public final class Environment
extends Object

The environment variables for CLI commands. An instance of this class is passed to each command to give it access to environment variables. Command implementations should access environment information from this class rather than using System.getenv. In multimode, the export command may change environment variables in the instance of this class that is shared by all commands.
