/**
 * The environment for an rmic compilation batch.
 *
 * A BatchEnvironment contains a RootDoc, which is the entry point
 * into the doclet environment for the associated rmic compilation
 * batch.  A BatchEnvironment collects the source files generated
 * during the batch's execution, for eventual source code compilation
 * and, possibly, deletion.  Errors that occur during generation
 * activity should be reported through the BatchEnvironment's "error"
 * method.
 *
 * A protocol-specific generator class may require the use of a
 * particular BatchEnvironment subclass for enhanced environment
 * functionality.  A BatchEnvironment subclass must declare a
 * public constructor with one parameter of type RootDoc.
 *
 * WARNING: The contents of this source file are not part of any
 * supported API.  Code that depends on them does so at its own risk:
 * they are subject to change or removal without notice.
