Write Variables
Vernalis Flow Control extension for KNIME Workbench version 1.20.1.v201906111356 by Vernalis (R&D), UK
The Write Variables node writes flow variables to disc. They can be read back into a workflow in using a Read Variables node. 'Special' variables (i.e. those whose name starts 'knime.') are ignored, as these have special meanings in KNIME.
This node was developed by Vernalis Research . For feedback and more information, please contact knime@vernalis.com
Options
- Selected file
- Select a *.variables filename to save the flow variables to. Other file extensions will fail.
- Overwrite existing file?
- An existing file will be overwritten following a warning if this is checked.
