Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Note:

internal only, unstable API

The goal of this class is to write the data stored in AugeasTree back to Augeas.

It tries to make only the needed changes, as internally Augeas keeps a flag whether data has been modified, and keeps the unmodified parts of the file untouched.
