All Implemented Interfaces:

Closeable, AutoCloseable, Readable

public class CommentStrippingReader
extends Reader

A reader that filters out block and line comments.

Note: This is not a full function comment stripper for JavaScript files. In particular, it doesn't support JavaScript regular expressions, and may improperly recognize comment start and end tokens inside regular expressions. It does the job for what we need, though, which is removing comments from CSS and server-side JSON files.
