extension can be supplied to further refine the filename portion of the resulting pathname.

This transformer is typically used in conjunction with the FeatureWriter or AttributeFileWriter in workflows that need a temporary file location that will live only for the duration of the translation. The files are then typically consumed downstream in the workflow by transformers like the Emailer or HTMLReportGenerator.

Pathnames

The resulting pathnames will look something like:

<FME temporary directory>/<process #s><TransformerName>_<uuid>/<basename><timestamp>_
<sequence #>.<extension>

For example, on Windows, the transformer will create a path that looks like this:

C:\temp\1457417_4341TempPathnameCreator_820b3a46_e4ee_11e5_8cb1_
a45e60c7b3170\base_4672334_0.ext

And on Linux/MacOS, the transformer will create a path that looks like this:

/tmp/1457414874617_4341TempPathnameCreator_820b3a46_e4ee_11e5_8cb1_
a45e60c7b3170/base_4672334_0.ext

The FME_TEMP environment variable can override the default location for temporary folders. See https://knowledge.safe.com/articles/176/fme-temp-environment-variable.html for more details.

Each instance of this transformer will itself create a subfolder within the temporary folder in use, and return unique paths within that subfolder. This subfolder and its contents will be destroyed at the end of the translation, but before any END_PYTHON or END_TCL scripts are invoked.
