Detailed Description

Post vault class.

This should be the only place that accessed the database.

This class should not return any objects other than post_entity objects. The class may contain some utility count methods which return integers.

This uses the repository pattern. See: https://designpatternsphp.readthedocs.io/en/latest/More/Repository/README.html
