Workflow Reader

Reads a single workflow into a workflow port object.

Notes:

the workflow will be reset on read and internal data disregarded (except data that has been added to the workflow via the Workflow Writer node)
workflow annotations will be read but will get lost as soon as the workflow gets modified
the node will fail if the workflow requires extensions (e.g. for contained nodes) that aren't installed
components are not supported to be read in

This node can access a variety of different file systems. More information about file handling in KNIME can be found in the official File Handling Guide.

Options

Workflow: Select the workflow to read.
Workflow version: If available, select the version of the workflow to read. A limited number of versions will be fetched and provided in a dropdown menu. If the desired version is not included in the dropdown list, the option hubItemVersion can be set with a flow variable (e.g. "333" for version 333 on the hub).
Custom workflow name: An optional custom name for the workflow. If not specified, the original name will be kept.
Remove input and output nodes: If checked, all Container Input * and Container Output * nodes are removed and implicitly represented. This allows one to, e.g., combine the resulting workflow segment with other workflow segments via the new implicit input and output ports.
Input ID prefix: Prefix to be used as ids for the implicit input ports of the workflow segment.
Output ID prefix: Prefix to be used as ids for the implicit output ports of the workflow segment.
Output flow variable indicating whether workflow got reset during loading: If selected, the node creates and exports a flow variable workflow_got_reset denoting whether the workflow was (partially) executed prior import. As soon as the original workflow had at least one executed node, this property will be true. Note that the workflow in the output will be reset in either case.

Input Ports

…: An optional file system connection.

Output Ports

: The read workflow.
