Container Input (Variable)

JSON related functionality for KNIME version 4.2.1.v202008251158 by KNIME AG, Zurich, Switzerland

This node receives flow variables from an external caller (i.e. the Call Workflow (Table Based) node) and makes them available to the workflow. A configured parameter makes the Container Input (Variable) visible from the external caller and enables the external caller to send the variables to the Container Input (Variable) node.

Options

Parameter name
A name for the variable input parameter(preferably unique). This name is exposed in the REST interface and in the Call Workflow (Table Based) node.
Append unique ID to parameter name
If checked, the name set above will be amended by the node's ID to guarantee unique parameter names. Usually it's a good idea to have this box not checked and instead make sure to use meaningful and unique names in all container nodes present in a workflow.
Description
A description for the variable input parameter. The description is shown in the API specification of the REST interface.

Input Ports

Icon
An optional input that is directly forwarded to the output of the node, unless overwritten by supplying variables via the REST API.

Output Ports

Icon
The injected variables, default variables if none has been injected.
