Objects (dw::core::Objects)

DataWeave 2.2 is compatible and bundled with Mule 4.2. This version of Mule reached its End of Life on May 2, 2023, when Extended Support ended.

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 module contains helper functions to work with Objects.

To use this module, you must import it to your DataWeave code, for example, by adding the line import * from dw::core::Objects to the header of your DataWeave script.
