Tree (dw::util::Tree)

DataWeave 2.2 is compatible and bundled with Mule 4.2. Standard Support for Mule 4.2 ended on May 2, 2021, and this version of Mule will reach its End of Life on May 2, 2023, when Extended Support ends.

Deployments of new applications to CloudHub that use this version of Mule are no longer allowed. Only in-place updates to applications are permitted.

MuleSoft recommends that you upgrade to the latest version of Mule 4 that is in Standard Support so that your applications run with the latest fixes and security enhancements.

This utility module provides functions that enable you to handle values as though they are tree data structures.

The module is included with Mule runtime. To use it, you must import it into your DataWeave code, for example, by adding the line import * from dw::util::Tree to the header of your script.

Introduced in DataWeave 2.2.2. Supported by Mule 4.2.2 and later.
