Container Output (JSON)

JSON related functionality for KNIME version 3.7.0.v201811121404 by KNIME AG, Zurich, Switzerland

Reads the content of a JSON column and makes it available to an external caller. This node is used in KNIME server web services, where the result of the web service is represented by the input of this node. By default a JSON array is returned, where each row of the input table is an element in the array. Tables with no or only one row result in an array with zero or one element. This behavior can be changed in the dialog, see the settings below.

Options

Parameter Name
A name, which serves as key in the resulting JSON object. This is used to assert uniqueness in case multiple output results (nodes) are present in workflow.
JSON Column
The column containing the JSON result. All other columns are ignored.
Description
A description for the output parameter. The description is shown in the API specification of the REST interface.
Keep single-row tables simple
For the special case that the input table contains one row with a non-missing JSON value this value is taken as result and not wrapped into a JSON array.
Example
A JSON representing an example of what output received by this node may look like. Mainly used for populating the "example" field of the generated OpenAPI output parameter specification, which is presented to end users for documentation purposes. The content of this node can be filled from input data (if preceding nodes are executed.)

Input Ports

A table containing a JSON column whose content is made available to the caller.

Views

JSON Snapshot
Shows the JSON structure as read from the input (possibly converted into JSON array)
