import ( "k8s.io/kubernetes/pkg/kubectl/cmd/util" ) encoderFactory := util.NewFactory(nil) encoder := encoderFactory.NewEncoder(outputFormat)In this example, the NewFactory method is called with a nil value, meaning it will use the default settings. The NewEncoder method is then called on the factory, passing in the desired output format. This package library is part of the Kubernetes command line tool kubectl. It includes various utility functions for working with Kubernetes resources through the command line.

The JSONEncoder in this factory is just one of the many utilities provided.
